Table 2 Distribution of HRT category in the three groups

From: Ambulatory ECG-based T-wave alternans and heart rate turbulence can predict cardiac mortality in patients with myocardial infarction with or without diabetes mellitus

  Post-MI Post-MI + DM Group control P value
  (N = 96) (N = 77) (N = 75)  
Category 0 42* 32 * 63 P < 0.05.
Category 1 34* 27* 11 P < 0.05.
Category 2 20* 18* 1 P < 0.05.
  1. * Post-MI or post-MI + DM patients vs group control, P < 0.05
