Bae, Moon, Kwon, Jang, Lee, Lee, Yoo, Rhee, and Lee: Signal Averaged Electrocardiography Using Holter Tape in Patients without Heart Disease

Abstract

Background

Ventrlcular tachyarrhythmias are major cause of sudden cardiac death in patients after myocardial infarction and their accurate detection seems to be important in prevention of sudden cardiac death. Clinical findings, treasmill test, holter monitoring and coronary angiography have been used to search for high risk group in sudden cardiac death. Recently electrographysiologic stimulation has been to this, but it is not practical, because of high cost and invasiveness. Signal averaged electrocardiogram(SAECG) may be helpful in prediction of high risk group in sudden cardiac death. So we try to know the values of SAECG in Korean patients without heart disease.

Results

1) The mean value and standard deviation of Time domain analysis is as follows ; fQRS : 106.8±12.3ms, RMS : 36.2±21.5(micro)V, LAS : 27.2±8.1ms. 2) The mean value and standard deviation of Spectral turbulence analysis is a follows ; LSCR : 58.6±3.9, ISCM : 95.2±0.8, ISCSD : 71.8±15.7, SE : 6.9±1.8.

Conclusion

There was no significant difference between male and female. Time domain analysis shows significant differences among each hour but spectral turbulence analysis did not. Spectral turbulence analysis shows high specificity.
