An Application of Opte-electronics to Bio-signal Processing

Abstract

In clinical electrocardiography, the 10 basic electrode-body connections viz., left arm (LA), right arm (RA) left leg (LL), V₁, V₂, V₃, V₄, V₅, and V₆ are combined in different configurations to form the 12 ECG leads, nominated as lead I, lead II, lead III, a V_R, a V_t, a V_F, V₁, V₂,.….V₆ the outputs from which are recorded sequentially for localising an ischemic process and evaluating the degree of damage caused by the same. It is now an increasingly common clinical practice to record the 12 leads in sets of 2 or more leads at a time, to enable the visualisation of the electrical changes taking place is these leads concurrently and not after a certain delay as is the case with the common i.e. serial method of recording ECG. This is the genesis of the multichannel or parallel recording of ECG leads, which offers the additional advantage of a three-fold saving in recording time.
