Abstract
A handheld electrocardiogram monitor with electrodes mounted on swing arms which are rotatably mounted on the bottom case of the ECG monitor housing, to which the swing arms are frictionally engaged and also engaged by means of a detent mechanism which includes a combination of detent grooves and ball spring plungers. The grooves are provided with 60.degree. spacing on standoffs mounted on the swing arm, and the ball plungers are mounted on the bottom case of the monitor in positions 90.degree. apart about the rotational axis. The 60.degree. phasing of the grooves combines with the 90.degree. spacing of the plungers to provide 30.degree. indexing.
