Adapta With MVP Pacing System


Some people have very slow heart beats or slow pulse. If this slow pulse is caused by medicines, these medicines may be stopped. However, sometimes your doctor may not be able to stop the medicine because it is essential for conditions such as high blood pressure or coronary artery disease or some types of arrhythmias. Sometimes the slow heart beat persists even after all medicines are stopped. In these situations, patients need help to increase the speed of their heart. This is frequently done by a minor surgery known as Implantation of a PERMANENT PACEMAKER.

A Pacemaker is a small metal box usually the thickness of 2-3 quarters stacked on top of each other. The box contains a battery and a small computer, which can be programmed externally with a small computer called a programmer. It is placed under the skin in the upper part of your chest, just under the collar bone. It has 1 or 2 wires going from the pacemaker, through a vein, into the various chambers of your heart. The surgery usually takes 30 minutes to 1 hour to perform, and is done in a hospital. Most people spend 1 night in the hospital afterwards. Usually you will be required to not drive a car for 2 weeks, and to not raise your arm above the shoulder level for 4-6 weeks. Afterwards, your cardiologist will check the pacemaker battery and wires every 6 months, with the help of a computer and and wand, in their office. Most pacemaker batteries last > 5 years, after which it needs to be changes out by another minor surgery.

What exactly can a pacemaker do?

A pacemaker prevents your heart from going too slow. A pacemaker cannot control fast heart beats. To control fast heart beats or tachycardia, you generally need medicines or ablations or both.
