Accelerated ventricular rhythm
Accelerated ventricular rhythm due to enhanced automaticity of a ventricular pacemaker, presents as a regular wide QRS rhythm. AV dissociation is common and capture and fusion beats, to be discussed later, are also common. Rates ranging from 50-120 beats per minute are typical. The term “slow” ventricular tachycardia is sometimes used to differentiate these slower rhythms due to enhanced automaticity of a ventricular pacemaker from more rapid and more ominous ventricular tachycardias due to reentry. Accelerated ventricular rhythm is common post myocardial infarction with or without reperfusion therapy. The following animation illustrates what we have just described.
