Why the study?
Do nitroglycerin, post-extrasystolic potentiation, and their combination unmask asynergic residual contraction during ventriculography?
Do nitroglycerin, post-extrasystolic potentiation, and their combination unmask asynergic residual contraction during ventriculography?
Nitroglycerin, post-extrasystolic potentiation, and their combination are equally effective in unmasking residual contractile ability in asynergic ventricular zones during ventriculography.
No takes yet. Share an insight, caveat, or question.
Should not yet change ventriculography practice; hypothesis-generating for TNG or PESP to assess residual contractility in asynergic zones.
Banka et al. (1976) studied this question.
