Question

What kind of signal does a cardiac pacemaker use?

1) Electrical
2) Chemical
3) Mechanical
4) Sound

Answer 1

Cardiac pacemakers use electrical signals to regulate the heartbeat by delivering impulses to the heart muscles, which assists in correcting arrhythmias.

Step-by-step explanation:

The kind of signal a cardiac pacemaker uses is electrical. A cardiac pacemaker is a medical device that delivers electrical impulses to the heart muscles to regulate the heartbeat. This helps in maintaining an adequate heart rate, especially in cases where the heart's natural pacemaker is not functioning properly. The electrical signals it provides ensure the heart beats at a normal rate and helps treat arrhythmias, which are problems with the rate or rhythm of the heartbeat.
