Table 4.
Normal EGM | Abnormal EGM | Fractionated EGM | EGM with IP | |
---|---|---|---|---|
Bipolar amplitude (mV) | 5.33±2.71 | 1.39±0.77 | 0.32±0.16 | 0.16±0.22 |
Unipolar amplitude (mV) | 11.10±3.85 | 6.55±3.31 | 3.45±1.95 | 1.13±1.55 |
Transmurality (%) | 0.05±0.18 | 0.32±0.39 | 0.68±0.32 | 0.77±0.29 |
Width (ms) | 64.2±19.7 | 87.0±22.6 | 119.2±36.0 | 255.2±134.3 |
Abbreviations: as above. In each line, values were compared two by two. The p values are all <0.0001, except for transmurality: IP vs. fractionated (p = 0.002).
