Monitoring Physiological Condition and Detecting Abnormalities
First Claim
1. A method for determining one or more parameters characteristic of an individual'"'"'s cardiac function, said method comprising:
- acquiring electrocardiograph and ballistocardiograph signals from said individual;
converting said electrocardiograph and ballistocardiograph signals into electrocardiograph data and ballistocardiograph data;
receiving said electrocardiograph data and ballistocardiograph data at a computer, said computer including a microprocessor;
synchronizing, by said microprocessor, said electrocardiograph data with said ballistocardiograph data to provide at least one synchronized electrocardiograph-ballistocardiograph waveform;
identifying, by said microprocessor, one or more components of said synchronized electrocardiograph-ballistocardiograph waveform, said components indicative of said one or more parameters characteristic of an individual'"'"'s cardiac function.

Abstract
A system for monitoring an individual'"'"'s physiological condition and detecting abnormalities therein, comprising concurrently receiving at least a first signal and a second signal. The first and second signals are conditioned to minimize background extraneous noise after which, each signal is concurrently processed and analyzed to detect repeating cyclical patterns and further characterized to identify individual components of the repeating cycles. At least one individual component in one signal is selected as a reference marker for a selected component in the other signal. The two signals are then synchronized, outputs produced therefrom and stored in a database. The system is provided with a plurality of devices for acquiring, transmitting and conditioning at least two physiological signals, a software program cooperable with a microprocessor configured for receiving said transmitted signals and conditioned signals, and processing said signals to characterize and synchronize said signals and provide signal outputs derived therefrom, a database for storing said transmitted signals, conditioned signals, synchronized signals, and output signals derived therefrom. The output signals are useful for reporting and optionally for retransmission to the individual'"'"'s body and providing physiologically stimulatory signals thereto.
