Figure 4: Left brachiocephalic vein-aorta Doppler demonstrating the beginning of the tachyarrhythmia triggered by an atrial ectopic (pink arrow) and termination of the tachyarrhythmia followed by an atrial ectopic (blue arrow) and bradycardia. It is a long ventriculoatrial tachyarrhythmia (atrioventricular interval 267 ms; ventriculoatrial interval 600 ms) with 1:1 atrioventricular conduction
