窦性心律不齐在正常人群中的分布规律

Distribution Patterns of Sinus Arrhythmia in Normal People in China

目的探讨窦性心律不齐在我国正常健康人群的分布规律。方法在健康体检人群中随机选取302例无临床症状的窦性心律不齐健康者为统计对象,对其心电图资料统计分析。结果窦性心律不齐在16～30岁占88.08%（266/302）,31～55岁占11.92%（36/302）;窦性心率在70bpm以下的心率段共占94.70%（286/302）,其中60bpm以下占70.86%（214/302）,71～90bpm的心率段共占5.30%（16/302）,而90bpm以上未见到1例（为0例）。结论窦性心律不齐在30岁以下的青年健康人群与70bpm以下的心率段中比较常见,尤其是窦性心动过缓中更是如此,随着年龄和窦性心率的增加而逐渐减少或消失,呈现出明显的年龄和心率趋势。

Objective To discuss the distribution patterns of sinus arrhythmia in normal people in China. Methods Taking the 302 cases without the symptom of sinus arrhythmia selected randomly from the health check - up people as the target of statistics, a statistical analysis has been carried out respectively on electrocardiograph（ECG）. Results Sinus Arrhythmia was seen 88. 08% （266/302） at the age of 16 to 30 and 11.92% （36/302） at the age of 31 to 55. And 94. 70% （286/302） was seen in the sinus heart rate below 70bpm,70. 86% （214/302） was seen below 60bpm,5.30% （16/302） was seen in the sinus heart rate 71 -90bpm, none was seen above 90bpm. Conclusion Sinus arrhythmia, especially sinus bradycardia is more commonly seen in the heath young people under 30 and those sinus heart rate below 70bpm. Sinus arrhythmia gradually decreases or disappears with the aging and the going up of the heart rate,which distinct a strong age and heart rate trend.
