<p>Apparatus is disclosed for monitoring cardiac contractility. A catheter has a tip (1) for insertion into the ventricle of the heart muscle. At or proximate the tip is an acceleration transducer (2) responsive to the natural heart acceleration to provide an acceleration signal via said catheter to signal processing means (9). The signal processing means and/or the acceleration transducer is or are arranged to suppress frequencies outside the range approximately 15 Hz to approximately 100 Hz.</p> |
