Wide QRS waves with no preceding P waves and atrioventricular dissociation strongly suggested that the arrhythmia was VT. Green triangle: The start of wide QRS waves lacked the preceding P wave. The sinus P waves thought to be hidden by wide QRS waves are shown by the green arrow as well. Black arrow: Sinus P waves. The fourth P wave (orange arrow) was not judged to be connected with the following wide QRS wave, suggesting atrioventricular dissociation. The fourth P wave (blue arrow) was not judged to be connected with the following wide QRS wave, because of its shorter PQ duration than usual. Atrioventricular dissociation was suspected
