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 a common reason for ED attendance and it presents a major management challenge with regard to the appropriate workup and disposition. Nearly 50% of patients are admitted, and for many this ...
Syncope is a common clinical presentation in emergency department. The diagnostic workup for syncope causes significant man-hour loss and expensive investigations. Most often the battery of investigat...
An implantable loop recorder (ILR) assists in the diagnosis of unexplained syncope and atrial fibrillation (AF). Both become prevalent with age. Limited data exist describing the incidence of AF as th...
Syncope could be related to high risk of falls and injury in adults, but documentation is sparse. We examined the association between syncope and subsequent fall-related injuries in a nationwide cohor...
Troponin measurement is one of crucial assessments facilitating diagnosis of acute coronary syndrome. Patients with chronic kidney disease are decimated by cardiovascular disease. Unfortunately, eleva...
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.
