What Is The Heart's Secondary Pacemaker. It’s like a backup system. The contraction of cardiac muscle (heart muscle) in all animals is initiated by electrical impulses known as action potentials that in the heart are known as cardiac action potentials.

Web discovery health the heart actually has two natural pacemakers. Web pacemakers are commonly used to treat cardiac arrhythmias that cause a person's heartbeat to be too slow ( bradycardia ). For example, sick sinus syndrome and. Web in cardiology, a specialized cell or group of cells that automatically generates impulses that spread to other regions of the heart. Often, a pacemaker device can correct it. They make up the cardiac pacemaker, that is, the. The cells that create these rhythmic impulses, setting the pace for blood pumping, are called pacemaker cells, and they directly control the heart rate. Web a pacemaker is a small d evice used to treat some arrhythmias. It’s like a backup system. The rate at which these impulses fire controls the rate of cardiac contraction, that is, the heart rate.
The rate at which these impulses fire controls the rate of cardiac contraction, that is, the heart rate. For example, sick sinus syndrome and. It’s like a backup system. They can stabilize abnormal heart rhythms and prevent. The cells that create these rhythmic impulses, setting the pace for blood pumping, are called pacemaker cells, and they directly control the heart rate. Web the heart has its own pacemaker that regulates the rate at which it beats. But some hearts don't beat regularly, a problem called arrhythmia. The sinoatrial node (sa node) is the primary pacemaker and the atrioventricular node (av node) is the. Web a “secondary pacemaker” is any focal collection of heart muscle cells that has the ability to take over in case the primary pacemaker goes down. Web a pacemaker is a device that helps keep the heart beating regularly. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
