Valsalva termination of ventricular tachycardia in myocardial infarction.

A 66-yr-old patient with recurrent monomorphic ventricular tachycardias subsequent to a previous myocardial infarction is reported. The tachycardia could repeatedly be terminated by the Valsalva manoeuvre. Procainamide, infused shortly before, possibly had an additional effect. As far as we know, this is the first report of ventricular tachycardias, as a result of an old myocardial infarction, that could be terminated by the Valsalva manoeuvre.
