The doctor feels our heartbeats with the help of an instrument called _______.
stethoscope
A stethoscope is an acoustic medical device that amplifies internal body sounds — particularly heart sounds and breath sounds — and conducts them to the examiner's ears. Doctors place its chest piece on the patient's chest to hear the 'lub-dub' sounds of the heartbeats.
Radiography uses X-rays to image internal structures; a reflex hammer is used to test neurological reflexes; a microscope magnifies small objects for visual examination. None of these detect heartbeats by sound.
