QuestionAnswer
electrical impulses discharged from cardiac cells outside the SAN ectopic
PVC premature ventricular contraction
VPC ventricular premature contraction
blood flow during a PVC stops
characteristics of a PVC include the QRS complex being wide and bizarre and different
characteristics of a PVC usually include the absence of a P wave
characteristics of a PVC usually include a T wave in the opposite direction compared to the QRS complex
characteristics of a PVC usually include the R to R interval being doubled
PVCs with uniform morphology are called unifocal premature ventricular contractions
PVCs with different morphology are called multifocal premature ventricular contractions
PVC with an R wave that lands on the T wave of the preceding cardiac cycle R on T phenomenon
two PVCs in immediate succession couplet or pair
three or more PVCs in immediate succession run
succession one after another
PVC occuring every second cardiac cycle bigeminy
PVCs occuring every third cardiac cycle trigeminy
PVCs occuring every fourth cardiac cycle quadrigeminy
PVCs must be reported immediately if two occur in immediate succession couplet or pair
PVC must be reported immediately if three or more PVCs occur in immediate succession run
it is important to state the number of PVCs in the run
PVCs must be reported immediately if its R wave lands on the T wave of the preceding cardiac cycle R on T phenomenon
PVCs must be reported immediately if they have different morphology multifocal
PVCs must be reported immediately if there are more than six per minute
ventricular tachycardia is a tachyarrhythmia caused by ectopic electrical impulses originating in the ventricles
ectopic displaced
characteristics of V-tach the distance between R waves is consistent which means the rhythm is regular
characteristics of V-tach usually include a heart rate of 150 - 250 beats per minute
characteristics of V-tach usually include the absence P waves
characteristics of V-tach usually include QRS complexes greater than 0.12 of a second
VT with a heart rate less than 150 bpm slow ventricular tachycardia
VT with a heart rate greater than 250 bpm ventricular flutter
VT must be reported immediately because it can quickly transition to a chaotic life threatening arrhythmia abbreviated VF ventricular fibrillation
ventricular fibrilation means the heart is twitching instead of contracting
VF causes blood flow to stop
VF is a chaotic life threatening arrhythmia
VF lasting four to six minutes can cause brain death
characteristics of VF usually include the absence of p waves
characteristics of VF usually include the absence of QRS complexes
characteristics of VF usually include the absence of a heart rate
two types of VF include coarse ventricular fibrillation
two types of VF fine ventricular fibrillation
VF requires immediate implementation of a code blue
implementation put into effect
idioventricular rhythm is an indication of a sign dying heart
agonal rhythm has a heart rate less than 40 bpm
AIVR accelerated idioventricular rhythm
AIVR heart rate is greater than `40 bpm
AIVR has absence of P waves
AIVR has complexes greater than 0.12 of a second
asystole means an absence of cardiac electrical activity represented by a straight line
Asystole ventricular standstill or flatline
Asystole means the heart is not contracting
Asystole causes blood flow to stop
Asystole requires immediate implementation of a code blue
code blue cardiopulmonary arrest
application of a controlled electric shock to the heart to arrest life threatening arrhythmias defibrillation or electrical cardioversion
