A 19-year-old male presented with dyspnea on exertion (New York Heart Association [NYHA] class II) and occasional palpitations for six months. He had initially been evaluated at another facility and diagnosed with dilated cardiomyopathy. Despite treatment, there was no improvement in his symptoms. On evaluation at our centre, his previous electrocardiograms appeared normal. However, palpation of his radial pulse for one minute revealed runs of regular tachycardia, interspersed with a normal pulse rate. A 30-second rhythm strip electrocardiogram (ECG) showed multiple runs of ectopic tachycardia originating from the right atrial appendage, interspersed with ectopic atrial rhythms. Echocardiography showed severe left ventricle (LV) dysfunction with an ejection fraction of 20-25%. Radio-frequency ablation was recommended, but the patient declined. Instead, he was started on Ivabradine. After a month, his symptoms fully resolved. The ECG displayed a normal sinus rhythm with no tachycardia, and his left ventricular ejection function improved.
