Abstract
An instrument for recording the displacement of the cardiac apex relative to the rib cage has been constructed using a commercially available displacement transducer and operational amplifier. A simple E.C.G. unit for timing purposes is also described. Recordings using this instrument are comparable with the apexcardiogram obtained from a more expensive apparatus.Keywords
