A few months ago, a young cardiologist told me that he rarely listens to hearts anymore. In a strange way, I was not surprised.
He went on to tell me that he gets all the information he needs from echocardiograms, EKGs, MRIs, and catherizations. In the ICU, he can even measure cardiac output within seconds. He told me that these devices tell him vastly more than listening to out-of-date sounds via a long rubber tube attached to his ear.
There was even an element of disdain. He said, “There is absolutely nothing that listening to hearts can tell me that I don’t already know from technology. I have no need to listen. So I don’t do it much anymore.”
I began to wonder. I called my longtime friend and colleague, also a cardiologist. I knew him to be one of the best heart listeners. I asked him if he still listens to hearts. He answered, “Of course I do. I could not practice medicine if I didn’t. But you know every week, several patients tell me when I listen to their hearts that I am the first doctor ever to do that. Can you imagine that?”
Playing the devil’s advocate, I challenged my friend to tell me what he learned from listening to hearts.
He answered, “How could anyone not want to hear those murmurs, sometimes ever so soft, like whispers? Murmurs from the heart, even very faint ones, are trying to tell us significant things. Some sounds are very localized, even hidden or obscured by layers of air. And then there is the rhythm and the beat and the cadence that you cannot hear on the paper strip of the EKG. Also, careful listening is the only way to appreciate the rubs of friction if there are any. The devices are important, but the heart has its own spoken and unspoken language if you know how to listen.
