Table 2 Incidence of early repolarization and characteristics among study group and control group

From: Early repolarization with horizontal ST segment may be associated with aborted sudden cardiac arrest: a retrospective case control study

  Sudden cardiac arrest Control p value
Early repolarization (inf+lat) n, (%) 5 (20) 4 (6.7) p = 0.116
J-point elevation of >2 mV, n (%) 4 (16) 1 (1.7) p = 0.025
ER with horizontal ST 5 (20) 2 (3.3) p = 0.021
ER with ascending ST 0 (0) 2 (3.3) p > 0.05
Distribution of ER    
Inferior lead, n (%) 4 (16) 1 (1.7) p = 0.025
Lateral lead, n (%) 1 (4) 3 (5) p = 1.0
