| Popis: | A 65-year-old man experienced syncope associated with advanced atrioventricular (AV) block upon swallowing. Continuous electrocardiogram (ECG) monitoring revealed first and second degree AV block. ECG revealed advanced AV block (Max R-R 6.38 s) upon swallowing, a cold drink. Demand ventricular pacing alleviated his symptoms. In this patient, the advanced AV block might have been precipitated by a vagovagal reflex triggered by expansion of the esophagus, resulting in selective suppression of the atrioventricular node. |
