目的探讨室早指数对器质性病变患者发生恶性室性心律失常的预测价值。方法106例经动态心电图诊断为窦性心律伴发室性心律失常的患者,分为器质性与非器质性病变两组,统计室早个数、室速和室颤的发作阵次及诱发室速、室颤的室早联律间期、室早前次心搏的QT间期。结果106例患者中,平均24h室早总数12066±1105个;阵发室速662±79次,53例由RonT室早诱发,其中器质性病变46例(86.85%);阵发室颤39±5次,均发生于器质性病变者,其中11例(68.8%)由快速多形性室速诱发;器质性与非器质性病患者中诱发室速和(或)室颤的室早联律间期分别为340±15ms和420±20ms,室早前次心搏的QT间期分别为420±10ms和410±25ms,室早指数分别为0.90±0.10和1.00±0.15,两组比较有显著性差异(p<0.05)。结论当室早指数在0.78～0.83之间时,易诱发阵发性室速和室颤,尤其是器质性病变者,临床应给予足够的重视和治疗。
Objective To investigate the predictive value of ventricular antebracho-index for the occurrence of malignant ventricular arrhythmia in patients with organic disease. Methods One hundred and six patients with sinus rhythm and ventricular arrhythmia diagnosed by ambulatory electrocardiogram were divided into two groups: organic and non-organic lesions, the number of early statistical room, the onset and incidence of ventricular tachycardia and ventricular fibrillation Ventricular tachycardia, ventricular fibrillation, ventricular tachycardia, ventricular tachycardia QT interval. Results Among the 106 patients, the average number of patients was 12066 ± 1105 in the early 24 hrs. The mean duration of paroxysmal VT was 662 ± 79. Among them, 53 patients were induced early by RonT, including 46 organic lesions (86.85%), paroxysmal VF ± 5 times, all occurred in organic lesions, of which 11 cases (68.8%) were induced by rapid pleomorphic VT; in patients with organic or non-organic disease induced VT and / or ventricular fibrillation The early intercourse interval was 340 ± 15 ms and 420 ± 20 ms, respectively. The QT interval of the second heart beat was 420 ± 10 ms and 410 ± 25 ms respectively, and the premature ventricular index were 0.90 ± 0.10 and 1.00 ± 0.15, respectively There was significant difference (p <0.05). Conclusion When the early index is between 0.78 and 0.83, it is easy to induce paroxysmal VT and ventricular fibrillation, especially those with organic diseases. Clinical should be given enough attention and treatment.
