FAQs
What are the four main functions of the heart? The heart generates pressure, ensures one-way flow via valves, regulates cardiac output, and releases atrial natriuretic peptide (ANP).
What is the role of the SA node? The SA node is the natural pacemaker; it generates electrical impulses at 60-100 per minute to start each heartbeat.
Why is the AV node delay important? The delay of about 0.1 second allows the atria to contract completely before the ventricles contract, ensuring efficient blood filling.
