Abstract

Syncope is a common problem encountered in cardiology consults that can be due to various causes, ranging from benign to life-threatening conditions. The role of the consultant is to risk stratify the patient in order to guide the treatment and prevent long-term morbidity and mortality. This is primarily achieved by identifying or excluding an underlying cardiac etiology. Identifying the cause of syncope allows for proper management which significantly improves the quality of the patient’s life and prevents injury to the patient or others.
