摘要
Incessant ventricular tachycardia and "electrical storms" are emergencies, requiring urgent action in a close cooperation between critical care physicians and cardiologists. The leading cause of such events is advanced cardiac disease. Besides the patient's history, an ECG and, if applicable, an implantable cardioverter-defibrillator (ICD) interrogation is required for a reliable diagnosis. Further diagnostics include laboratory parameters, an echocardiogram, and possibly a coronary angiography. The medical therapy, consisting of amiodarone and beta-blockers, should immediately be initiated after diagnosis. In the case of failed drug therapy, urgent catheter ablation is indicated. This is a complex procedure, in which the clinical tachycardia or the electrical substrate is modified by using an irrigated catheter. The acute success rate of this life-saving procedure is high. However, there might also be complications due to the required extensive procedures.
