Electrocardiographic monitoring in ambulatory patients with cardiac arrhythmias.

abstract：:Syncope is a common but complex medical disorder with a multitude of etiologies, some of which are still not well understood. In a general population, the greatest diagnostic yield is from the history and physical examination. Numerous other diagnostic modalities include Holter monitoring, signal-averaged ECG, cardiac...
