(a) Echo showed RV diameter 31.8 mm, the wall of the RV became thinner. (b) CMRI showed foci of fat in right ventricular free wall.

Echo showed the right ventricular (RV) was significantly dilated (RV diameter 31.8 mm), RVED/LVED = 0.67, the wall of the RV became thinner, interwoven reticular muscle fiber structure can be seen in the RV (Figure 1). Cardiac magnetic resonance imaging (CMRI-in local hospital) revealed a dilated right ventricular outflow tract, thin right ventricular wall with reduced wall motion, and foci of fatty deposit in the right ventricular free wall (Figure 1).
(a) ECG showed epsilon wave, paired PVC, QRS = 118 ms. (b) The third day after oral propafenone 200 mg, q8h, ECG showed QRS =170 ms, with dizziness. (c) The second day after half oral propafenone 100 mg, q8h, ECG showed QRS = 120 ms. (d) After 6 month oral sotalol 80 mg, q12h, ECG showed QRS = 124 ms.

ECG showed epsilon wave and paired PVC (Figure 2a). QRS was nearly normal, 118 ms (Figure 2a). QRS duration in this article is measured with V5 andII leads. On third day of oral propafenone, QRS was increased to 170 ms (Figure 2b). We reduced the dose of propafenone by half, and on next day, QRS was reduced to 120 ms (Figure 2c). At 6 months of illness, QRS returned to normal:ECG showed QRS was 124 ms (Figure 2d).
