Relationship between Quantitative T-wave Alternans Estimates and Parameters Describing Clinical Status of Patient in Accute Phase of Myocardial Infarction and Outcome Results

Relationship between parameters describing clinical status of the patient in acute phase of myocardial infarction, outcome results and quantitative estimates of T-wave alternans, known prognostic factor of severe cardiac arrhythmias or sudden cardiac death, was investigated in aim to reveal their usefulness and incremental diagnostic utility. Integrated estimate, reflecting differences between S-T,T complexes of odd and even cardiocycles, obtained by means of Principal Component Analysis showed significant correlation with Left Ventricular Ejection Fraction and rehospitalization of patient within 6 months.
