Paroxysmal supraventricular tachycardia and the risk of ischemic stroke.

ABSTRACT:

Background and purpose

It is unknown whether supraventricular arrhythmias other than atrial fibrillation or flutter are associated with stroke.

Methods

To examine the association between paroxysmal supraventricular tachycardia (PSVT) and stroke, we performed a retrospective cohort study using administrative claims data from all emergency department encounters and hospitalizations at California's nonfederal acute care hospitals in 2009. Our cohort comprised all adult patients with ≥ 1 emergency department visit or hospitalization from which they were discharged alive and without a diagnosis of stroke.
