Methods and apparatus for monitoring the heart motion of a subject employ a probe which can be coupled to a portion of the anatomy of the subject. The probe may couple to the subject's aortic arch or thyroid cartilage, for example. The probe is biased into contact with the subject. The probe detect s movements caused by the heart motion. The apparatus may display acceleration s and displacements caused by the heart motion. Waveforms from multiple anatom ic sites may be acquired, normalized in time and amplitude, and combined to produce resultant waveforms. Combining the waveforms may involve addition or subtraction. |
