ECG Artifacts Simulating Atrial Flutter
Abstract
To the Editor.—
Atrial flutter (223: 439, 1973), or ventricular fibrillation as reported by Labram (Nouvelle Presse Med 1:2402, 1972) and by Delzant (Nouvelle Presse Med 2:112, 1973) may be simulated by muscular tremulation with typical parkinsonism. A simple method of avoiding such artifacts is to place the two brachial electrodes (or even one if the tremulation is exactly unilateral) on the deltoid areas and not on the arms or forearms. The Figure emphasizes this fact, often...
