Key result
Localized nontransmural necrosis altered epicardial potential maps, with the direction of missing positivity correlating well with average fiber direction in the necrotic mass (r=0.82, p<0.01).
Effect estimate: r = 0.82
p-value: p=<0.01

May refine epicardial mapping in necrotic regions; leaves open translation to human arrhythmia mapping.
Watabe et al. (1990) studied Nontransmural necrosis (n=13). Localized nontransmural necrosis vs. Controls was evaluated on Correlation between the direction of missing positivity and average fiber direction in the necrotic mass (r = 0.82, p=<0.01). Localized nontransmural necrosis altered epicardial potential maps, with the direction of missing positivity correlating well with average fiber direction in the necrotic mass (r=0.82, p<0.01).
