High resolution ECG and heart rate variability

This study compares different new and traditional methods of high resolution ECG (HRECG) and heart rate variability (HRV) analysis in order to compare their efficacy and to improve the reliability of high risk stratification. From 26 cardiac patients after myocardial infarction (MI) and 35 healthy persons 30 minutes high resolution ECG's were analyzed. The HRV presents an important contribution in high risk stratification. HRECG, however, produces false positive results in about 18%. Applying discriminant function techniques on the parameter combination of the HRECG and HRV analysis improves the accuracy of separation between normal and pathological.
