The heart, a four-chambered muscular pump, uses alternating contraction (systole) and relaxation (diastole) to circulate blood through the pulmonary (lungs) and systemic (body) circuits, maintaining a normal heart rate (sinus rhythm).<\/p>\n\n\n\n<p><strong>Cardiovascular Anatomy<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Heart Location and Structure:<\/strong>&nbsp;Located in the thoracic mediastinum, the heart weighs 250-350g and is enclosed in the&nbsp;pericardium, a protective sac.

It spontaneously generates the initial electrical impulse (60\u2013100 times per minute) that triggers the heartbeat.<\/li>\n\n\n\n<li><strong>Atrial Conduction<\/strong>: The signal spreads across both atria, causing them to contract and push blood into the ventricles. This activity is visible as the&nbsp;<strong>P wave<\/strong>&nbsp;on an ECG.<\/li>\n\n\n\n<li><strong>Atrioventricular (AV) Node<\/strong>: Situated between the atria and ventricles, this node acts as a&nbsp;<strong>gatekeeper<\/strong>. It briefly delays the signal (approx. 120ms) to ensure the atria have completely emptied their blood before the ventricles contract.<\/li>\n\n\n\n<li><strong>Bundle of His<\/strong>: After the delay, the impulse travels through this bundle of fibers located in the interventricular septum. It is the only electrical bridge between the atria and the ventricles.<\/li>\n\n\n\n<li><strong>Bundle Branches<\/strong>: The Bundle of His splits into&nbsp;<strong>left and right branches<\/strong>, which carry the signal toward the apex (bottom) of each respective ventricle.<\/li>\n\n\n\n<li><strong>Purkinje Fibers<\/strong>: These fine fibers spread rapidly through the ventricular walls. They trigger a synchronized, powerful contraction of the ventricles, pumping blood to the lungs and the rest of the body.
