Specialized syncope evaluation.
The concept of specialized cardiovascular care is not new. Nearly 4 decades ago, Killip and Kimball1 reported the results of their study of the treatment of 250 patients with myocardial infarction in a coronary care unit. With continuous ECG monitoring at a centralized nursing station, defibrillators at each bedside, and nurses authorized to deliver precordial shocks if physicians did not respo...

Syncope is an important clinical problem which accounts for 1% of hospital admissions and 3% of emergency department visits with a reported mortality and major morbidity rate of...
متن کاملEvaluation of syncope.
Syncope is a transient and abrupt loss of consciousness with complete return to preexisting neurologic function. It is classified as neurally mediated (i.e., carotid sinus hypersensitivity, situational, or vasovagal), cardiac, orthostatic, or neurogenic. Older adults are more likely to have orthostatic, carotid sinus hypersensitivity, or cardiac syncope, whereas younger adults are more likely t...
متن کاملClinical evaluation of syncope.
Reduction of blood flow to both cerebral hemispheres or the brainstem (reticular activating system), results in acute hypoperfusion. This leads to loss of consciousness and postural tone, with resulting syncope. As syncope is a transient event, it follows that the cause of central nervous system (CNS) dysfunction must also be transient. Persistent causes of significant CNS dysfunction results i...
