Mechanisms of Cough Syncope as Evaluated by Valsalva Maneuver

Mechanisms of cough syncope as evaluated by valsalva maneuver.

Successful treatment of cough syncope depends on the correction of various pathogenetic mechanisms among different patients. The valsalva maneuver (VM), which elicits hemodynamic responses mimicking coughs, has potential for investigating the individual pathogenesis of cough syncope. Eighteen consecutive patients suffering from cough-induced syncope were examined. All patients were asked to cou...

Cerebral syncope: insights from Valsalva maneuver.

BACKGROUND AND PURPOSE Cerebral syncope refers to a loss of consciousness associated with cerebral vasoconstriction in the absence of systemic hypotension. The diagnosis of cerebral syncope could be established by the head-up tilt test (HUT) and transcranial Doppler ultrasonography. Valsalva maneuver (VM) permitted assessment of cerebral autoregulatory function by provoking blood pressure (BP) ...

Cough syncope misinterpreted as epileptic seizure.

Cough syncopes are rare but may be one of the cause of sudden loss of consciousness. We recorded under video-EEG monitoring a typical syncope triggered by voluntary coughing (video) and Valsava maneuvre in a patient referred for the diagnosis of generalized tonic-clonic seizures. There were no signs of active epilepsy. The attacks were associated with overweight, obstructive sleep apnea and hea...
