The BIZARRE History Of The Human Heart

How come we draw

heart

s like this but the

heart

s actually look like this? Is it true that King Charles once touched the beating heart of a living child? Is it possible to live with a 3D printed heart? This is the strange past, present and future of the

human

heart. Thank you very much Tom Ron for sponsoring this video 15,000 a. C., long before we knew what a

human

heart really looked like, the oldest known representation of a modern heart symbol was created in Spain with an El Pindal cave. Remains of cave paintings from the first hunters. The collectors show a woolly mammoth with the heart symbol located right on its torso.

Almost nothing is known about these paintings, such as who made them and what they mean, but some experts speculate that paintings of animals such as the woolly mammoth may have been instructions. Knowing where to attack with Spears while she hunts isn't exactly a romantic origin story, although 12,000 years later, the Egyptians began to identify the heart as the center of life and mortality. The Egyptians believed that the heart was responsible for things like emotions, wisdom, and memory. In fact, the Egyptians revered the heart so much that during mummification the heart was left inside the body and not removed like other organs because the heart was believed to be necessary in the afterlife.

The gods took the heart, which was often depicted as a jar with two small handles, and weighed it as a form of judgment. The Egyptian god Anubis would weigh your heart against a feather. If they weighed the same. You would be blessed in the afterlife if your heart. If it weighed more than the feather you would be cursed into oblivion because of all the guilt and evil. This is also believed to be potentially the origin of the phrase having a heavy heart. The ancient Greeks took this a step further, not only did they believe that the heart contained a person's soul, but that it had a functional mechanism within the human being.

The world's first physician, Hippocrates, and the ancient Greek scholar Aristotle believed there was a connection between the heart and the lungs, so they spent years discussing the importance of the heart's pumping action. Aristotle developed these theories after studying embryos of chicks that were not really human and while he may have gone in the right direction, he was wrong in some places Aristotle believed that the heart had three chambers, in reality it has four, he believed that the function of the heart was to warm the body I guess you could say that's true because the heart pumps blood which helps in thermoregulation.

He also theorized that the organs were intended to cool the heart. No, that's too much because we have sweat glands for that, so while it's not entirely accurate, the Greeks were definitely making some progress 700 years later around the world. In the Mediterranean, the city of Sireni in Libya began issuing silver coins depicting the heart symbol, but was it actually the heart symbol or simply the leaf of a plant called sfum? Well, it may actually have been both because in the ancient world sfum grew naturally on the northern coast of Africa and was considered a miracle drug to treat countless problems;

In fact, it was so sought after that Caesar was rumored to have stored 1,500 pounds in the Roman treasury. Since sfum was used as an aphrodisiac and contraceptive, historians speculate that the plant's heart-shaped leaves may have actually been the origin of the association of heart symbols with love and romance, sadly due to its extinction probably due to over-harvesting, we will never know if it was a cure-all or nothing more than an ancient Flash glue Fast forward another thousand years or so and The emergence of Christianity gave rise to the Sacred Heart, this religious symbol associated with Jesus Christ created some visual representations that began to resemble the beginnings of the anatomical version of the heart, although it was still a form.

Far from what a real heart looks like, these representations They exploded and appeared in Christian monasteries in Europe and the Middle East, were shown in thousands of religious texts and are still used today for ceremonial purposes and in the names of countless schools, hospitals as well as other institutions around the world during the Middle Ages. In the Middle Ages, cultural representations of the heart extended far beyond the boundaries of religion and were used in art to represent royalty. The heart also made its first appearance on one of the world's most popular items, something you can actually see.

Have in your home right now playing cards initially developed in Asia, playing cards reached Europe, where different cultures experimented with different suits. The 15th century Germans were the first to implement the heart suit, which is still found at poker tables and campfires today, while the heart was finding its way into culture, real scientific progress had been made. stagnant for more than a thousand years due to its religious persecution during the Middle Ages. You see back then, when someone died, you had better carry them and move on to the idea of ​​performing a dissection or examining a corpse.

It was simply not common and was often publicly condemned. It was only during the Renaissance that Leonardo da Vinci and eventually others were bold enough to begin dissecting human and animal bodies for research. This gave Da Vinci the opportunity to become the first artist to sketch a truly accurate depiction. of the heart was meticulous with his work managing to accurately capture diagrams of the heart with nothing more than pens and paper and although his work dramatically improved our understanding of the heart it was not without conspiracies Da Vinci never published the drawings himself and in the margins of the diagrams he even wrote could say more if I was allowed to do so unfortunately science during that time was very corrupt and even silenced by religion and the oppressive Spanish Inquisition.

Fortunately, the Renaissance would soon lead to the Age of Enlightenment where science and art would be freed from these confines, one must wonder how many more discoveries da Vinci would have made if he had not feared persecution. Now, in the 17th century, a 10-year-old boy named Hugh Montgomery was riding a horse through the English countryside. the horse pushed them off and threw him into the air and Hugh landed chest first on a rock or jagged fence. There are several stories about this. The injury was so devastating that it shattered Hugh's ribs and left an open wound right in the middle of his chest.

Miraculously even though he was young. Hugh survived, but not without what would become one of the most famous scars in the world. He was left with a huge hole in his chest and his beating heart was completely exposed to the naked eye. Never before in recorded

history

had any human being seen a live beating heart. In fact, they initially thought it was his lungs they were looking at, not even his heart. Hugh not only survived but flourished as he began his tour across Europe, amassing desperate crowds who wanted to see a real human heart for themselves, one of those people, King.

Charles I, who summoned Hugo for a royal examination, the king was fascinated, getting closer and closer to Hugo to put his eyes and his hand on the beating organ, the king reached in and touched the heart with three fingers on his thumb. . It hurts? The king asked right? all he answered Royal physician William Harvey documented the boy's unique case and verified its legitimacy, opening the door to further research into the cardiovascular system. The Hugh incident was obviously scandalous and it's unlikely you'll ever find yourself in the same situation, but that's not the case. This doesn't mean there aren't heart problems you should watch out for, which is why I want to talk about hypertension, courtesy of our sponsor Amron, the #1 home blood pressure monitor recommended by both doctors and pharmacists according to American Heart.

Association 116 million Americans fall into the high blood pressure range each year, which is the leading cause of heart attacks and strokes which, fortunately, can often be prevented by focusing on certain lifestyle habits, such as a healthy diet, regular exercise and avoiding tobacco products, those habits help keep your blood pressure under control also monitoring your blood pressure at home can help keep it in a healthy range, allow you to identify high readings sooner and, most importantly, get accurate measurements, since many people have higher numbers when in the presence of a medical professional. Even download the Omron Connect app, which will give you valuable information about your lifestyle habits and allow you to share your readings with your doctor.

I can't tell you how valuable it is to me as a primary care physician. Visit the link in the description below. To learn more about Omron home blood pressure monitors so you can monitor your blood pressure effectively and easily, we can't talk about the heart without talking about Valentine's Day. The actual origin of Valentine's Day is highly controversial, but many believe that it began as a religious ceremony in Rome in honor of Saint Valentine, who could be any of the three gentlemen called Saint Valentine formally recognized by the Catholic Church. How the Roman ceremony came to be a lovers' feast is widely unknown, but it appears that displays of romance began around 1375, when the English poet Jeffrey Chooser wrote for This Was Sent on Valentine's Day, When Every Miss Comes There to choose your partner.

It was around this time that the heart also began to appear in pop culture as a symbol of romantic love. The first non-anatomical illustration of the heart may be from around 1255 CE in a French poem called Romance of the Couple along with an image of a man kneeling beneath a woman offering her a heart or a couple, difficult to tell in 1550, the King Christian compiled a collection of 83 Danish love ballads. III inside a heart-shaped book, no doubt this is a book of love, but in the mid-18th century a few smart businessmen thought they could earn a few coins with the day and so began the commercialization of love with sellers who They sold formal Valentine's Day cards.

As can be seen from this card from 1818, the heart symbol had already seen a good and profitable use that we still see today in the early 19th century. Heart research was pumping. Sorry, I had to do that. LED lighting doctors around the world to perform autopsies and achieve more scientific advances than had been achieved in the last 2000 years. In 1801, a Spanish doctor named Francisco Romero became the first doctor to successfully perform surgery on the human heart, making him the first cardiac surgeon, a title that does not exist. Although he still exists, he operated on the hearts of several patients. for several years, but generally with mixed results.

He then presented those findings at the Paris Medical School to a very lukewarm reception, while we now recognize his surgery on cardio parico, the lining of the heart as revolutionary his peers largely disagreed, calling his surgeries too aggressive and silenced them for years in 1925 Henry Sutar, a doctor and engineer who began to be a pioneer. Innovative surgical techniques saved the life of a 15-year-old girl by performing heart valve surgery using a technique that was radically different from what his colleagues had previously attempted, there was so much opposition from them that he was threatened with a murder charge. involuntary if the surgery proceeded and failed, while the operation was successful and the girl lived several more years in the medical community.

She was shocked by the procedure and never allowed him to do it again. It was another 22 years until other doctors reviewed their notes and realized that Dr. Satar was right, making his once Bann surgical technique the norm for years to come. World War II unleashed innovation. in virtually every scientific sector, especially in medicine, where doctors in several wartime countries pioneered innovative technologies around anesthesia and transplants, for example, plastics developed in military laboratories were eventually used to manufacture artificial heart valves for all the destruction that wartime may have been responsible for. The medical progress that followed in the decades that followed was truly revolutionary.

In 1967, Dr. Christian Bernard of South Africa performed the first heart transplant by removing the heart from a young woman who had died in a car accident and giving it to a 53-year-old man. He suffered from severe coronary insufficiency, the operation was an initial success and the press coverage was unprecedented. It really went viral. Dr. Bernard had become an international superstar for performinga procedure that was long thought impossible. Reporters around the world covered the patient's recovery in extreme detail. about his every move and meal, but unfortunately the good news did not last long. Only 18 days after surgery, the patient developed and died of severe pneumonia and septicemia, a blood infection, although this was tragic.

Dr. Bernard had shown that heart transplantation was possible. and that improvements needed to be made over the next decade, doctors and scientists are working to solve the problem of organ rejections during heart transplants, which made the procedure less likely to be successful in the long term; the only problem left was waiting for a heart to become available which could be a long and lethal process, sometimes taking years to get a heart, a couple decades of research later people who needed a new heart finally had an option while waiting for one to become available, they were sometimes able to qualify for an artificial one.

Dr. Robert Jarvi invented the Jarvic 7 artificial pump which could be placed in a failing heart and act as a bridge until a new heart was available in 1982. The Jarvic 7 artificial heart was placed inside Barney Clark, who survived 112 days with it in 1985. It was placed inside a 25-year-old Michael Drummond, who lived with the pump for 9 days before a donated heart was found, making him the first human to successfully survive a heart transplant artificial. The jarvic 7 is considered such a revolutionary piece of technology that it is now on display. at the Smithsonian Museum in Washington DC which brings us to what's next: the advancement of hard technology.

Technology is expanding into a new dimension, literally scientists around the world are developing 3D printed hearts that can have the same form and structure than the heart they seek to replace. Imagine a world where you no longer have to wait for a tragedy to happen before you can receive. A heart transplant instead of a printer could generate a synthetic heart that looks identical to the heart you already have, except it's made of more durable material and can even fix pre-existing problems. These 3D printed hearts could also be used for various forms of medical research. You could try all kinds of surgeries and procedures on a 3D printed heart without putting anyone's health at risk, and with the emergence of AI in the healthcare sector, it seems like we're only scratching the surface of what's possible when it comes to treat our ticks. some modern medical practices.

I think it's absolutely necessary that we stop clicking here to check it out and, as always, stay happy and healthy.
