Abstract

The role of the autonomic nervous system in facilitating the occurrence of malignant ventricular arrhythmias is supported by several experimental and clinical observations [1]. In different animal models it has been demonstrated that sympathetic activation, particularly during acute myocardial ischemia, may alter cardiac electrical properties and increase electrical instability [1–3]. In the clinical setting, indirect signs of sympathetic activation such an increase in heart rate, are frequently observed in the minutes preceding the onset of ventricular tachycardia or fibrillation [4].
