 In a few devices

, the operator can pick out the lead groupings, their sequence, and the recording duration for every institution. In popular 12-lead tracings, signals from each organization of leads (i.E., bipolar, augmented, precordial) can be recorded for 2.5 seconds. For a rhythm strip, one lead (normally lead II) is recorded for a full 12 seconds. Reported problems Because electrocardiographs have electric safety requirements which are properly hooked up and adhered to via all main manufacturers, few problems are related to their use. Of those, the most commonplace is artifact or noise (e.G., broken electrode wires, terrible electrode cleansing or fallacious utility, terrible skin training, affected person motion, baseline drift, and interference). Incorrect placement of ECG leads can purpose an abnormality to be unnoticed. Chest wall thickness also can affect diagnostic accuracy.
