THE QUESTION

I was recently in a hospital for a medical appointment and noticed some doctors with stethoscopes around their necks. Then I read an article in the newspaper that said the stethoscope was invented 200 years ago. I find it strange that doctors are still relying on them. Isn't there something better?

THE ANSWER

It's true that doctors have been using the stethoscope for two centuries to assess the hearts, lungs and bowels of patients by listening to the internal sounds of their bodies.

The first stethoscope – an improvised hollow tube – was developed in 1816 by a French physician, René Laënnec, who essentially felt embarrassed about putting his ear on a woman's chest to hear her beating heart.

Since then, the stethoscope – with its disc-shaped resonator and two tubes connected to earpieces – has become a symbol of the medical profession.

But in recent years there have been calls for doctors to ditch the stethoscope and adopt high-tech devices.

Eric Topol, director of the Scripps Translational Science Institute in La Jolla, Calif., is one of the leading proponents of the "digital" health revolution, which promises to put personal health information directly into the hands of patients.

Dr. Topol calls the stethoscope a "relic," noting that pocket-size ultrasound scanners can now provide detailed images of the heart. Other devices that connect to smartphones can amplify heartbeats, help with diagnosis, and the data can be sent wirelessly to patients' electronic medical records.

These advances certainly seem impressive and there's little doubt that medicine is heading down the high-tech highway.

However, there are still occasions when low tech can be good tech, says Donald Redelmeier, a staff physician at Sunnybrook Health Sciences Centre and a professor of medicine at the University of Toronto.

"The stethoscope isn't perfect, but it isn't completely ready for the rubbish heap," says Dr. Redelmeier, who has a reputation for challenging conventional medical wisdom.

He can think of several examples where the old-fashioned stethoscope is more than sufficient to do the job. These include:

In each of these cases, Dr. Redelmeier says a "more ideal, more exact and more elaborate assessment" can be done. But sometimes the trusty stethoscope is the practical and preferable choice.
