Odds Ratio: 6.32 (95% CI 1.11–18.92)
p-value: p=.042
Prolonged non-invasive cardiac monitoring detects occult paroxysmal atrial fibrillation in nearly 25% of patients with cryptogenic stroke, with frequent PVCs and multiple DWI signals serving as strong predictors.

Supports prolonged monitoring to detect occult AF in cryptogenic stroke; leaves open effects on recurrence and need for RCTs.
Bhatt et al. (2011) conducted an observational in Cryptogenic stroke or TIA (n=62). Presence of PVCs lasting more than 2 minutes vs. Absence of PVCs lasting more than 2 minutes was evaluated on Detection of paroxysmal atrial fibrillation (PAF) (OR 6.32, 95% CI 1.11-18.92, p=.042). Prolonged non-invasive cardiac monitoring detected occult paroxysmal atrial fibrillation in 24% of patients with cryptogenic stroke or TIA, with PVCs lasting >2 minutes strongly predicting its presence (OR 6.32).
