Abstract:
An apparatus for acquiring and analyzing data relating to a physiological condition of a subject, the apparatus including: a sensor device for coupling to the subject, the sensor device for detecting, converting and transmitting digital signals corresponding to four analog signals, one of the four analog signals being an electrocardiograph signal and three of the four analog signals being ballistocardiograph signals, and a computer including a processor in communication with the sensor device, the computer for receiving the digital signals from the sensor device and analyzing the digital signals, the computer generating and outputting a report relating to the physiological condition of the subject.
Abstract:
A method for locating and marking points on a waveform includes: providing electrocardiogram and ballistocardiogram waveform data correlated in time and extending for at least two heart beats, one of the at least two heart beats being an annotated heart beat having cardiac events identified thereon, the cardiac events including a reference event marked on an electrocardiogram waveform, generating a template based on the annotated heart beat, the template including time intervals measured from the reference event to other cardiac events; and locating the reference event on each non-annotated heart beat and applying the template to determine locations of the other cardiac events.
Abstract:
A method for locating and marking points on a waveform includes providing data corresponding to electrocardiogram and ballistocardiogram waveforms correlated in time, searching the data to locate points corresponding to cardiac events, a location of each of the points corresponding to cardiac events being defined by a rule set, identifying and storing the points corresponding to cardiac events and outputting a visual representation including the points corresponding to cardiac events marked on the electrocardiogram and ballistocardiogram waveforms.
