Abstract
In an electrocardiographic system there is a multielement electrode at each skin location for providing an ECG signal of negligible magnitude between elements because of the close spacing while the pair of elements are sufficiently separated so that the motion of one element is at least partially independent of the motion of the other; thus, events causing a baseline shift will also cause a difference in potential between the two elements of a multielement electrode. That difference is detected by logical circuitry to produce a signal indicating baseline shift.
