Key result
Metoprolol tartrate tablets were effective in treating swallowing-induced atrial tachycardia related to a neural reflex in a 53-year-old man.
Case Report (n=1)
Swallowing-induced atrial tachycardia may be related to a neural reflex involving sympathetic nerves, and can be effectively treated with metoprolol.
May support beta-blocker trial in swallowing-induced atrial tachycardia; leaves open prospective validation.
A 53-year-old man presented with heart palpitations while swallowing. Electrophysiologic study (EPS) and immunohistochemical results of his esophageal leiomyoma suggested that swallowing-induced atrial tachycardia is related with neural reflex. S100-immunopositive nerve fibers are demonstrated sympathetic nerves which possibly explain the mechanism. Metoprolol tartrate tablets are effective in our patient.
