What Instrument used to listen to heartbeat?

Answer 1

The heartbeat can be measured in several different ways, the most common being to count the beats to get the heart rate - beats-per-minute. This can be done with a watch and a finger on an accessible blood vessel, an artery.

Or you can take an electro cardiogram, where an electronic instrument is attached by leads to the chest and picks up and registers the tiny electric impulses that controls the heart.

Or you can use a stethoscope and listen to the beats.

Or you can use an ultrasound imager, see the movement, the flow and the heart rate.
