Basic ECG Interpretation (100% Verified Answers)

Basic ECG Interpretation correct answers -Normal conduction system = *electrical impulses* -Components of an ECG complex -Determining rate & regularity -Measuring intervals (PR, QRS & QT) -*Identify*: Normal Sinus Rhythm, Sinus Bradycardia, Sinus Tachycardia & Sinus Arrythmia & Treatment for each Cardiac Conduction correct answers -based on automaticity( ability of heart cells to spontaneously generate an action potential) -conductivity (ability for cardiac cells to transmit action potential from one cell to another -Rhythmicity (ability for cardiac cells to spontaneously generate an action potential at a regular rate sinoatrial (SA) node correct answers pacemaker of the heart -located in the right atrium -lower action potential threshold than other cells atrioventricular node correct answers "gatekeeper" -accepts all atrial action potentials right and left bundle branch (RBB) correct answers -L&R BB acts as anchor His bundle correct answers Sits on the atrioventricular septum -delayed for a few moments Purkinje fibers correct answers forces volume of blood up from apex of heart inherent rates correct answers -*SA Node*: 60-100 beats/min -if SA node is damaged or blocked, AV node takes over -*AV node*: 40-60 beats/min -if AV node is damaged, than purkinje fibers maintain rate -*Purkinje Fibers*: 15-40 beats/min P wave correct answers atrial depolarization (contraction) -SA node is firing
