Abstract

A single acquisition diagnostic monitoring system for monitoring electrophysiology data and hemodynamic physiological data from a subject of interest. The system comprises a first module configured to receive the electrophysiology data via a plurality of first sensors coupled to the subject of interest. The system also comprises a second module configured to receive the hemodynamic physiological data via a plurality of second sensors coupled to the subject of interest. The system also comprises a base unit coupled to each module and configured to supply electrical power to each module, to receive the data from each module, and to synchronize the data from each module together. The system also comprises a processor coupled to the base unit and configured to receive the synchronized electrophysiology and hemodynamic physiological data from the base unit, combine the synchronized data into a single database, and transmit the synchronized processed data for further use.

Claims

1. A single acquisition diagnostic monitoring system for monitoring electrophysiology data and hemodynamic physiological data from a subject of interest, the system comprising:

a first module configured to receive the electrophysiology data via a plurality of first sensors coupled to the subject of interest;

a second module configured to receive the hemodynamic physiological data via a plurality of second sensors coupled to the subject of interest;

a base unit coupled to each module and configured to supply electrical power to each module, to receive the data from each module, and to synchronize the data from each module together; and

a processor coupled to the base unit and configured to receive the synchronized electrophysiology and hemodynamic physiological data from the base unit, combine the synchronized data into a single database, and transmit the synchronized processed data for further use.

2. The system of claim 1, including an analog-out circuit coupled to the base unit and the processor, with the circuit configured to apply a predetermined filter received from the processor to the processed data.

3. The system of claim 2, wherein the processor is configured to generate the predetermined filter from a group consisting of low pass, high pass, and a combination of low and high pass filters available to the processor.

4. The system of claim 1, including a clock in each of the modules, base unit and processor, with all the clocks synchronized with a communication protocol.

5. The system of claim 1, wherein the processor and base unit are coupled together by one of a hardwire cable and a wireless network.
