Question 1
During an EP study, programmed atrial extrastimulation reproducibly initiates a tachycardia only when a critical AH-interval prolongation ('jump') occurs. This finding is most characteristic of which arrhythmia?
Correct Answer:
Typical AVNRT (slow-fast)
Question 2
A ventricular extrastimulus delivered during supraventricular tachycardia when the His bundle is refractory (His-synchronous) advances the next atrial activation. What does this prove?
Correct Answer:
An accessory pathway is present
Question 3
During SVT, ventricular entrainment produces a post-pacing interval (PPI) minus tachycardia cycle length (TCL) of less than 115 ms and a corrected VA interval that is short. These findings most support which mechanism?
Correct Answer:
Orthodromic AVRT
Question 4
On cessation of ventricular overdrive pacing that entrains an SVT with 1:1 VA conduction, the atrial electrograms return in a 'V-A-V' response. This excludes which diagnosis?
Correct Answer:
Atrial tachycardia
Question 5
What is the normal range for the HV interval measured during an electrophysiology study?
Correct Answer:
35-55 ms
