- W2394296023 abstract "To investigate the associtation of heart rate variability with myocardial ischemia we observed the 24 h dynamic electrocardiogram in 35 cases of coronary heart disease. Heart rate variability was obtained statistically by a measure of the standard deviation of the set of all R-R intervals in a 24 h period while myocardial ischemia was estimated by the total time of the myocardial ischemia attack recorded in the 24 h dynamic electrocardiogram. The 35 patients were divided into high and low standard deviation group (high group standard deviation50 ms ,low standard deviation≤50ms). 22 patients were in high group and 13 patients were in low group. Comparison was made between the 2 groups in the number of transient myocardial ischemia attack and the total time of the myocardial ischemia in a 24 h period. The study showed significant differences existed between the 2 group both in numbers and in the total time of transient myocardial ischemic attack (P0. 01,P0.05). Negative correlation of low degree was observed between heart rate variability and total ischemic time (r=-0.29 , P0. 05 ). Significant difference could also be seen between the 2 groups in the numbers of nonsustained ventricular tachycardia (P0. 05). Our study indicated that low heart rate variability associated with myocardial ischemia and might be predisposed to serious arrhythmia." @default.
