Fig. 2From: PR interval prolongation in coronary patients or risk equivalent: excess risk of ischemic stroke and vascular pathophysiological insightsKaplan-Meier Survival Curves for New-Onset Cardiovascular Events by PR Prolongation. Patients with PR prolongation >200 ms had significantly reduced survival from a cardiovascular death (log rank: 14.4, P < 0.001); b Ischemic Stroke (log rank: 8.7, P = 0.003); d CHF (log rank: 5.0, P = 0.026) e Combined Cardiovascular Endpoints (log rank: 14.2, P < 0.001). PR interval > 162 ms was associated with reduced survival from c new-onset MI (log rank: 7.4, P = 0.007)Back to article page
