In this study, we aimed at determining how many leads are necessary for accurately reconstructing ECG potentials during atrial fibrillation (AF) on the body surface. Although the standard ECG is appropriate for the detection of this arrhythmia, its accuracy for extracting other diagnostic features or constructing surface potential maps may not be optimal. We evaluated the suitability of the standard...
Electrical atrial activation during atrial fibrillation shows an uncoordinated pattern. Invasive studies and computer models have shown that functional and anatomical barriers can sustain atrial fibrillation. Mechanisms involved in the fibrillatory process are multiple wave reentry, rotors and spiral waves. We have developed a new diagnostic tool with the aim to characterize electrical activation...
