Discover the fascinating journey of the heart’s electrical impulses! Learn how the sinoatrial (SA) node, the heart’s natural pacemaker, initiates the rhythm that spreads to the atrioventricular (AV) node, ensuring synchronized contractions. Perfect for medical students looking to master cardiac electrophysiology with ease!

31K views · 361 reactions | #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 | Facebook

The electrical signal normally travels from the SA node → AV node → ventricles. In a heart block, that pathway becomes delayed or blocked — leading to bradycardia, dropped beats, or complete loss of atrial-ventricular communication.
