Table 2 Classification of electrocardiographic artifacts with examples

Category	Source	ECG appearance	Clinical mimic	Solution
Patient-related	Tremor, shivering, respiration, movement	Irregular baseline, wandering drift	AF, flutter, VT, ST changes	Patient cooperation
Equipment-related	Loose electrodes, fractured cables, faulty machine	Baseline jumps, flatline, spikes	Asystole, VF	Change cables, better skin preparation, electrode contact
Environmental	Power-line hum, cautery, ventilators	Saw-tooth oscillations, rhythmic noise	Flutter, VT	Avoidance of equipment, notch filters
Device-related	Pacemaker, LVAD, neurostimulators, IVL	Sharp spikes, continuous noise	VF, tachycardia	Not always possible

ECG: Electrocardiogram; AF: Atrial fibrillation; VT: Ventricular tachycardia; VF: Ventricular fibrillation; LVAD: Left ventricular assist device; IVL: Intravascular lithotripsy.
