cardiokymograph

car·di·o·ky·mo·graph

(kar'dē-ō-kī'mō-graf),

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.
