Abstract

Objectives: Syncope is defined as a sudden and transient loss of consciousness followed by complete spontaneous recovery. This study describes the syncope evaluation in patients referred to the Heart Clinic.

Methods: This descriptive cross-sectional study was conducted on 60 syncope patients referred to Afshar Heart Clinic of Yazd, Iran, from September 2016 to March 2017. After performing clinical workups, the etiology of syncope was diagnosed in each patient. Electrocardiography and blood pressure measurements were done for all patients. Additional clinical tests, including echocardiography, Holter Monitoring, Head-Up tilt table test (HUTT), electroencephalography, and Magnetic Resonance Imaging, were performed for some patients based on the cardiologist's opinion. The distribution of patient's clinical records, such as age, sex, diabetes, hypertension, history of ischemic heart disease (IHD), duration of syncope, postdrome, prodromal symptoms, and clinical test results according to causes of syncope in patients, were reported.

Results: Sixty patients with a mean age of 50.7 ± 20.4 years were evaluated (55% male). Thirty-five patients (58.3%) had Neurally Mediated Syncope, 18 patients (30%) had arterioventricular (AV) Block induced syncope, and 7 (11.7%) patients had Sick Sinus Syndrome (SSS) induced syncope. Age, hypertension, prodromal symptoms, history of IHD, ECG, Holter monitoring, and HUTT results were associated with the cause of the syncope.

Conclusions: Cardiac syncopes (AV-Block induced and SSS induced) were related to older age, hypertension, abnormal electrocardiogram, and abnormal Holter monitoring results. Neurally mediated syncope was associated with younger age, prodromal symptoms, and abnormal HUTT results.
