HOAG ECG EXAM QUESTIONS AND ANSWERS 2026 EDITION
110-250 - ANSWER vtach rate
0.36-0.44 - ANSWER typical QT interval
500 - ANSWER QT high limit
QT interval - ANSWER indicates the entire length of depolarization and
depolarization of phases
HR: The shorter the QT interval, the higher the ()
Three medications that raise QTI are haldol, tikosyn, and amiodarone.
atrial pacing - ANSWER spike appears right before p
ANSWER spike appears immediately prior to QRS in ventricular pacing.
atrial and ventricular pacing - ANSWER spike happens before and after p
Dual chamber pacing, often known as atrial and ventricular pacing,
1st letter - ANSWER indicates which chamber will be paced
2nd letter - ANSWER specifies which chamber is sensed by the pacemaking
3rd letter - ANSWER pacemakers response to monitoring the patients natural
heart activity
100% of the time, the AOO- ANSWER pacemaker mode paces in the atria. No
sensing capability. (post-op cardiac surgery or valvular surgery in presence of
AV block)
When natural atrial activity is detected, the AAI- ANSWER pacemaker mode
paces the atria and stops pacing if it happens. (Sinus node dysfunction with
