Key result
Resetting from different right ventricular sites resulted in a site-dependent change in at least one characteristic of the resetting response in 12 (52%) of 23 ventricular tachycardias.
Why the study?
Does stimulation site influence the resetting response characteristics in patients with ventricular tachycardia?
Observational (n=23)
Does stimulation site influence the resetting response characteristics in patients with ventricular tachycardia?
Stimulation site-dependent changes in resetting responses suggest that human ventricular tachycardia circuits have a variable contribution of anatomic and functional characteristics.
No takes yet. Share an insight, caveat, or question.
Stimulation site may alter VT circuit assessment during resetting; leaves open effects on mapping or ablation strategies.
Callans et al. (1996) conducted an observational in Ventricular tachycardia (n=23). Resetting from different right ventricular sites (apex vs outflow tract) was evaluated on Site-dependent differences in the duration of the flat portion and the slope of the increasing portion of the resetting response. Resetting from different right ventricular sites resulted in a site-dependent change in at least one characteristic of the resetting response in 12 (52%) of 23 ventricular tachycardias.
