Abstract
An apparatus for body surface mapping comprises a plurality of electrodes for attachment to spatially separate locations on a human torso with each electrode capable of detecting the electrical activity associated with a heartbeat and producing a corresponding voltage. The electrodes are sampled at a rate of 1 KHz during a cardiac cycle and sets of sampled values are produced and stored. Positional variations of the maximum and minimum sampled values over time are displayed as a projection of trajectories of the maximum and minimum sampled values in a three dimensional (x, y, t) space onto planes perpendicular to a plane containing the electrodes.
