Abstract:
We describe the cases of two patients who exhibited a supraventricular tachycardia induced by swallowing. In both cases we found a systemic hypertension, other cardiac or gastroesophagic abnormalities were absent. The electrophysiologic studies demonstrated in the first case a supraventricular tachycardia with 1 : 1 AV-conduction and an origin in the right atrium, in the second case an atrial tachycardia with AV-block originating in the right atrium too. The pathogenetic mechanism is discussed. In both cases after treatment with amiodarone a complete cessation of the tachycardias was reached.
