Electronic Stethoscope

The stethoscope hasn’t undergone many significant breakthroughs until now. 3M’s new stethoscope listens to a patient’s heartbeat, captures the sound for later playback, lets you transmit sounds real-time to your PC, which can then be further analyzed, attached to medical records, or reviewed online with colleagues.

The sound-amplifying 3M Littmann Electronic Stethoscope 3200 will not only be able to catch dangerous murmurs and heart defects but will also eliminate more than eight millionunnecessary echocardiograms and cardiologist visits a year, saving some $9.4 billion
