Carotid sinus massage as a diagnostic and therapeutic tool for atrial flutter-fibrillation.
Alterations in vagal tone can influence the atrial fibrillatory process by changing the atrial refractory period. We observed in a patient with paroxysmal atrial fibrillation (AF) that carotid sinus massage (CSM) changed a "coarse" type of fibrillation into a "fine" type, followed by termination of the arrhythmia. Although coincidental conversion of AF into sinus rhythm could not be excluded, we concluded that it is worth while to try CSM in every patient presenting with AF prior to other interventions to restore sinus rhythm.
