dysarhythmia/arrhythmia - CORRECT ANSWERS disturbance of a heart rhythm


-the conduction suite, controls the rhythm of the heart


myocardial cells have - CORRECT ANSWERS potential initating and conducting impulses


pacemaker cells generate - CORRECT ANSWERS generate impulses at a raster rate and the
cells of the conduction system transmit impulses faster as well


what controls heart rhythm - CORRECT ANSWERS the conduction system


conduction system - CORRECT ANSWERS SA node (rhythmic impulse generated)
-intranodal pathways (SA to AV)
-AV node (impulse from atrial delayed before passing to ventricle)
-AV bundle (impulse from atria to ventricle)
-Purkinje system
-R/L bundle branch
-L anterior and posterior fascicle


primary pacemaker - CORRECT ANSWERS SA node
-intrinsic rate = 60-100


if SA node fails... - CORRECT ANSWERS AV node assume pacemaker
-intrinsic rate = 40-60

purkinje system can.. - CORRECT ANSWERS assume pacemaker function of the ventricles if
the AV junction fails to conduct impulses from atria to ventricle
--intrinsic rate ~15-40


P wave - CORRECT ANSWERS depolarization of the atria
-LUB


PR interval - CORRECT ANSWERS delay of AV node to allow filling of ventricles


QRS - CORRECT ANSWERS ventricular depolarization
-DUB


T wave - CORRECT ANSWERS ventricular repolarization


normal ECG rhythm - CORRECT ANSWERS P wave
PR interval
