摘要
应用２４ｈ动态心电图以每小时房性早搏数（ＰＡＣ／ｈ）和室性早搏数（ＶＰＣ／ｈ）及复杂性室性心律失常发生率作为指标，对２２例高血压病孤立性室间隔肥厚患者、２０例高血压病向心型肥厚患者、２４例高血压病无左室肥厚患者及２０例正常对照者进行检测，结果发现，高血压病孤立性室间隔肥厚组与向心型肥厚组ＶＰＣ／ｈ及复杂性室性心律失常发生率较正常对照组和高血压病无左室肥厚组明显增加（Ｐ＜０．０５～０．０１）；而ＰＡＣ／ｈ的增加仅见于高血压病孤立性室间隔肥厚组（Ｐ＜０．０１）。表明：高血压病孤立性室间隔肥厚与向心型肥厚患者的室性心律失常和复杂性室性心律失常发生率均增高，前者房性心律失常的发生率也增高。
hour electrocardiographic recordings were evaluated in 20 healthy normotensive subjects, 24 hypertensive patients without left ventricular hypertrophy(LVH), 22 hypertensive patients with isolated septal hypertrophy(ISH)and 20 hypertensive patients with concentric LVH to determine the prevalence and complexity of cardiac arrhythmias. Ages,gender, body surface area and ejection fraction were similar in 4 groups.The results showed that prevalence and complexity of ventricular ectopic activity were significantly increased to a similar degree in hypertensive patients with concentric LVH and in those with ISH compared with normotensive subjects or hypertensive patients without LVH(P<0. 05～0. 01).The prevalence and complexity of atrial ectopic activity was only significantly increased in those with ISH(P<0. 01). Conclusion: Hypertensive patients with ISH had more ventricular and atrial arrhythmias than normotensive subjects and hypertensive patients without LVH.
