Abstract

A pre-conditioned ECG system and method includes a patient signaling device configured to alert the patient to minimize the patient'"'"'s activity so that an ECG measurement may be taken, and further alerts the patient when the measurement is completed. The pre-conditioned ECG system and method also includes a pre-set buffer configured to hold a preset length of ECG data, and further configured to hold pre-set ECG parameters such as mean R-R interval, standard deviation of R-R interval, or simple rhythm analysis. The system and method may analyze the current 10 seconds of ECG data when the preset parameters are met or when selected parameters are met.

Claims

1. An ECG acquisition device for collecting ECG data from a patient, the ECG acquisition device comprising:

a set of ECG leads configured to connect to a patient and to collect a set of ECG data from the patient;

a communication port configured to receive a set of instructional data, wherein the instructional data includes a set of start and stop times; and

a patient signaling mechanism configured to signal the patient when a start time occurs and when a stop time occurs,

wherein the set of ECG data is collected from the patient between the start time and the stop time.

2. The device as claimed in claim 1, wherein the patient signaling mechanism includes any of the following:

a light;

an audible signal mechanism, wherein the audible signal mechanism is configured to produce any of an audible alarm or audible instructions; and

a vibrating mechanism.

3. The device as claimed in claim 1, wherein the communications port is further configured with a signal output, wherein the signal output includes an audio signal corresponding to the start time and the stop time.

4. The device as claimed in claim 3, wherein either one of the communication port receiving the set of instructional data and sending the signal output is effectuated through a wired connection.

5. The device as claimed in claim 3, wherein either one of the communication port receiving the set of instructional data and sending the signal output is effectuated through a wireless connection.

6. The device as claimed in claim 1, wherein the set of ECG leads include at least one ECG lead.

7. The device as claimed in claim 1, wherein the set of ECG leads includes a standard lead set.

8. The device as claimed in claim 1, wherein the ECG acquisition device is a Hotter monitor.

9. The device as claimed in claim 1, further comprising a data storage medium and a processor, the data storage medium configured to store the set of instructional data, and the processor configured to read and execute the set of instructional data.

10. A method of collecting a set of ECG data from a patient, the method comprising:

connecting an acquisition device to the patient with a set of ECG leads;

loading the acquisition device with a set of instructional data, wherein the set of instructional data includes a set of start times and stop times;

alerting the patient when a start time arrives, wherein the start time signals that the set of ECG data is being recorded with the ECG leads; and

alerting the patient when a stop time arrives, wherein the stop time signals that the recording of the ECG data has ended.

11. The device as claimed in claim 10, wherein the alerting step is effectuated by any of the following:

a light;

an audible signal mechanism, wherein the audible signal mechanism is configured to produce any of an audible alarm or audible instructions; and

a vibrating mechanism.

12. The method as claimed in claim 10, wherein the loading step is effectuated by a communications port, wherein the communications port is further configured with a signal output, wherein the signal output includes an audio signal corresponding to the start time and the stop time.

13. The method as claimed in claim 12, wherein either one of the loading step or the signal output is effectuated through a wired connection.

14. The method as claimed in claim 12, wherein either one of the loading step or the signal output is effectuated through a wireless connection.

15. The method as claimed in claim 10, wherein the set of ECG leads include at least one ECG lead.

16. The method as claimed in claim 10, wherein the set of ECG leads includes a standard lead set.

17. The method as claimed in claim 10, wherein the ECG acquisition device is a hotter monitor.

18. A method of preconditioning an ECG system for collection of ECG data from a patient, the method comprising:

connecting an acquisition device to the patient with a set of ECG leads;

loading the acquisition device with a set of pre-conditions;

collecting and storing a prior segment of ECG data and a current segment of ECG data when the prior segment of ECG data satisfies the set of preconditions.

20. The method as claimed in claim 18, wherein a duration of the prior segment of ECG data and the current segment of ECG data is adjustable by a user.

21. The method as claimed in claim 18, further comprising conducting the pre-determined ECG analysis of the prior segment of ECG data.

19. The method as claimed in 18, wherein the set of pre-conditions includes any of the following parameters:

mean R-R interval;

standard deviation of R-R interval;

variation of repolarization, wherein the variation of repolarization is a function of QT variation and T wave morphology variation; and

simple rhythm analysis.

22. A pre-condition ECG system, the system comprising:

a set of ECG leads configured to collect a prior segment of ECG data and a current segment of ECG data from a patient;

a database for storing the prior and current segments of ECG data;

a storage medium for storing a computer application and a set of pre-conditions; and

a processing unit coupled to the set of ECG leads and the storage medium, and configured to execute the computer application,

wherein when the computer application is executed, the current segment of ECG data is analyzed when the set of pre-conditions is satisfied, and further wherein a set of results are stored in the database.
