Paroxysmal atrial fibrillation detection in patients with acute ischemic stroke through prolonged Holter: prospective study.

In elderly patients with AIS, the use of an extended Holter recorder led to the detection of more cases of PAF, offering them the chance to initiate hypocoagulant therapy. Among this population, the STAF score was non-discriminative and did not prove useful in predicting PAF.
