1] Syncope or presyncope
usually occurs during long-term standing or after a change from the supine or sitting position to the upright position, accompanied by a significant decline in blood pressure (BP) and/or bradycardia.
North American and European specialists with experience in pediatric exercise testing describe the clinical applicability of pediatric exercise tests; conducting them; the testing procedure and its measurement variables; and practical approaches to complaints commonly seen in the exercise testing lab, such as congenital and acquired heart disease, exercise-induced dyspnea, chest pain with exercise, presyncope
and syncope with exercise, and exercise fatigue, as well as special populations: children with pectus excavatum, obesity, intellectual disability, and neuromuscular disease.
and profound bradycardia due to lithium toxicity.
Testing was symptom limited and was terminated if subjects reported limiting symptoms of dyspnea, fatigue, chest pain or for medical reasons including horizontal or down-sloping ST-segment depression ([greater than or equal to] 1 mm), ST segment elevation ([greater than or equal to] 1 mm in non-Q wave lead), atrial fibrillation, or supraventricular tachycardia, suggestive left bundle branch block, fall in systolic blood pressure ([greater than or equal to] 20 mm Hg), variation in diastolic pressure under stress higher than 15 mmHg, presyncope
, severe arrhythmias, presence of extra systoles, ataxia or ventricular ectopy (presence of 6 or more premature ventricular b x [min.
Predictors of response to the head-up tilt test in patients with unexplained syncope or presyncope
In clinical assessment, patients were judged symptomatically if they had a history of symptoms of heart failure (NYHA class [greater than or equal to] II) and/or angina (Canadian Cardiovascular Society class [greater than or equal to] 1) and/or exertional presyncope
or syncope considered due to aortic stenosis and the information was recorded.
Palpitations may be associated with presyncope
, syncope, chest pain or abnormal pulsations in the neck.
Type 2 : la presyncope
pendant laquelle le patient a une sensation de perte de conscience imminente.
This suggests that the risk of falling in the elderly is related to several factors, such as cardiovascular impairment that may lead to presyncope
Objective: To determine the value of bedside heart-type fatty acid binding protein in diagnosis of cardiac syncope in patients presenting with syncope or presyncope
Syncope or presyncope
, which occurs in about one-third of patients, is thought to be related to dysrhythmia or decreased cardiac output (Centeno, 2011).
