title: Effect of quinidine together with antibiotics on contractility of cat papillary muscle.
abstract: The extent of depression of myocardial contractility produced by the combination of quinidine and gentamicin, tetracycline, or amphotericin B was found, in an in vitro model, to be no greater than that due to the more active drug alone.
