Cardiokymograph

Noninvasive device, placed on the chest, capable of recording anterior left ventricle segmental wall motion; consists of a 5-cm diameter capacitive plate transducer as part of a high frequency, low-power oscillator with recording probe; changes in wall motion affect the magnetic field and thus the oscillatory frequency which is then recorded on a multichannel analog waveform polygraph.
