Cardiac pacemaker - Wikipedia

WebNov 20, 2008 · Answer : When a pacemaker is pacing the heart, in most circumstances, the patient is unaware of the tiny electrical impulse that is delivered to the heart to pace it. So in most instances, you do not feel an electric shock or any indication that electrical activity is being delivered. WebApr 30, 2024 · Sensors on the tip of the catheter apply heat (radiofrequency energy) to the heart tissue at the AV node and destroy the electrical signaling connection. Once the AV node is destroyed, your doctor implants a pacemaker, unless you already have one. You will need the pacemaker for the rest of your life. After WebThe rate at which these impulses fire controls the rate of cardiac contraction, that is, the heart rate. The cells that create these rhythmic impulses, setting the pace for blood pumping, are called pacemaker cells, and they directly control the heart rate. They make up the cardiac pacemaker, that is, the natural pacemaker of the heart. dorking wanderers youth fc
