A pacemaker is a small device to help control your heartbeat and is placed in your chest under the skin. Its use is to enable the heart to beat more regularly in case you have an irregular heartbeat (arrhythmia), particularly a slow one. It is implanted in your chest through a surgical procedure.

Types of pacemakers-

Depending on your condition, you might have one of the following types of pacemakers.

Single chamber type

This type usually carries electrical impulses to the right ventricle of your heart.

Dual-chamber type 

Using this, electrical impulses are carried to the right ventricle and the right atrium of your heart to help control the contraction-timing between the two chambers.

Biventricular type

Biventricular pacing, also called cardiac resynchronization therapy, is for people with heart failure with abnormal electrical systems. This type of pacemaker stimulates the lower chambers of the heart (the right and left ventricles) to make the heartbeat more efficiently.

AtaCor Medical, a startup founded in 2014, is developing an implantable pacemaker with the lead implanted in the tissue above the heart. The best part is it doesn’t require any leads to be placed inside or on the heart.
