Highlights
There are clearly visible sinus P-waves in the first two beats and in the last one
On an accurate analysis the second beat has shorter PR interval and a different QRS morphology compared to the previous one
There are two different pacemakers, one sinus and one ventricular, that coexist and compete each others to depolarize ventricles: as sinus rhythm slows down, ventricular pacemaker appears, until sinus pacemaker increases its rate again. This is an accelerated idioventricular rhythm, an arrhythmia due to an enhanced and unprotected ectopic ventricular pacemaker [1] with a rate between 50 and 120 beats per minutes, faster than normal intrinsic ventricular escape rhythm, but slower than ventricular tachycardia, that is influenced by sinus pacemaker, unlike parasystole
