在心肌梗塞急性期发生原发性室颤的72例患者中,作者对室上性早搏致室性心律失常的作用进行了研究。27例中男61例、女11例,平均年龄为59±11岁。全部病人均在胸痛发生后24小时内入院,平均4小时后到CCU病房,连续心电图监护4—108小时,平均32±28小时。72例中共记录到原发性室颤152次,其中6例(8％)患者由室上性早搏共诱发12次室颤及16次持续性或非持续性室速.共16次室速或室颤由单个室上性早搏诱发,12次由连续≥2个
In 72 patients with acute VF during the acute phase of myocardial infarction, the authors studied the effects of supraventricular premature beats on ventricular arrhythmias. There were 61 males and 11 females in 27 cases, with an average age of 59 ± 11 years. All patients were admitted within 24 hours after the occurrence of chest pain, an average of 4 hours to CCU ward, continuous ECG monitoring 4-108 hours, an average of 32 ± 28 hours. 72 cases of primary ventricular fibrillation were recorded 152 times, of which 6 (8%) patients induced by supraventricular premature beats a total of 12 times ventricular fibrillation and 16 cases of sustained or non-sustained ventricular tachycardia. A total of 16 ventricular tachycardia or Ventricular fibrillation induced by a single supraventricular premature beats, 12 times by a continuous ≥ 2 months
