WebThe Sino atrial node helps in the transmission of an electrical signal to the heart. This causes the contraction of the heart muscle. The signal that is generated is known as the pace making signal also known as the pacemakers. This signal travels through the right atrium followed by the atrioventricular node and then to the ‘Bundle of His’. WebThe Sino atrial node helps in the transmission of an electrical signal to the heart. This causes the contraction of the heart muscle. The signal that is generated is known as the …
WebDec 7, 2024 · An electrocardiogram — abbreviated as EKG or ECG — measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This electrical wave causes the muscle to squeeze and pump blood from the heart.

Webout the heart via specialized conducting tissue (Fig 1) and into the heart muscle. The electrical impulse results in mechanical contraction of the cardiac muscle through a series of intracellular events involving calcium. Figure 1. Electrical conduction within the heart starts at the sinoatrial (SA) node and passes sequentially to the ... WebEach beat of your heart begins with an electrical signal from the sinoatrial node, called SA node. The signal is generated as the two vena cavae fill your heart’s right atrium with blood from other parts of your body. The signal spreads across the cells of your heart’s right and left atria. This signal causes the atria to contract.
