Figure 1. Electrocardiograms from the proband.

Figure 1

(A) Representative lead II recording obtained at age 3 days illustrating wandering atrial rhythm with frequent multifocal premature ventricular beats. (B) Representative lead II recording obtained at age 7 weeks illustrating an episode of supraventricular tachycardia with variable 2:1 and 3:1 AV block. (C) Representative lead II recording obtained at age 6.5 months two weeks off amiodarone illustrating sinus rhythm with a prolonged QTc (480 ms). (D) Representative lead II recording obtained at age 9 months while the proband was off antiarrhythmic drugs illustrating multifocal ventricular ectopy and two 3–4 beat runs of nonsustained ventricular tachycardia. (E) Representative lead II recording obtained at age 20 months while treated with amiodarone and propranolol illustrating sinus rhythm. More complete ECG recordings corresponding to each of these events are provided as Supplemental Fig. S2.
