Adrenergic System and Ventricular Arrhythmias in Acute Myocardial Ischemia: Multiple Feedback Mechanisms

  • G. Heusch
Conference paper


Myocardial ischemia is essentially a hemodynamic situation, i.e., an inadequate blood supply to the myocardium, which is characterized by secondary consequences such as regional myocardial dysfunction, counter-regulatory reflexes, and, of course, ventricular arrhythmias. It is therefore the purpose of this presentation to focus on hemodynamic mechanisms and emphasize the multiple feedback loops between acute myocardial ischemia, sympathetic reflexes, and ventricular arrhythmias (Fig. 1).
