Hemodynamic assessment/adjustment

A method utilizing signal-processed ECG and heart-sound signal information for assessing a pacemaker patient's hemodynamic condition comprising

• collecting, over a selected time span, for transmission for hemodynamic-condition signal processing, simultaneous ECG-electrical and heart-sound acoustic signals,
• while so collecting, detecting, electrically, pacemaker-induced ventricular stimulation, and
• on detecting such stimulation, creating and applying a selected blanking time which effectively prevents hemodynamic-condition signal-processing of acoustic signals that are collected during that blanking time.

A system for assessing a patient's hemodynamic condition comprising

• sensor structure for collecting, over a selected time span, for hemodynamic-condition signal-processing, simultaneous ECG-electrical and heart-sound acoustic signals,
• signal-processing structure operatively connected to said sensor structure for receiving therefrom and processing such collected ECG-electrical and heart-sound acoustic signals, and
• display structure operatively connected to said signal-processing structure for producing, based on processing performed by said signal-processing structure, a comprehensive time-based display including (a) ECG and acoustic waveforms, and (b) geometric graphical indicia generally keyed to these waveforms, whereby the produced-display waveforms and graphical indicia collectively present a visual description of the patient's hemodynamic condition.
