ARC Preliminary Review Set #2 EDIT

The _____  is the time measured from the beginning of the QRS complex to the end of the T-wave.

The  _____  represents the repolarization (visible) of the ventricles.

_______  is the time required for the signal to propagate across the AV node (end of P-wave to beginning of QRS complex).

In First Degree AV Block, the PR interval is ____.

Depending on the block in Atrial Flutter, the rhythms may be regular or ______ .  This is in contradistinction to classic Atrial Fibrillation where the rhythm is ALWAYS irregular.

Second degree AV block Mobitz II is characterized by a  _____  PR interval when the P-Wave is conducted.  The other P-waves are simply not conducted.

Second degree AV block Mobitz I (Wenckebach) is characterized by a ____  of the PR interval until a P-wave is dropped.

“R on T phenomena”refers to a time when an electrical stimulus can strike the latter portion of the T-wave in the “vulnerable period” (when the ventricles are hypersensitive).  This might trigger _______  and possible sudden death.  Hence, a PVC during this time is particularly dangerous.

The treatment mode for a patient in Ventricular Fibrillation is IMMEDIATE _______.
