Table 2.

Values of examined parameters for studied groups (2nd, 4th, 6th columns) and statistical differences (p-value) obtained by Mann-Whitney test between MI patients with and without VT (3rd column), as well as between non VT MI patients group and control group (5th column).

NDC – non dipolar content of QRST integral maps, STT_DI – departure index of absolute value of STT integral map, STT_QRST_CORR – correlation coefficient between STT and QRST integral maps, TCRT – total cosine between QRS complex and T wave, Tpeak-Tend INT – T wave peak to T wave end interval, TSI_DI – departure index of absolute value of T-wave shape index, QRS INT – QRS interval, QT INT – QT interval, QT INT DISP – dispersion of QT interval, SD – standard deviation, and ns – not significant.
