Unadjusted Kaplan Meier estimates of proportions of individuals with left anterior fascicular block free of atrial fibrillation, congestive heart failure, or death.
Differences in proportions are compared using log-rank tests. Individuals with left anterior fascicular block more often developed atrial fibrillation (p<0.001), congestive heart failure (p<0.001), and death (p<0.001), when compared to those without conduction disease.
