Reentrant ventricular tachyarrhythmias Flashcards
1
Q
reentrant ventricular tachyarrhythmias are defined by what ECG morphology?
A
3 consecutive QRS complexes originating in the ventricles and recurring at a rapid rate
2
Q
what is the most common mechanism for reentrant ventricular tachyarrhythmia?
A
reentry (micro or macro)
3
Q
reentrant ventricular tachyarrhythmia is most often associated with what condition?
A
ischemic heart disease
4
Q
reentrant ventricular tachyarrhythmias can be easily confused with what condition?
A
aberrantly-conducted SVTs
5
Q
is VT regular?
A
yes
but, can degenerate to V fib (irregular)
6
Q
what are the QRS morphologies favoring VT?
A
tall R in V1
deep S save in V6
7
Q
what is the ECG appearance of ventricular flutter?
A
sine wave
