Does extended external loop recorder monitoring improve diagnostic yield in patients with unexplained syncope or palpitations?
Extended external loop recorders provide a high diagnostic yield for unexplained palpitations and a moderate yield for syncope, suggesting they could be used as a stepwise approach before implantable loop recorders.
