The Research On The Correlationship Between Tcm Syndromes And Heart Rate Variability In Elderly Primary Hypertension

Objective:To study the correlation between TCM syndromes and heart rate variability in elderly primary hypertension.Methods:This study was applied in the way of designing questionnaire, using four diagnostic methods to collect the condition information of each patient and filling the questionnaire, with which the diagnose of TCM syndromes was in line.24 hours sinus heart rate was recorded through dynamic ECG recording, and standard deviation of all N-N intervals in 24 h (SDNN), standard deviation of the 5-min average of N-N intervals in 24 h (SDANN), root mean square of successive N-N interval difference in 24 h (RMSSD) and percentage of successive N-N intervals more than 50ms (PNN50) were calculated by automatically analysis software of heart rate variability, and the calculations were filled in the questionnaire. Artery blood pressure in patients'arm was measured by using a mercury column sphygmomanometer, and the survey databases were filled in the questionnaire. Then each index was separately analyzed by using SPSS 17.0 package.Results:1. The percentage of live-fire hyperactivity in TCM syndromes of elderly primary hypertension was 17.05, excessive phlegm-dampness was 36.36, yin-yang deficiency was 17.05 and yin deficiency and yang hyperactivity was 29.55.2. The difference of HRV in the male and female with elderly primary hypertension showed no statistically significance (p>0.05).3. The value of SDNN SDANN RMSSD and PNN50 in elderly primary hypertension with 2 level of blood pressure are higher than that of 1 level of Blood pressure and the difference has statistically significance (p<0.01); that of 3 level are higher than that of 2 level and the difference has statistically significance (p<0.01);4. The value of SDNN SDANN RMSS5D and PNN50 in elderly primary hypertension with live-fire hyperactivity are higher than that of yin deficiency and yang hyperactivity and the difference has statistically significance (p<0.05); that of yin deficiency and yang hyperactivity are higher than that of yin-yang deficiency and the difference has statistically significance (p<0.05); but these above differences between excessive phlegm-dampness and live-fire hyperactivity have no statistically significance (p>0.05).Conclusion:1. The main TCM syndromes of elderly primary hypertension are excessive phlegm-dampness and yin deficiency and yang hyperactivity.2. Sex differences in elderly primary hypertension did not affect heart rate variability.3. The degree of heart rate variability of elderly primary hypertension is increased with the increase of blood pressure.4. Some indicators of heart rate variability make role of diagnose of parts of TCM Syndromes of elderly primary hypertension.
