1 doctor agrees

In brief: See below

Sinus tachy with artifact is a normal but fast rhythm (>100) with externally caused variations in the appearance of the tracing caused by body movement, poor electrode contact or external electrical interference.
Sin. tachycardia with PVC is normal but fast rhythm (rhythm >100), & a premature ventricular contraction (PVC), which is an abnormal early heart beat originating in one of the ventricles.
