Here's exactly what happens every time your heart beats 🫀 It starts with an electrical signal from the SA node — your heart's natural pacemaker. That signal tells your atria to contract, pushing blood down into the ventricles. Then the ventricles contract (ventricular systole): 🫀 Right ventricle → pumps deoxygenated blood to the lungs 🫀 Left ventricle → pumps oxygen-rich blood to the rest of your body After that, the heart enters diastole — a brief relaxation where the chambers refill and pre

⚡ How Does the Heart Keep Beating in Rhythm? ⚡ The heart's conduction system is a network of specialized cells that generate and transmit electrical impulses, making your heart beat in a steady rhythm. It starts with the sinoatrial (SA) node, the heart's pacemaker, which triggers the electrical signal. This signal travels through the atrioventricular (AV) node, the Bundle of His, and Purkinje fibers, causing the heart’s chambers to contract in a coordinated manner. Together, they ensure the hear

🫀 Heart Blocks A heart block happens when there’s a delay or interruption in the electrical conduction that controls the heart’s rhythm. Here are the 4 types you need to know: 🔹 1st Degree → PR interval is prolonged 🔹 2nd Degree Type I (Wenckebach) → PR gets progressively longer, then drops a beat 🔹 2nd Degree Type II (Mobitz II) → PR is consistent, but some QRS complexes are randomly dropped ⚠️ Highest risk of progressing to 3rd degree 🔴 3rd Degree (Complete Heart Block) → No communication
