[Clinical aspects of reperfusion arrhythmia following intravenous thrombolysis in acute myocardial infarct].

In accordance with the majority of the reports in the literature reperfusion arrhythmias were observed in more than 30% of the patients with acute myocardial infarction (n = 25) under or immediately after a highly dosed short-term infusion with streptokinase. With reference to indirect signs the recanalisation rate was assumed with 75%. Only one third of the reperfusion arrhythmias had haemodynamically significant characteristics and required an influence. Though in literature from animal experimental findings directive conclusions for the therapy are to be derived, the procedure in practice is still vastly empirical. In the ventricular tachycardia lidocaine, procainamide and ajmalin may be recommended. In ineffectiveness or particularly threatening situations the electrotherapy (cardioversion, DC-shock) is to be preferred. The concept inaugurated by Corr and Witkowski apply alpha-adrenoreceptor blockers has not yet entered the clinical practice. Possible problems in the treatment of reperfusion arrhythmias in the prehospital phase should at present still be a reason not to antedate the thrombolytic therapy into this phase.
