ABSTRACT:
Ventricular arrhythmias are monitored and classified based upon various criteria. One criterion is PR dissociation which is determined by comparing the PR interval in a current RR cycle to a median PR value. If the current PR interval varies too far from the median, then dissociation is indicated. Often, there are multiple atrial events in a given RR interval and the PR value has been based upon the last atrial event in the cycle. An algorithm determines whether to use the last atrial event in a cycle or whether an earlier atrial event occurred and would provide a more accurate PR value.
