1st degree av block Study guides, Class notes & Summaries

1st degree AV Nodal Block - the AV node is having difficulty getting the action potentials on through to the rest of the conduction system. See prolonged PR intervals 2nd degree AV Nodal Block - there is even more difficulty than in first degree. 3rd degree AV Nodal Block - even more serious than second degree. See many Ps without QRS complexes, AP not getting through at all A bands - contain mainly thick filaments Abstract memory - Type of Explicit memory, Fact memory ( learning facts, li...

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...
