What are the 6 parts of the cardiac conduction cycle? correct answer: -SA node -Internodal pathways -AV node -Bundle of His -R and L bundle branches -Purkinje fibers What is the SA node? correct answer: -Small cluster of cells located in the upper R atrium *-Pacemaker of the heart* What are internodal pathways? correct answer: Impulses sent by the SA node that travel through the atrial muscle fibers via the intra-atrial pathways Allows for simultaneous depolarization and contra...

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...

NUR 425 Exam 1 Questions and Answers | Latest Update | 2024/2025 | Already Passed 1st degree AV block -Prolonged PR interval -One QRS for every P wave -Same distance between each QRS, same distance between every P wave 2nd degree AV block (Type I: Wenkebach) -PR Intervals get progressively longer with each heart beat -QRS may drop (Longer, longer, longer, drop) 2nd degree AV block (Type II) -Heart beat occasionally loses QRS complex -Lonely P waves with no QRS 3rd degree AV ...

Which statement is correct regarding premature ventricular complexes (PVCs)? PVCs originate from the atrium. PVCs may be unifocal or multifocal in origin. PVCs will not lead to ventricular tachycardia. PVCs only originate from one site in the ventricles. - PVCs may be unifocal or multifocal in origin. A regular rhythm at a rate of 40-60 beats per minute, with narrow QRS complexes, and no visible P waves, is consistent with the presence of: atrial fibrillation. sinus bradycardia. juncti...

Which rhythm is demonstrated if the heart has lost all electrical activity? Asystole, Idioventricular, Pulseless electrical activity (PEA), Ventricular fibrillation correct answers Asystole What period of time defines a sustained ventricular tachycardia? 2 seconds 30 seconds 120 seconds 300 minutes correct answers 30 seconds Why is the R-on-T premature ventricular complex (PVC) of major concern? The ventricles are depolarizing early during the repolarization phase The ventricles are ...
