Abstract:
Objective To investigate the effect of 24h Holter monitoring in patients with asymptomatic myocardial ischemia diagnosis. Methods 80 patients with asymptomatic myocardial ischemia in coronary heart disease(CHD)were detected by 24h Holter monitoring,and the results were recorded. Results In 80 patients of CHD myocardial ischemia occurred in 75 cases,accounting for 93.75%,and ischemic ST segment depression appeared total of 824 matrix times,and in each case there were 1 to 23 matrix times,an average of 8.3,and the average ST segment depression was(0.15±0.06)mV; Most of asymptomatic myocardial ischemia occurred in the daytime,and the peak onset occured in 6 to 12 hours; High and low heart rate was positively correlated with the degree of ischemia,and faster heart rate was,more obvious ST segment depression was down,more serious myocardial ischemia was induced. Conclusion 24h Holter monitoring of asymptomatic myocardial ischemia condition assessment and early prevention is important.
