An artificial pacemaker is an electronic device which sends out electrical impulses to the sinoatrial node (SA node) located in the right atrium to mimic the heart’s natural pacemaker. It is used to prevent the heart from beating abnormally and treats problems related to the rate/rhythm of the heartbeat. Basically, it’s a generator made up of a battery and a computer circuitry housed in a metal casing. Conventional pacemaker (with wires) casing is implanted under the skin in the upper chest or shoulder region. Its wires are threaded through the veins of the shoulder and guided into the heart with the help of X-rays. Once the wires are positioned in the heart they are hooked up to the generator. On the other hand, the wireless (leadless) pacemaker is a very small device which can be placed directly inside the patient’s heart. To understand ‘tiny leadless pacemaker’ it’s essential to be adequately aware of the heart’s electrical system.
