1

reentrant ventricular tachyarrhythmias are defined by what ECG morphology?

3 consecutive QRS complexes originating in the ventricles and recurring at a rapid rate

2

what is the most common mechanism for reentrant ventricular tachyarrhythmia?

reentry (micro or macro)

3

reentrant ventricular tachyarrhythmia is most often associated with what condition?

ischemic heart disease

4

reentrant ventricular tachyarrhythmias can be easily confused with what condition?

aberrantly-conducted SVTs

5

is VT regular?

yes

but, can degenerate to V fib (irregular)

6

what are the QRS morphologies favoring VT?

tall R in V1
deep S save in V6

7

what is the ECG appearance of ventricular flutter?

sine wave
