An elderly dialysis patient presented with chest pain. Regular means it can't be atrial fibrillation --Most regular wide complex tachcardia are VT, especially if the patient has poor LV function, as in this case. She has poor LV function. Severely decreased LV function. Here is her ECG: Regular Wide Complex Tachycardia.

In that sense, the term dysrhythmia is preferable because it does literally translate as a disturbance in normal rhythm which is exactly what it is meant to describe. Any unsolicited disturbance of the rate or rhythm can be termed a dysrhythmia and result in the heart beating less efficiently but only for the duration of the dysrhythmia.

Inferior MI results in scar tissue which is a likely source of a re-entrant ventricular dysrhythmia. Knowing the rhythm is precisely regular rules out any possibility of atrial fibrillation — and facilitates calculation of heart rate. This would be the likely source of the VT.
