Risk for atrial fibrillation in patients with hypertrophic cardiomyopathy assessed by signal averaged P wave duration

摘要

Conclusions-Measurement of P wave duration in sinus rhythm by high resolu- tion signal averaged electrocardiography may be a useful non-invasive clinical tool for identifying patients with HCM likely to develop electrical instability and atrial fibrillation. Objective-To assess the relation between P wave duration and the occurrence of Atrial fibrillation in hypertrophic cardio- Myopathy (HCM). Design-High resolution signal averaged Electrocardiography was used in 110 Patients with HCM to determine whether Patients at risk for paroxysmal atrial fib- Rillation could be detected during sinus Rhythm by measuring P wave duration.
