Item Refractory adenosine-sensitive congenital His bundle tachycardia: response to calcium-channel blockers.(2003-05-17) Sharada, K; Narasimhan, C; Rao, K Nageshwar; Soma Raju, BThe congenital form of His bundle tachycardia is an uncommon pediatric arrhythmia. We report the case of a 7-year-old child with tachycardiomyopathy. The incessant arrhythmia, detected in infancy, was resistant to amiodarone and beta-blockers. During electrophysiologic study, the tachycardia converted to sinus rhythm with intravenous adenosine and diltiazem. Subsequently, the child is maintaining sinus rhythm on oral verapamil. Calcium-channel blockers should be considered for the treatment of this arrhythmia, which is often resistant to multiple antiarrhythmic drugs.
