目的:观察老年人支气管哮喘急性发作期与稳定期24小时动态心电图变化。方法:老年支气管哮喘患者76(男54,女22)例。年龄60~89(74±8)岁。哮喘病史2~31(12±9)年。哮喘发作期安放24小时动态心电图;稳定2周后再做24小时动态心电图。结果:哮喘发作期与稳定期24小时动态心电图中最高心率[(142±31)次/min vs.(113±17)次/min]、最低心率[(76±9)次/min vs.(54±11)次/min]、平均心率[(95±16)次/min vs.(73±13)次/min]、室上早次数[(353±72)次/24h vs.(92±37)次/24 h、室早次数[(327±75)次/24 h vs.(98±27)次/24 h]、室上速发生率(91%vs.20%)、房颤发生率(37%vs.16%)、ST-T改变发生率(78%vs.30%)和J波发生率(28%vs.5%)均显著增多或增高(P<0.05或P<0.01)。结论:哮喘发作期较稳定期可诱发多种心律失常和心电图改变。
Objective: To observe the change of 24 hours Holter bronchial asthma acute attack and stable electrocardiogram in elderly patients. Methods: Elderly patients with bronchial asthma 76 (male 54, female 22) cases. Age 60 ~ 89 (74 ± 8) years old. A history of asthma 2 ~ 31 (12 ± 9) years. 24-hour ambulatory asthma attack placed electrocardiogram; stable 24-hour ambulatory electrocardiogram after 2 weeks. RESULTS: The maximum heart rate in the 24 h Holter electrocardiogram during the asthma attack and stable phase was (142 ± 31) times / min vs. (113 ± 17) beats / min and the lowest heart rate was (76 ± 9) times / min vs. 54 ± 11) times / min, mean heart rate [(95 ± 16) times / min vs. (73 ± 13) times / min) 37) times / 24 h, the number of early ventricular [(327 ± 75) times / 24 h vs. (98 ± 27) times / 24 h], the incidence of supraventricular tachycardia (91% vs. 20% (P <0.05 or P <0.01), the incidence of ST-T change (78% vs 30%) and J wave incidence (28% vs.5% ). CONCLUSIONS: More stable asthma attacks can induce a variety of arrhythmia and ECG changes.
