WebYour heart contracts (beats) when it receives an electrical impulse from your sinoatrial (SA) node. This signal is called heart conduction. The SA node is your body’s “natural pacemaker,” setting your heart’s rhythm. Heart conduction continues as the electrical signal moves to the atrioventricular (AV) node in your right atria. WebThe sinoatrial node is located in the upper part of the right atrium in the healthy heart, and serves as the natural pacemaker (Figure 1). These nodal cells manifest spontaneous …

Bundle branches and … Heart rate depends on the rate at which the sinoatrial node produces action potentials. At rest, heart rate is between 60 and 100 beats per minute. This is a result of the activity of two sets of nerves, one acting to slow down action potential production (these are parasympathetic nerves) and the other acting to speed up action potential production (sympathetic nerves). Modulation of heart rate by ANS is carried by two types of channel: Kir and HCN (members of the CNG …
