Social anxiety provoked by speech-induced atrial tachycardia

چکیده
Introduction Focal atrial tachycardia (AT) mechanisms include enhanced automaticity and triggered activity. Autonomically mediated focal atrial arrhythmias (AT or atrial fibrillation [AF]) are rare. Adrenergic stimulation such as exercise or stress can initiate focal atrial arrhythmias by enhancing automaticity, whereas vagal nerve arrhythmogenicity is associated with reentry and early afterdepolarizations due to shortening of the action potential duration. We report the case of a patient with AT that was initiated with speech and dissipated with silence. The patient also had atrioventricular reentrant tachycardia.

Increased vulnerability to stress following opiate exposures: behavioral and autonomic correlates.
The authors used rats to study the impact of a history of opiate exposures on behavioral and autonomic responses to restraint stress. Brief restraint (30 min) provoked tachycardia and a pressor response, anxiety (as indexed by social interaction), grooming, and reduced exploration. The pressor response was reduced at 1 day, but not 7 days, after last opiate exposure; tachycardia was unaffected ...
متن کاملAn electrophysiologic study of swallowing-induced tachycardia.
Electrophysiologic studies were performed on a 73-year-old man with swallowing-induced supraventricular tachycardia, in order to define the characteristics of this unique dysrhythmia in this patient. Swallowing reliably provoked an automatic atrial focus type of atrial tachycardia, which usually changed into an atrioventricular nodal reentrant tachycardia when a critical delay in atrioventricul...
متن کاملAutomatic tachycardia recognition.
A microcomputer algorithm for tachycardia identification, suitable for use in an implanted antitachycardia pacemaker, is described. The system employs an atrial and ventricular electrogram, detects a sustained fast rate in either chamber, and awakens the main program to perform detailed analysis of the tachycardia and its immediately preceding beats. The algorithm distinguishes atrial, ventricu...

متن کاملCardioversion and the digitalized patient
Transthoracic synchronized direct current discharge or cardioversion was introduced nearly 25 years ago to restore sinus rhythm in patients with diverse tachyarrhythmias (I). This simple, expeditious and nearly complication-freemethod has withstood the test of time. The likelihood of serious adverse reactions is related more to the underlying mechanism being treated than to the electrical disch...
