About this trial
Cardiac electrical activity is detected on the body surface with conventional electrocardiography involving 12 leads (ECG 12). A limitation of the current ECG technique is that recordings are obtained from only 6 independent precordial leads pairs ; which may miss cardiac potentials from spatially limited regions. More extensive sampling of the body surface may contribute to additional clinical information. The present study investigates the additional sensitivity of ECG using 128 body surface leads (High Density (HD) ECG) in measuring global or regional cardiac activity.
