分析老年前期８２例、老年期１２４例高血压病患者和健康老年前期４６例、老年期６３例的２４小时动态心电图心律失常特点。结果显示老年前期高血压组总房性心律失常和总室性心律失常发生率分别为９０．２％和５９．８％，老年高血压组分别是９８．４％和７５．０％，差异显著（均Ｐ＜０．０１）；老年前期对照组分别为８０．４％和４５．７％，与同期高血压组比较差异不显著（均Ｐ＞０．０５）；老年对照组分别为８７．３％和５２．３％。与同期高血压组比较差异显著（均Ｐ＜０．０１）。老年高血压组中伴左室肥厚（ＬＶＨ）者（６６例）其总室性心律失常和Ｌｏｗｎ’ｓ分级≥３级室性心律失常发生率分别是８４．８％和３６．４％，均高于不伴ＬＶＨ者（５８例）的６３．８％和１３．８％（Ｐ＜０．０１）。在老年前期高血压组中伴ＬＶＨ者其Ｌｏｗｎ’ｓ分级≥３级室性心律失常发生率为１９．０％，高于不伴ＬＶＨ者的２．５％（Ｐ＜０．０５）．提示室性心律失常的发生与ＬＶＨ密切相关。
The characteristics of 24-hour ambulatory electrocardiogram arrhythmia in 82 pre-senile patients, 124 elderly hypertensive patients, 46 healthy pre-senile patients and 63 senile senile patients were analyzed. The results showed that the incidence of total atrial arrhythmia and total ventricular arrhythmia were 90.2% and 59.8% in the elderly prehypertensive group and 98.4% and 75.0% in the elderly hypertensive group, respectively, with significant difference (All P <0.01). The pre-senile control group was 80.4% and 45.7% respectively, which was not significantly different from that of hypertension group (all P> 0.05). The elderly control group was 87%. 3% and 52.3%. Compared with the same period of hypertension group significant difference (all P <0.01). The incidences of total ventricular arrhythmia and Lown’s grade ≥3 ventricular arrhythmia in elderly hypertensive patients with left ventricular hypertrophy (LVH) were 84.8% and 36.4%, respectively Higher than those without LVH (58 cases) 63.8% and 13.8% (P <0.01). In the prehypertensive group with LVH, the incidence of Lown’s grade ≥3 ventricular arrhythmia was 19.0%, which was higher than 2.5% of those without LVH (P <0.05). Prompted the occurrence of ventricular arrhythmias and LVH are closely related.
