Abstract
Abstract An electrocardiogram (EKG) data strip is constructed with contiguous, repetitive segments to allow individual heart lead tracings recorded on the segments to be readily removed from the EKG data strip after the tracings have been completed so that the segments can then be inserted directly into a permanent record form. The EKG data strip of the present invention has a first longitudinal line of perforations along one edge, a second longitudinal line of perforations adjacent the other edge and a plurality of transverse lines of perforations extending across the EKG data strip between the first and second longitudinal lines of perforations. The transverse lines of perforations are located at spaced intervals along the length of the EKG strip to thereby divide the central part of the strip into a plurality of longitudinally aligned segments, each of which has a predetermined width between the longitudinal perforations and a predetermined length between two adjacent transverse perforations. Each segment is readily detachable from the EKG data strip along the longitudinal and transverse perforations. The segments can be detached as individual, single segments, or two or more contiguous segments can be detached to provide a rhythm strip in which adjacent segments are connected together by undetached transverse perforation lines between the adjacent segments.
