Syncope is a rapid onset, transient, loss of consciousness with a short duration. This symptom has been reported to be a specific presentation of patients with pulmonary embolism. However,...
This study was designed to validate the "San Francisco Syncope Rule". This set of rules was derived by Quinn et. al. to help guide the treatment of patients evaluated in the Emergency Dep...
Objective: To determine if atomoxetine 40 mg bid in patients ≥18 years old with recurrent vasovagal syncope will better prevent syncope during tilt testing than placebo.
OBJECTIVES: To evaluate syncope recurrence at follow up in patients with a positive cardio inhibitory response to the head up tilt testing (HUT) evaluation. METHODS: 36 consecutive patien...
Syncope affects about 50% of Canadians, is the cause of 1-2% of emergency room visits, and probably is responsible for CDN $250 million in health care spending each year.There is no known ...
Syncope is an unusual clinical manifestation of pulmonary embolism (PE), and the clinical significance of syncope in PE patients remains controversial. We investigated the incidence of syncope, examin...
We described the clinical evolution of patients with structural heart disease presenting at the emergency room with syncope. Patients were stratified according to their syncope etiology and available ...
Syncope and pre-syncope are well-known symptoms of acute pulmonary embolism (PE). However, data about their impact on short-term mortality are scant. We assess the short-term mortality (30-day) for al...
Emergency department (ED) visits for syncope are common. Validation of ED administrative diagnostic coding for syncope is required before these codes can be used for health services research. We perfo...
Syncope is a common condition that affects individuals of all ages and is responsible for 1-3% of all emergency department (ED) visits. Prospective studies on syncope are often limited by the exiguous...
One of the three polypeptide chains that make up the TROPONIN complex. It is a cardiac-specific protein that binds to TROPOMYOSIN. It is released from damaged or injured heart muscle cells (MYOCYTES, CARDIAC). Defects in the gene encoding troponin T result in FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.
One of the three polypeptide chains that make up the TROPONIN complex. It inhibits F-actin-myosin interactions.
One of the three polypeptide chains that make up the TROPONIN complex of skeletal muscle. It is a calcium-binding protein.
One of the minor protein components of skeletal muscle. Its function is to serve as the calcium-binding component in the troponin-tropomyosin B-actin-myosin complex by conferring calcium sensitivity to the cross-linked actin and myosin filaments.
A transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., BRAIN ISCHEMIA). Presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope.
