Abstract
Syncope is a Total Loss of Consciousness (TLOC) due to cerebral hypo-perfusion, characterized by a rapid onset, short duration, and spontaneous complete recovery. It shares many clinical features with other disorders; it therefore presents in many differential diagnoses. This group of disorders is labeled TLOC. TLOC is a state of real or apparent LOC with loss of awareness, characterized by amnesia for the period of unconsciousness, abnormal motor control, loss of responsiveness, and a short duration. The clinical features characterizing TLOC are usually derived from history taking from patients and eyewitnesses. When a patient first presents with possible TLOC, history taking should first establish whether there was indeed a TLOC. Often, this allows a distinction between the major TLOC groups. The cornerstone of management of these patients is non-pharmacological treatment, including education, lifestyle modification, and reassurance regarding the benign nature of the condition. The aim of the present study was to determine the etiologies and the age distribution of patients with syncope in Delta area. This study was carried out at the department of cardiology Tanta University Hospitals. Thirty patients were included in this study. This study was done over a period of six months from September 2019 until February 2020. The main results of the study revealed that: Most frequent risk factors syncope was hypertension (57%), followed by diabetes mellitus (40%), coronary artery disease (16%), chronic kidney disease (6%), cardiomyopathy (3%), valvular heart disease (3%) Most frequent symptoms of patients with syncope was dizziness (34%), followed by palpitation (24%), shortness of breath (24%), syncope (24%), chest pain (16%), easy fatigability (3%) Most common ECG rhythm in patients presented with syncope was normal sinus rhythm (58%), complete heart block (24%), left ventricular hypertrophy (6%), Slow AF (3%), LBBB (3%), ventricular tachycardia (3%) Regarding our study, the most common diagnosis of syncope was vasovagal syncope (42%), idiopathic syncope (31%) then cardiac syncope (15%) that includes CHB (6%), VT (3%), and slow A. Fib. (6%), lastly orthostatic hypotension and neurological causes (6% each) The incidence of idiopathic syncope in populations under 40 years was significantly higher than in populations over 40 years (p = 0.0001), meanwhile regarding cardiac-related etiology for syncope in patients under age 40 was significantly lower than those patients over age 40 (p = 0.0001).
