Electrocardiograms typically measure electrical activity across the heart. Occasionally additional electrical activity can show up on an ECGElectrocardiogram; also called an EKG; a representation of electrical voltage measured across the chest over a period of time. 1. Six Second ECG Guidebook (2012), T Barill, p. 196. This includes electrical activity of other muscles (movement artifact). ie. brushing with a non-electric toothbrush can produce a rhythmic rapid series of additional electrical waveforms. Other types of artifact can be caused by breathing (increasing distances between the electrodes – respiratory artifact) and by non-grounded electrical devices (60hz artifact of AC current).
ECG Sim RhythmOften refers to a discernible pattern in time or distance between QRS complexes and/or P waves. Deck
