What is a pacemaker? What is happening in a heart with arrhythmia? Why might I need a pacemaker? What symptoms could these conditions cause?. Web. A biventricular pacemaker is implanted in the chest, and it connects to three thin wires, called leads. The leads go into different chambers of your heart. If there is a problem with your heartbeat, the pacemaker sends a painless signal through the leads to fix the problem. The pacemaker also can speed up your heart if it is beating too slowly. However, keep in mind the pacemaker is rate-responsive, meaning it will increase the rate of your heart in response to your activity level. So, for example, if you are exercising, the pacemaker will be able to stimulate the heart to beat more quickly in order to pump blood efficiently. Web.

A healthy heart has a natural pacemaker called the sinus node that is one of the principal elements of the cardiac conduction system, which controls the heart rate. It generates electrical impulses which move throughout the heart muscle and stimulate the heart to contract and pump blood. If you have been diagnosed with an arrhythmia (irregular. The heart has a natural "back-up" pacemaker that can generate a pulse and control the heart rate. To say it is a study by the University of Manchester that has identified the Sap (the subsidiary atrial pacemaker) able to take the place of the sinoatrial node, which is the main way in which the heart generates electrical signals that make it. Dual-chamber pacemakers are used to treat arrhythmias that affect both chambers of the heart. Biventricular pacemakers.

Web. Web. Web. Web. Web. Web. Web. The normal pacemaker of the heart is the sinoatrial node (SA node) situated in the upper part of right atrium (upper chamber of the heart). It gives out regular electrical pulses to the heart at a rate between 60 - 100 per minute. These pulses are conducted down the right atrium to the atrioventricular node (AV node, situated at the junction. Pacemaker surgery is done to implant a pacemaker device. A pacemaker is comprised of a pulse generator that houses a battery and circuitry, as well as one to three small electrical leads that are placed in the chambers of the heart. Each electrical pulse emitted by the pacemaker stimulates a heartbeat and is timed to ensure a normal heart rhythm.
