Coronary artery ligation in pigs induced acute ischemia, where local conduction delay correlated linearly with giant R wave amplitude (r = 0.81 at 8 minutes).
Effect estimate: r = 0.81
p-value: p=<0.0001
In a porcine model of acute transmural myocardial infarction, the development of a giant R wave is directly correlated with local conduction delay.

Associates giant R waves with conduction delay in porcine ischemia; leaves open relevance for human MI risk stratification.
Chang et al. (1989) studied Acute transmural myocardial ischemia (n=30). Coronary artery ligation vs. Nonischemic state / control amplitude was evaluated on Correlation between local conduction delay and local R wave amplitude (r = 0.81, p=<0.0001). Coronary artery ligation in pigs induced acute ischemia, where local conduction delay correlated linearly with giant R wave amplitude (r = 0.81 at 8 minutes).
