PVCs (from 6 to 20 thousand per 24 hours registration), often arranged into ventricular bigeminy and trigeminy episodes (Figure 1). PVCs were then evenly distributed during registration, with one morphology.

The ECG performed during the consultation showed a sinus rhythm of 75 bpm and PVCs with a morphology pointing to the right ventricle outflow tract (RVOT) origin (Figure 2), which could indicate a potential possibility of radiofrequency ablation (RF) using with a positive effect.
Magnetic resonance of the heart. Panel (A) End-systolic (left) and end-diastolic (right) still frame of the 3-ch cine steady state free precession series showing normal chamber size and no significant abnormalities of the valves. Panel (B) End-systolic (left) and end-diastolic (right) still frame of the 4-ch cine steady state free precession series normal chamber size and no significant abnormalities of the valves. Panel (C) Single shot steady state free precession coronal image showing both LVOT and ascending aorta.

Additionally, cardiac magnetic resonance imaging was performed, excluding mitral valve prolapse and mitral annulus disjunction (Figure 3).
