Figure 1. Monomorphic ventricular tachycardia (VT, VTach). P-waves are visible but they do not have any relation to the QRS complexes. This situation is referred to as “AV dissociation” and indicates that atrial and ventricular activity and independent. AV dissociation confirms that the arrhythmia is ventricular tachycardia. However, AV dissociation is frequently difficult to spot.
