From Einthoven's Discovery to Modern Heart Health: A Century of Progress

A hundred years ago, Willem Einthoven changed the way we understand our hearts. He was awarded the Nobel Prize for figuring out how to read the heart's electrical signals, a process we now call electrocardiography. This method lets us see the heart's activity on the body's surface, which is pretty amazing when you think about it. Einthoven's work didn't stop at just observing. It inspired others to explore how to control these electrical signals. This is where things get cool. Scientists are now looking into ways to stop irregular heartbeats, or arrhythmias, by manipulating these signals. One promising method is called optogenetics, which uses light to control the heart's electrical activity. The impact of Einthoven's discovery is huge. It's not just about diagnosing heart problems; it's also about finding new ways to treat them. His work continues to influence how we understand and treat heart conditions today.
