How Does a Pacemaker Work?

Is your physician contemplating pacemaker insertion to regulate your heart rate? At Cardiovascular Institute, cardiologist, Dr. Daljit Muttiana, provides this life-changing device for qualified patients in the Tomball, TX, area.

Just what is a pacemaker?

A pacemaker is an implantable electronic device which monitors heart rate, function and vital signs such as blood pressure and respiratory rate. Millions of people in the United States experience improved cardiac function and peace of mind as they live with this small wonder which resides under the skin in the chest--typically near the collarbone.

Cardiovascular Institute in Tomball, TX, features an on-premises pacemaker clinic. It aids Dr. Muttiana's patients in interpreting pacemaker information and in modifying treatments accordingly.

How does it work?

Heart rhythm is regulated by a small bit of natural electrical tissue called the sinoatrial mode located at the top of the heart. As it sends an impulse through the heart, upper and lower chambers pump blood through the body. In a normal heart, the chambers are fully coordinated and respond to increasing and decreasing bodily activity.

For the abnormal heart, a pacemaker must take over or assist in several cardiac functions. The device itself has two electrical leads, or sensors, which touch the heart. A generator and battery provide the electrical impulses.

The National Heart, Blood and Lung Institute outlines several functions which implantable pacemakers, and their on-board computers, accomplish:

Why would you need a pacemaker?

People with significant heart damage due to heart attack, congenital malformation or heart failure often benefit from the insertion of a pacemaker. Demand pacemakers speed up slowed or irregular heartbeats. Rate responsive pacemakers react to how active you are--speeding up or slowing down your heart as needed. Your pacemaker may be equipped with a cardioverter defibrillator to stimulate the heart to beat in the event of a cardiac arrest.
