ABSTRACT
The article discusses the many potential artifacts and pitfalls which can adversely affect the interpretation of 12-lead ambulatory electrocardiograms (ECG). Artifacts can simulate arrhythmias such as atrial flutter and ventricular tachycardia and lead to inappropriate treatment. Other ECG changes that may be interpreted as ischemic in origin and can mimic serious arrhythmias are electrode and lead misplacements.

    T-wave alternans (TWA) are beat-to-beat amplitude oscillations in the T-waves of electrocardiograms (ECGs). Numerous clinical studies have demonstrated the link between these oscillations and ventricular arrhythmias. Several methods have been developed in recent years to detect and quantify this...

    Electrocardiograms (ECGs) are widely used by clinicians to identify the functional status of the heart. Thus, there is considerable interest in automated systems for real-time monitoring of arrhythmia. However, intra- and inter-patient variability as well as the computational limits of real-time...
