The origin of ventricular tachycardia lies in the ventricular tissue and includes a variety of symptoms such as monomorphic and polymorphic ventricular tachyarrhythmia (VT), ventricular flutter and ventricular fibrillation. Due to transitions of one form of VT to another, any form of VT incurs in principal the risk of cardiac failure. Apart from different electrophysiologic mechanisms such as reentry or triggered activity, any occurrence of VT has to be considered in an individual context: VT can be caused by structural heart disease such as coronary artery disease or dilative cardiomyopathy, or primary electrical disease such as long or short QT syndromes or can even occur without any detectable cause (idiopathic VT). Correct identification of the underlying cause of the arrhythmia is essential for the prognosis, differential therapy and long-term treatment of patients.
室性心动过速起源于心室组织，包括多种症状，如单形性和多形性室性快速心律失常（VT）、心室扑动和心室颤动。由于一种VT形式可转变为另一种形式，任何形式的VT都主要存在心力衰竭风险。除了折返或触发活动等不同的电生理机制外，任何VT的发生都必须在个体背景下考虑：VT可由结构性心脏病如冠状动脉疾病或扩张型心肌病引起，或由原发性电疾病如长QT综合征或短QT综合征引起，甚至可在无任何可检测到的病因（特发性VT）的情况下发生。正确识别心律失常的潜在病因对于患者的预后、鉴别治疗和长期治疗至关重要。
