The search for silent atrial tachyarrhythmias remains one of the cornerstones in patients suffering from embolic stroke of undetermined source.

The search for silent atrial tachyarrhythmias remains one of the cornerstones in patients suffering from embolic stroke of undetermined source. We report the case of a 76-year-old female patient suffering from recurrence of ischemic stroke, adequately selected based on the presence of predictors of atrial fibrillation (AF), to perform prolonged ECG monitoring. This recording allowed to document long-last-ing AF triggered by atrial tachycardia. It was also possible to demonstrate a direct correlation between AF and new cerebral stroke.

Automated summary

The search for silent atrial tachyarrhythmias is crucial in patients with embolic stroke of undetermined source. We present a case of a 76-year-old female patient with recurrent ischemic stroke, who underwent prolonged ECG monitoring based on predictors of atrial fibrillation (AF). The monitoring revealed long-lasting AF triggered by atrial tachycardia and a direct correlation between AF and new cerebral stroke.
