通过心导管记录左右心室内膜电位或手术时作心表和心内腹标测,可确定室速的起源部位,以便对致死性室速进行心肌切开、心内膜切除及冷冻凝固术等外科疗法。术前依据心电图、体表电位图和心向量图等非创伤性检查推测室速起源部位,可缩短创伤性检查和术中的标测时间,对手术成功有着重要作用。本文回顾17例19例次室速发作,根据术中标测或心导管检查确定的室速起源部位,探讨12导联心电图QRS波形与室速起源部位的关系。
Through the catheterization of left and right ventricular endocardial potential or ventricular endocardial surgery when the heart and abdominal markers measured to determine the site of origin of ventricular tachycardia in order to ventricular fatal ventricular tachycardia, endocardial resection and cryosurgery Surgical treatment. Preoperative based on the ECG, surface potential maps and cardiac vector maps and other non-invasive test speculated that the origin of ventricular tachycardia, can shorten the traumatic examination and intraoperative mapping time, the success of the operation has an important role. This article reviews 17 cases of 19 cases of sub-ventricular tachycardia episodes, according to intraoperative or cardiac catheterization to determine the origin of ventricular tachycardia to explore the 12-lead ECG QRS waveform and the relationship between the origin of ventricular tachycardia.
