Abstract
An adjustable template device for pacemaker ECG analysis is similar to a slide rule with a transparent window portion which can be laid over an ECG trace to aid in its analysis. A frame for the template has a back member and a cover member connected together with rivets, with the cover member having cutout portions through which various scales printed on the back portion can be seen. A series of movable transparent plastic sheets slide back and forth independently in the frame to allow measurement of time intervals on the ECG trace. Fiducial marks on the movable sheets indicate time intervals by their positions with respect to scales on the back member. AV, AE, MT, PVAR, and pacing intervals can all be set simultaneously on the template. A photocopy of the template overlying the ECG trace can be made to provide a permanent record.
