摘　　要：目的了解校正QT离散度（QTcd）对高血压病室性。心律失常的影响。方法检查98例高血压病患者24小时动态心电图、心电图校正QT离散度及超声心动图。结果左室肥厚组68例，其中17例（25％）出现Lown2b级以上室性早搏，其中QTcd≥60ms者16例（94.1％）；非左室肥厚组30例，其中4例（13.3%）出现Lown2b级以上室性早搏（P＞0.05），其中QTcd≥60ms者3例（75％）；两组中QTcd＞60ms者Lown2b级以上室性早搏发生率明显高于QTcd＜60ms者。结论高血压病人QTcd延长，其室性早搏发生率增加。To explore the effects of corrected QT dispension(QTcd) on patients with arrhythmiacaused by hypertention. Meteal:98 cases with essential hypertension were studies by Holier, QTcd of gram and echocardiogram. Results: There were 68 cases with left ventricular hupertophy(LVH), among which 17 cases had lown ventricular arrythmia at ahave 2 b(25% ), among which 16 cases' QTcd were beyond 60ms (94. 1% ).There were 30 cases with non-LVH, among which 4 cases had lown ventricular arrhythmia at above 2b, (P>0. 05 ),among which 3 cases' QTcd were beyond 60ms (75%). In the two groups,those cases whose QTcd were beyond60ms had a higher rate of ventricular extrasystole than those whose QTcd were below 60ms. Conclusion: The longer theQTcd is in the cases with hypertension, the higher rate the ventricular extrasystoleis.
