Key result
Programmed stimulation in 12 infarcted dog hearts demonstrated a direct relationship between V1V2 and V2T1 intervals, showing an inverse relationship is not a specific indicator of functional reentry.
Why the study?
Does the relationship between V1V2 and V2T1 intervals serve as a specific indicator of functional reentry in infarcted dog hearts?
Population
12 4-day-old infarcted dog hearts

Challenges specificity of inverse V1V2-V2T1 relationship for functional reentry; leaves open clinical translation in human VT.
Does the relationship between V1V2 and V2T1 intervals serve as a specific indicator of functional reentry in infarcted dog hearts?
An inverse relationship between the coupling interval of a premature impulse and the first tachycardia impulse is not a specific indicator of functional reentry in ventricular tachycardia.
Cabo et al. (1997) studied Reentrant ventricular tachycardia (n=12). Programmed stimulation (PES) was evaluated on Relationship between V1V2 and V2T1 intervals. Programmed stimulation in 12 infarcted dog hearts demonstrated a direct relationship between V1V2 and V2T1 intervals, showing an inverse relationship is not a specific indicator of functional reentry.
