Two patients with intractable life-threatening ventricular tachycardias have been studied using intracardiac electrograms and programmed electrical stimulation of the heart. Both patients have shown to have an underlying re-entry mechanism in the ventricles as the basis for the tachycardias. Both patients underwent epicardial mapping studies at cardiac surgery, and the site of re-entry was established. In one patient the re-entry front was found to start in the posterobasal region of the left ventricle and in the other patient the re-entry front was found in the anterobasal region of the right ventricle. In both patients surgical interruption of the re-entry front was carried out. Both patients are alive and free from tachycardias at the time of writing.
我们使用心内电图和心脏程控电刺激对两名患有顽固性危及生命的室性心动过速的患者进行了研究。两名患者均显示心室存在潜在的折返机制,这是心动过速的基础。两名患者均在心脏手术时进行了心外膜标测研究,并确定了折返部位。在一名患者中,发现折返前沿始于左心室后基底区域,而在另一名患者中,折返前沿位于右心室前基底区域。两名患者均进行了折返前沿的手术阻断。在撰写本文时,两名患者均存活且无心动过速发作。
