Abstract

Ventricular ectopic activity occurred only after premature atrial beats in a patient with an acute inferior wall myocardial infarction. The ventricular ecbopic activity occurred only when the coupling interval between the premature atrial beats and preceding sinus beat was ≤0.44 s. The sinus cycle length, however, appeared to influence the form of expression of ventricular ectopic activity independent of coupling intervals, with single premature ventricular contractions occurring at cycle lengths ≥0.72 s, couplets at cycle lengths of 0.68 to 0 71 s, and ventricular tachycardia at cycle lengths ≤0.67s.
