Abstract

A method for optimizing electronic signal monitoring study performance includes assessing study criteria to determine an appropriate noise reduction circuit and selecting an appropriate noise reduction circuit from a plurality of noise reduction circuits in an electronic signal monitoring system. The study is then conducted using the selected noise reduction circuit.

Claims

1. A method for optimizing performance of an electronic signal monitoring study comprising:

assessing study criteria to determine an appropriate noise reduction circuit;

selecting via a computer-implemented user interface an appropriate noise reduction circuit from a plurality of noise reduction circuits in an electronic signal monitoring system, wherein at least one of the plurality of noise reduction circuits is a right leg drive circuit;

connecting ECG cables from the electronic signal monitoring system to a patient;

and

obtaining a noise reduced ECG trace through operation of the electronic signal monitoring system using the noise reduction circuit.

2. A method for optimizing performance of an electronic signal monitoring study comprising:

assessing study criteria to determine a right leg drive circuit;

selecting via a computer-interface an appropriate right leg drive circuit from a plurality of right leg drive circuits operatively connected to an electrocardiography amplifier;

connecting ECG cables from the electrocardiography amplifier to a patient; and

obtaining a noise reduced ECG trace through operation of the electrocardiography amplifier using the selected right leg drive circuit.

3. The method of claim 2 further comprising:

modifying the selected right leg drive circuit to increase its performance.

4. The method of claim 2 further comprising:

receiving information regarding the choice or performance of the selected right leg drive circuit.

5. The method of claim 4 further comprising:

selecting a new right leg drive circuit, or modifying the right leg drive circuit originally selected, based on the received information; and

conducting the study with the new or modified right leg drive circuit.

6. The method of claim 2 wherein the right leg drive circuits include at least one active right leg drive circuit.

7. The method of claim 2 wherein the right leg drive circuits include at least one passive right leg drive circuit.

8. A system for optimizing electrocardiography study performance comprising:

an amplifier;

a controller operatively connected to the amplifier;

A plurality of noise reduced circuits operatively connected to the controller and amplifier, wherein at least one of the plurality of noise reduction circuits is a right leg drive circuit; and

ECG cables operatively connected to the amplifier for connection to a patient;

wherein the controller may be used to select or modify one of the noise reduction circuits given study criteria.

9. The system of claim 8 wherein the plurality of noise reduction circuits are operatively connected to the controller via a switching circuit.

10. The system of claim 8, further comprising a user interface operatively connected to the controller.

11. The system of claim 10 wherein the controller provides study performance data to a user via the user interface so that a user can assess whether a new noise reduction circuit should selected or whether the selected circuit should be modified.

12. The system of claim 8 wherein the noise reduction circuits are right leg drive circuits.

13. The system of claim 12 wherein the right leg drive circuits include at least one active right leg drive circuit.

14. The system of claim 8 wherein the controller includes a processor and memory storage containing a program of instructions allowing a user of the system to select a noise reduction circuit that is appropriate given study criteria.
