NOVELTY - A system has a software program with at least one algorithm to process and synchronize conditioned first and second signals, and deriving output from synchronized signals; a microprocessor that receives conditioned first and second signals from a third device; and a database that stores signals transmitted from first, second and third devices and outputs generated by microprocessor. Microprocessor cooperates with software program to process and synchronize conditioned first and second signals and generate output derived from synchronized signals indicating individual's physiological condition.    USE - System for monitoring and detecting abnormalities in physiological condition such as cardiovascular abnormalities and malfunctions of individual by concurrently detecting and processing electrocardiograph (ECG) and ballistocardiography (BCG) signals for use as routine testing method in clinical environment such as medical doctor's office, walk-in clinic, clinical laboratory, testing facility associated with medical research institute, testing facility associated with hospital. Can also be optionally adapted for employment in exercise and training facilities for observing, recording and storing changes in individual's cardiovascular system during periods of exercise and training for purposes of monitoring improvements in cardiovascular fitness and for detection of onset of potential cardiovascular malfunctions.    ADVANTAGE - Enables and facilitates detection of potential abnormalities and malfunctions associated with the individual's cardiovascular system by synchronization of selected signal to other signal. Enables synchronization of individual's rhythmic BCG pattern with the ECG signal under non-stressed i.e. resting stage conditions and characterize the individual's cardiac function by calculating e.g. stroke volume, cardiac output, ending diastolic volume, ending systolic volume regardless of the type of BCG wave pattern produced by individual under stressed conditions in reference to Starr classification system.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for monitoring and detecting abnormalities in an individual's physiological condition.    DESCRIPTION OF DRAWING(S) - The drawing shows a graph of the comparisons of overlaid synchronized pre- and post-exercise BCG signals for the healthy individual, unhealthy individual, and at-risk individual respectively.
