2-3% of emergency department (ED) syncope patients suffer arrhythmia/death within 30-days of disposition (either as inpatient or at home) and the investigators recently developed the Canadian Syncope Arrhythmia Risk Score (CSARS) to predict these outcomes. Currently, only holter monitoring is used and is applied a few days later. New and innovative remote (out-of-hospital) external cardiac monitoring technology has made prolonged monitoring possible with live automatic and patient triggered cardiac rhythm transmission to a central monitoring station.
