The following results were obtained in an experimental study in the dogs in general pentobarbital anaesthesia: Lidocaine type antiarrhythmics (lidocaine, Xylocaine ASTRA, Ethmozin USSR) administered shortly before artery ligation have a pro-fibrillation effect. This effect is indirectly proportional to the ischaemic focus development. A 3rd-generation beta blocker with intrinsic sympathetic activity (celiprolol, Selectol Chemie-Linz) had the same electrostabilizing effect on the ventricles in the acute phase of ischaemia as a 1st-generation beta blocker (metipranolol, Trimepranol SPOFA). The 3rd-generation blocker, however, stopped short of provoking a drop in the heart rate invariably associated with the 1st-generation beta blocker. The analgesic fentanyl (G. Richter) in combination with benzodiazepine (m,idazolam, Dormicum Hoffmann-La Roche) inducs analgosedation. In this way the dose of the analgetic can be reduced and yet the analgesia and electrostability of the heart remain the same. Due to the lower dose of the analgesic there is a lesser decrease in the heart rate and blood pressure. Analgosedation can be discontinued by administering an antagonist-agonist of benzodiazepines (flumazenil, Anexate Hoffmann-La Roche) or an antagonist of potent analgesics (butorphanol, Beforal SPOFA) without the risk of eliminating, at the same time, the electrostabilizing effect of analgosedation on the ischaemically damaged ventricles of the heart. For the prevention of sudden coronary death due to ventricular fibrillation in the acute phase of local myocardial ischaemia we can, on the basis of our experimental results, recommend analgosedation and the use of beta blockers with intristic sympathetic action. The use of lidocaine antiarrhythmics may lead to a reduction in the electric stability of the heart ventricles the ischaemic focus is developing under a certain "critical" blood level of the antiarrhythmics.
