Figure 3: 1:2 Non-reentrant Dual Atrioventricular Nodal Tachycardia and Tachycardia-induced Cardiomyopathy.

Figure 3:

A 59-year-old woman with hypertension but no other past medical history presented with new onset heart failure symptoms. An echocardiogram revealed a left ventricular ejection fraction (LVEF) of 20 % with normal left ventricular (LV) wall thickness and a dilated LV cavity. Electrocardiogram revealed 1:2 non-reentrant dual atrioventricular nodal tachycardia, which was successfully ablated. Repeat echocardiogram performed two months later revealed normalisation of her LV cavity size and systolic function.
