观察了187例高血压病(EH)患者24 h动态心电图(DCG)的心律失常变化,187例 EH 患者心律失常的发生率随着年龄递增及高血压分期的增加而增加。年龄小于60岁的室性心律失常检出率为43.48%,大于70岁者检出率为75.00%。EH 者Ⅰ期室性心律失常检出率为34.80%,而Ⅲ期检出率为75.00%。合并左室肥厚(LVH)者,室性心律失常检出率较无 LVH 者为高。分别为64.70%与44.85%。伴有 ST 段改变者室性心律失常较无 ST 段改变者为高,分别为51.28%与50.0O%。高血压是心血管病的独立危险因素,当其合并LVH 及伴有 ST 段改变,则心律失常发生率增高,尤其为室性心律失常,这将导致心脏事件的发生。因此应积极防治 EH,以减少心律失常及 LVH 等发生,防止或避免心脏事件的出现。
The changes of arrhythmia of 24 hours ambulatory electrocardiogram (DCG) in 187 patients with essential hypertension (EH) were observed. The incidence of arrhythmia in 187 patients with EH increased with the increase of age and the increase of hypertension stage. The detection rate of ventricular arrhythmia of less than 60 years old was 43.48%, while the detection rate of more than 70 years old was 75.00%. EH who Ⅰ ventricular arrhythmia detection rate was 34.80%, while the detection rate of Ⅲ was 75.00%. Patients with left ventricular hypertrophy (LVH), ventricular arrhythmia detection rate was higher than those without LVH. Respectively 64.70% and 44.85%. Ventricular arrhythmias with ST-segment changes were higher than those without ST-segment changes, accounting for 51.28% and 50.0%, respectively. Hypertension is an independent risk factor for cardiovascular disease. When combined with LVH and ST segment changes, the incidence of arrhythmia is increased, especially ventricular arrhythmia, which will lead to cardiac events. Therefore, EH should be actively controlled to reduce arrhythmia and LVH and other occurrences, to prevent or avoid the occurrence of cardiac events.
