There are some amazing stats surrounding the world of cardiology, and I thought you might be interested to know a few of them…
• Ancient Egyptians believed the heart was the centre of intelligence and emotion, not the brain, which is why during mummification, they removed the brain but preserved the heart because it would be needed in the afterlife for judgment.
• In 1780, Luigi Galvani discovered that electricity could make a frog’s heart twitch - laying the foundation for our modern understanding of electrophysiology and defibrillation.
• Dr. Ludwig Rehn in Germany performed the first successful heart surgery - he sutured a stab wound to the right ventricle in 1896.
• In 1958, the first internal pacemaker was implanted - but earlier prototypes in the 1950s were external boxes plugged into wall outlets.
• Until the 1960s, closed-chest cardiac massage (now called CPR) was not standard. Before that, most cardiac arrests were treated with open-chest compressions or direct massage during surgery - obviously impractical outside an OR.
Any that really surprised you?
