The effects of the combined administration of β‐adrenoceptor antagonists and non‐steroidal anti‐inflammatory drugs on ligation‐induced arrhythmias in rats

1 Pretreatment of anaesthetized rats with intravenously administered β‐adrenoceptor antagonists or non‐steroidal anti‐inflammatory drugs (NSAIDs) reduced the incidence and severity of ventricular arrhythmia which resulted from acute coronary artery ligation. 2 The β‐adrenoceptor antagonists preferentially suppressed the immediate (Phase 1A) arrhythmia while the NSAIDs suppressed the delayed (Phase IB) arrhythmias. 3 Combined administration of β‐adrenoceptor antagonists and the NSAIDs produced a more pronounced antiarrhythmic effect than either of the drugs alone.
