A cardiac event monitor may be helpful in patients with transient symptoms or palpitations to exclude other rhythms such as ventricular tachycardia.
There is normal conduction in the His bundle, and the His-ventricular interval is normal.
Preceding each QRS, there should be a His bundle depolarization
AV conduction is variable
VA conduction is variable
Junctional tachycardia other diagnostic studies
Pulseless ventricular tachycardia other diagnostic studies
Second degree AV block other diagnostic studies
Third degree AV block other diagnostic studies
First degree AV block other diagnostic studies
Atrioventricular block other diagnostic studies
Ventricular tachycardia other disgnostic tests
Wide complex tachycardia risk factors
