The BIZARRE History Of The Human Heart

[@vidyalakshmi7384]

Sushrutha, an ancient Indian scholar known as the father of plastic surgery, has perfomed dissection in cadavers before the time of Christ. He has described in his book "Sushrutha Samhitha" about how he prepared the bodies for dissection, his findings, along with diseases and cure. Although many of his findings may not be agreed by contemporary science, he was a pioneer in this field and his works are still referred in the alternative medical system. He has described the position, shape, and has also highlighted the vitality of the heart. His photo is hung in many hospitals across India and parts of the world as a form of respect. In India, the healthcare system is a combination of modern medical doctors and alternate medical practioners. Susrutha is a significant intersection between the two. If you've read till here thank you 😊 and thanks to Dr.Mike for the amazing video!

[@birdbrainz32]

Thank you so much for sharing that! You just taught me something new!

[@Anish_Bhai24]

7:01 That beating heart story is insane! How does someone survive that….

[@lool8421]

even if internal organs weren't damaged, how the hell do you avoid all the infections?

[@KalashDaCat]

@@lool8421 Dude probably took alcohol baths and had an anomalousy good immune system.

[@red.aries1444]

@@lool8421I don't think the heart laid completely open, some tissue would still cover it. But it wasn't enclosed in the ribcage anymore. This may have caused a pneumothorax, but maybe the boy survived with only one lobe of the lung still working. You could then really see and feel the pumping heart. That's much stronger than only to feel a pulse in a blood vessel.

[@Hoxterjr]

I am not sure if the story was even real. I can’t find anything about it, not even ChatGPT. If you guys know anything please share.

Right?! How’d he not die of blood loss?! 🤔

[@NanaRezelj]

I loved this timeline, but as an Argentinian girl, it's sad that he didn't include Dr. René Favaloro. He performed several heart related procedures, such as the bypass, and it was very important for medical history. 🇦🇷❣️ Always remembered here!

What's even cooler about 3D printing hearts, is they can use your genetic code to not only fix defects on the printed heart, but it will bypass rejection. No dampening your immune system post transplant for the rest of your life. This is also progressing other organ replacement research as well.

[@braga_6850]

That’s so awsome! But for now, we’d better take good care of our organs and not expect for new ones 😅

[@Kirmeins]

How does that progress other organ replacement? I thought that other vital organs all have complex metabolic tasks to fulfill which no printed organ shell could fullfill, right? So I'd wager that unless they can fill those shells with equally immune friendly tissue that can metabolize whatever is needed, this doesn't help? I'm truly curious now! :)

[@rivertam1000]

If the structure of the artificial organ is correct and stem cells induced to form that tissue it could be functional :) ​@Kirmeins

[@justinmcgough3958]

​@@Kirmeins Thats where the research into stem cells come in. For now 3D printing research is getting the building of the organ structure and placement of cells underway, but with stem cells you can then potentially fill in the gaps of 3D printing. And 3D printing organs isn't as simple as it sounds, they amount of research into the structure of organs, the placement of cells, the binding of those cells, and the work to get the whole organ functional is all key parts of that research that will overlap into other organs.

[@icarusbinns3156]

When I was in the hospital with a nasty infection from a pulled tooth (I’m resistant to amoxicillin), one of the concerns was bacteria setting up colonies in my heart on the valves. The tech that brought in the machine to get basically an ultrasound of my heart admitted that it never got old, seeing a heart in action. I was in awe. Good thing Mom was there, to ask the questions I was too stunned to remember.

[@Americanlynn1]

Thanks to your videos, I was inspired to take the class and become CPR certified. I can now correctly do those chest compressions should the need ever arise ❤. @Doctor Mike

[@agustinamanzo3860]

What a great video! For anyone interested in the history of medical procedures, another date to add to the timeline: May 9th, 1967, the first Coronary artery bypass surgery (CABG). This procedure was performed by Argentinean doctor René Favaloro in Cleveland, USA. The surgery, as Favaloro standardized it, is the main treatment for coronary artery disease. It has saved and improved millions of lives by relieving symptoms, preventing heart attacks and increasing life expectancy for CAD patients. It´s considered one of the "400 most important inventions for Humankind". 1967: Heart transplants and bypass surgery, what a great year for cardiovascular health!

I wish you and your family a fulfilling life of happiness and cherish-able memories 😊

[@tazzyanderson1192]

As a young South African infant who dreamt about being a doctor and thought she knew way more than she did, Dr Christiaan Barnard was a huge role model and inspiration to me! Whilst most children my age wanted to be superheroes, pop stars, princesses, sports stars etc. I wanted to be the first person to perform a heart transplant. After I was told that heart transplants were already a thing I immediately went for "Okay then, the first person to do a brain transplant". When told it was impossible I directly replied with no hesitation: "They probably believed heart transplants were impossible until someone did it." It was clear that I was too young to understand how the brain works (I just figured you took it out and sewed it into the next person and the receiver would be no different), but there was no arguing with my solid response Still now, (a slightly older South African woman who still thinks she knows more than she does, and still dreams of studying medicine) Dr Christiaan Barnard is a huge inspiration!

[@tazzyanderson1192]

I have to add that Dr Barnard's first heart transplant was and is deemed the first *successful* heart surgery. The patient's new heart kept beating until his death, so whilst the surgery may have led to a fatal infection, the heart was working perfectly well after surgery.

[@tjeerdprins869]

Hippocrates probably didn’t mean ‘the heart heats the body’ in a literal sense. As Galen explains in his text ‘Hygiene’, blood in the Greco-Roman era was thought of as containing slightly more fire (fiery matter) than any of the three other elements (earth, water, air). These elements had to be in balance in order to be healthy, so blood had to be in balance with the three other humors (fluids, each with their own properties). So the heart provided the heat, but probably figuratively. I’ve read some of the translations of these ancient texts. I’d really recommend it. It’s so interesting to see what the views of these people were, so long before science was a thing. I’ve even read a section that sounds surprisingly similar to germ theory (Galen’s Hygiene too). Anyways. Thanks for the content :)

Hi Dr. Mike, Thank you for such an intriguing video about the history of the heart symbol! It was fascinating to learn about its origins. However, I wanted to mention that during the Dark Ages in Europe, the Islamic Golden Age was thriving in the Middle East. Scholars like Ibn Al-Nafis made significant contributions to science, anatomy, biology, math, poetry, mosaics, and architecture. In fact, Ibn Al-Nafis, a Muslim scholar born in 1213 AD in Damascus, Syria, was the first person to discover blood circulation in the human anatomy. He described the pulmonary circulation of the blood, laying the foundation for our understanding today. His contributions were truly groundbreaking and played a crucial role in the advancement of medical science. Thank you for your enlightening content! This is what really upsets me - there’s always missing narratives about the Islamic world during the Middle Ages. A lot of tools and advancements that doctors today are using came from the Muslim world during Europe’s dark time. Dr. Mike, this is not OK! Even algebra and algorithms originated from the founders in Central Asia

[@thecollierz4996]

As a Christian, I really respect how Mike is non judgmental to religion and choice, while I can’t say if Mike is religious or not, he does know that it does matter to some people , Mike brings science up in a way that doesn’t challenge religion but just lets us know what’s going on inside.

I also love looking at my BP readings from every time I give blood and I once took all of my readings from my donor cards and did the math to find my average and it was 118/76 and it made me so happy, lol, yes I’m that kind of person, haha.

​​​@@dumindunadun1298just go pick a fkng book. The circulation theorem and the heart model was given by middle easterners, especially Ibn sina (avicenna) who performed surgeries in a time people couldn't cure colds. Also the fact that the heart acted like a pump. They theorised it, and also avicenna theorised the heart beats faster during stress therefore human psychology and emotions puts and effects on the circulation system by providing more blood to body parts and the brain.

[@DovahGirlie]

[@MilicaIlicic]

Awesome overview! However, there's one meaningful omission: even though medical advancements largely stalled in Europe in the middle ages, physicians of the Islamic Golden Age made some stunning progress that's worth mentioning - in good part because it's important to dispel the notion that science only happened in Europe and the (Christian) West. Quote here for fellow history buffs: "Ibn Al-Nafis (born 1213) goes down in the history of medicine as the first scholar to understand the respire-circulatory system, although his knowledge was incomplete. He understood that the heart was divided into two halves and stated that there were no pores connecting the two halves of the heart, as proposed by Galen. Al-Nafis stated that the blood could only travel from one side of the heart to the other by passing through the lungs. This was the first example of a scholar divining the nature of the pulmonary system. Although he was unsure of the mechanism, Al Nafis correctly observed that the blood in the lungs mixed with air, although he also proposed that the blood was also infused with 'spirit' in the left cavity of the heart. His other observation was that the heart was nourished by the web of capillaries surrounding it not, as proposed by Avicenna, the right ventricle of the heart. He touched upon the subject of the role of capillaries in circulation, proposing that the pulmonary artery and vein were linked by microscopic pores; it would not be until four centuries later that this theory was rediscovered and the idea of capillaries was extended to the rest of the body."

Dr. Mike, maybe you might have heard or not, that actually a very learned man Rishi Sushruta was one of the very first one to have done dissection on dead bodies in India, & document all of it in Sushruta Samhita, even after being condemned while doing so, he didn't stop, & is truly a great personality, & we are immensely Grateful of him

This was so fascinating and so well presented! It’s interesting the contrast between the fear and suppression that greeted medical innovation pre-20th century versus the excitement and media coverage that greeted the first heart transplant in 1967. I guess the general public and our institutions gradually learned that science was a net positive rather than something suspicious and heretical.

A part time career in history narration is a possibility! Love the voice and clear concise language. The passion too made this video engaging and fun

I really do love exploring and learning about early medicine, even the earliest foundational forms of basic discovery of human anatomy and biology is just breathtaking to me, I wish kids these days we get fascinated with such knowledge, I remember growing up wandering how my body works.
