Patho U3 Dysrhythmias Exam With Complete
Solutions 100% Verified!!
dysarhythmia/arrhythmia - ANSWER>>disturbance of a heart rhythm
-the conduction suite, controls the rhythm of the heart
myocardial cells have - ANSWER>>potential initating and conducting impulses
pacemaker cells generate - ANSWER>>generate impulses at a raster rate and the cells
of the conduction system transmit impulses faster as well
what controls heart rhythm - ANSWER>>the conduction system
conduction system - ANSWER>>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 - ANSWER>>SA node
-intrinsic rate = 60-100
, if SA node fails. - ANSWER>>AV node assume pacemaker
-intrinsic rate = 40-60
purkinje system can. - ANSWER>>assume pacemaker function of the ventricles if the
AV junction fails to conduct impulses from atria to ventricle
--intrinsic rate ~15-40
P wave - ANSWER>>depolarization of the atria
-LUB
PR interval - ANSWER>>delay of AV node to allow filling of ventricles
QRS - ANSWER>>ventricular depolarization
-DUB
T wave - ANSWER>>ventricular repolarization
normal ECG rhythm - ANSWER>>P wave
PR interval
QRS
T wave
atrial fibrillation ECG - ANSWER>>P rate >300
No PR interval
QRS variable
Rhythm irregular ("regularly irregular")
