近几年来,随着电生理方法的日趋成熟和微电子学的迅速发展,快速性心律失常的电治疗也有了新的进展,它已成为80年代心脏起搏技术研究和应用的一个重要方面。快速心律失常系指各种规则的或不规则的伴有快速心率的非正常窦性心律。它们有的可能无明显的临床症状,如运动等原因所致的生理性心动过速;有的则可能由于快速心率导致血液动力学的改变和心肌氧耗量增加而诱发一系列的临床症状,甚至危及生命,
In recent years, with the maturation of electrophysiological methods and the rapid development of microelectronics, electrical therapy of tachyarrhythmia has made new progress. It has become an important aspect of the research and application of cardiac pacing technology in the 1980s. Tachyarrhythmia refers to a variety of regular or irregular abnormal sinus rhythm with rapid heart rate. Some of them may have no obvious clinical symptoms such as physical tachyarrhythmias such as exercise; others may induce a series of clinical symptoms due to hemodynamic changes caused by rapid heart rate and increased myocardial oxygen consumption, Even life-threatening,
