Cardiac syncope Cardiac syncope is the most dangerous cause of syncope and is the reason for most syncope admissions. 3,14 Fortunately, most of these can be identified by risk stratifying patients in the ED with a thorough history, physical examination, and an electrocardiogram (ECG). The basic mechanism underlying cardiac syncope is the inadequacy of cardiac output to maintain cerebral perfusion. Often, an underlying structural abnormality or preexisting heart condition is the primary cause or contributing cause of cardiac syncope.
62 Many of the toxic effects result from the sodium channel blocking and anticholinergic effects. 63 Telemetry monitoring should be continued until the serum carbamazepine levels have returned to the therapeutic range,64 with the understanding that absorption of the drug is often delayed and erratic. Electrocardiogram, complete metabolic profile, and a CBC should be ordered to evaluate for the hyponatremia and cardiac conduction effects that are seen in acute toxicity, and for the hepatic toxicity and blood dyscrasias that can occur with chronic use of the medication.
Patients who present with symptoms of near syncope should be treated as if they had syncope. Near syncope and true syncope are on a spectrum, with similar underlying causes resulting in decreased blood flow to the brain. Associated injury during a syncopal event Contrary to common belief, injuries suffered from syncope do not help in determining whether the inciting mechanism is dangerous or benign. It is often thought that those without prodrome are more likely to be cardiac and would therefore be more likely to have associated injuries.
