Pacemakers of the Heart correct answer: Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV nod...

What is Arrhythmia? Abnormally with: Speed (bradycardia vs. tachycardia) OR Rhythm: Origin (sinus vs atrial vs ventricular) Describe the Conduction pathway? 1) Electrical impulses begin at the SA node - under vagus nerve control: parasympathetic and then travel down to the AV node 2) AV node's refractory period acts as a "gate" to prevent excessive impulses from being conducted into the ventricles 3) From the AV node, the impulses then travel to the bundle of HIS 4) Action potentials sp...
