An Intracardiac Manometer: Its Evaluation and Application
The miniature intracardiac manometer supplied a method for recording artefact-free pressure tracings from the heart and great vessels of man and the intact animal. This instrument has been applied to the procedure of cardiac catheterization. It has also been used to demonstrate that if motion artefacts can be minimized, the central pulse can be recorded with reasonable accuracy by means of manometric systems with relatively poor dynamic response. Illustrations of pulse waves within the heart and great vessels of man and dogs and the effects of varying the dynamic response of the recording system are included.
