Electrical Alternans by ECG Finding

Computational models of human atrial cells, tissues and atria have been developed. Cell models, for atrial wall, crista… (More)

Electrical alternans is a pattern of variation in the shape of the ECG waveform that appears on an every-other-beat basis. In… (More)

Beat-to-beat alternations of the cardiac monophasic action potential, known as electrical alternans, were studied at drug… (More)

Electrical alternans are believed to be linked to the onset of life-threatening ventricular arrhythmias and sudden cardiac death… (More)

This investigation was performed to evaluate the feasibility of detecting repolarization alternans with the heart rate elevated… (More)

Electrical alternans at the repolarization phase of the cardiac cycle have been reported to be related with increased risk for… (More)

BACKGROUND Although electrical alternans (alternating amplitude from beat to beat on the electrocardiogram) has been associated… (More)

This paper reports the results of a theoretical investigation of spiral wave breakup in model equations of action potential… (More)

Electrical and mechanical alternans have often been found to coexist. However, the factors controlling their interdependence are… (More)
