目的探讨动态心电图对阵发性房性心动过速的诊断意义。方法分析63例伴有心脏疾患发生房性心动过速者,与24例无心脏器质性疾患发生的房性心动过速者作对照,观察房性心动过速发生的昼夜节律并统计短阵性房性心动过速的频率和持续时间、与发作相关的房性期前收缩的偶联间期。结果本文检出阵发性房性心动过速者87例为11.3%,心脏病组63例检出率为13%,对照组24例检出率为8.4%(χ2=42.8,P<0.001)。2组差异有非常显著意义。患者房性心动过速以右心房性发生率为高。心脏病组房性心动过速时发作的阵数、房速率、及持续时间与对照组比较差异均有统计学意义而发作时联律差异无统计学意义;昼夜节律变化在心脏病组不明显而在对照组明显。结论动态心电图检测对阵发性房性心动过速的临床诊断、指导治疗和评价疗效有重要意义。
Objective To investigate the significance of ambulatory electrocardiogram in the diagnosis of paroxysmal atrial tachycardia. Methods 63 cases of atrial tachycardia with heart disease were analyzed and compared with 24 cases of atrial tachycardia without heart disease, and the circadian rhythm of atrial tachycardia was observed and the short array The frequency and duration of atrial tachycardia, and the interventricular septal phase associated with the onset of atrial premature contractions. Results The detection rate of paroxysmal atrial tachycardia was 11.3% in 87 cases and 13% in 63 cases of heart disease. The detection rate of 24 cases in control group was 8.4% (χ2 = 42.8, P <0.001) . There are significant differences between the two groups. Patients with atrial tachycardia with a high incidence of atrial. Cardiac disease atrial tachycardia seizures when the number of atrial fibrillation, and duration of the control group were statistically significant differences in the onset of association law was no significant difference; circadian rhythm changes in the heart disease group was not obvious In the control group obvious. Conclusion Holter monitoring of paroxysmal atrial tachycardia clinical diagnosis, guidance and evaluation of the efficacy of great significance.
