#Sinoatrial (SA) node #arrhythmias, also known as sinus node dysfunction or sick sinus syndrome, occur when the heart's natural pacemaker (SA node) doesn't function properly, leading to abnormal heart rhythms. These arrhythmias can include slow heart rates (bradycardia), fast heart rates (tachycardia), or a combination of both, potentially causing symptoms like lightheadedness, dizziness, and fatigue. #education #ECG #doctor #medicalstudent #nurses | Med G

Follow 👉🏻Dimax Life Sciences The Pacemaker of the Heart: SA Node The Sinoatrial (SA) Node, located in the upper wall of the right atrium, is known as the natural pacemaker of the heart. It generates electrical impulses that initiate the heartbeat, setting the rhythm and rate of cardiac contractions. These impulses spread across the atria, causing them to contract and push blood into the ventricles. The SA node ensures the heart beats in a regular, rhythmic pattern, typically at 60-100 beats pe
