Abstract

Methods, devices and systems for obtaining heart rate by obtaining apical and non-apical heart rate datum using first and second heart rate monitoring devices. The apical and non-apical heart rate data are input into a heart rate verification module (HRVM) that includes a number of programming instructions for effecting the invention. An apical heart rate measure and non-apical heart rate measure are calculated in the HRVM, and an acceptable heart rate range is generated using the apical heart rate measure. Whether the non-apical heart rate measure is a reliable measure of a true heart rate is identified by determining whether the non-apical heart rate measure falls within or outside the acceptable heart rate range. A split display screen of the HRVM displays the apical heart rate measure, non-apical heart rate measure, and information identifying whether the non-apical heart rate measure falls within or outside the acceptable heart rate range.

Claims

1. A method of obtaining heart rate comprising:

connecting a patient to a first heart rate monitoring device;

obtaining non-apical heart rate data of the patient using the first heart rate monitoring device;

obtaining apical heart rate data of the patient by auscultation using a second heart rate monitoring device;

transmitting the non-apical heart rate data and the apical heart rate data to a processor performing heart rate verification;

calculating both a non-apical heart rate measure and an apical heart rate measure using the processor;

calculating an acceptable heart rate range using the apical heart rate measure;

determining whether the non-apical heart rate measure falls within the acceptable heart rate range;

outputting to a display an identification that identifies whether the non-apical heart rate measure falls within or outside the acceptable heart rate range, whereby when the non-apical heart rate measure falls within the acceptable heart rate range it is recognized as a reliable measure of a true heart rate and when the non-apical heart rate measure falls outside the acceptable heart rate range it is recognized as an unreliable measure of the true heart rate; and

outputting the identification to medical personnel for taking immediate action and providing the patient with medical attention if necessary,

wherein when the reliable measure of the true heart rate is obtained, validating that the non-apical heart rate remains to fall within the acceptable heart rate range such that it continues to be the reliable measure of the true heart rate.

2. The method of claim 1, wherein the apical heart rate is obtained using the second heart rate monitoring device in combination with a manually activated actuator component that outputs a signal corresponding to each time a user activates the manually activated actuator component when the user hears each auscultated apical heart rate data, each signal is output to the processor.

3. The method of claim 2, wherein the actuator component is attached to the second heart rate monitoring device.

4. The method of claim 2, wherein the actuator component is separate and distinct from the second heart rate monitoring device.

5. The method of claim 2, wherein the signal comprises a wireless signal.

6. The method of claim 1, wherein the first heart rate monitoring device comprises a pulse oximeter.

7. The method of claim 2, wherein the second heart rate monitoring device comprises a stethoscope.

8. The method of claim 1, wherein the processor resides within the second heart rate monitoring device.

9. The method of claim 1, wherein the processor resides within a component separate from the first and second heart rate monitoring devices.

10. The method of claim 1 further including outputting the calculated apical and non-apical heart rate measures to an end-user within about 3-10 seconds from obtaining the apical heart rate data.

11. The method of claim 1 wherein if the non-apical heart rate measure falls outside the acceptable heart rate range, then both the apical heart rate and the non-apical heart rate continue to be monitored until the non-apical heart rate measure falls within the acceptable heart rate range and is recognized as the reliable measure of the true heart rate.

12. The method of claim 1 further including ceasing obtaining the apical heart rate data when the non-apical heart rate measure falls within the acceptable heart rate range.

13. The method of claim 1 further including, when the non-apical heart rate falls outside of the acceptable heart rate range, continually monitoring both the apical heart rate and the non-apical heart rate until it is determined that the non-apical heart rate falls within the acceptable heart rate range and is recognized as the reliable measure of the true heart rate.

14. The method of claim 1 wherein if the non-apical heart rate measure is outside the acceptable heart rate range, then the non-apical heart rate measure is unreliable, and both the apical and non-apical heart rate measures are continued to be monitored and output.

15. The method of claim 1 wherein the apical heart rate data is manually obtained while the non-apical heart rate data is electronically obtained.

16. The method of claim 1 further including the processor having one or more unique indicators that visually, auditory, or both visual and auditory alert end-users of critical events that require action by the end-users.

17. The method of claim 1, wherein both the apical heart rate data and the non-apical heart rate data are continually refreshed to provide current apical and non-apical heart rate measures for output from the processor.

18. The method of claim 1 further including outputting the calculated apical and non-apical heart rate measures to one or more medical personnel, the one or more medical personnel making a determination based on the output apical and non-apical heart rate measures as to any required medical attention.

19. A device for obtaining heart rate comprising:

a heart rate verification module (HRVM) having a processor that performs heart rate verification, the processor receives auscultated apical heart rate data from an end user at a first heart rate monitoring device and non-apical heart rate data from a second heart rate monitoring device;

instructions of the HRVM that calculate apical and non-apical heart rate measures, calculate an acceptable heart rate range using the apical heart rate measure, and determine whether the non-apical heart rate measure falls within or outside the acceptable heart rate range;

a display screen having at least first and second indicators, a first window for displaying the apical heart rate measure, a second window for displaying non-apical heart rate measure, and a third window for displaying information identifying whether the non-apical heart rate measure falls within or outside the acceptable heart rate range, the display screen viewable by medical personnel for taking immediate action and providing the patient with medical attention if necessary, whereby when the non-apical heart rate measure falls within the acceptable heart rate range the first indicator activates to alert the medical personnel that the non-apical heart rate measure is a reliable measure of a true heart rate, and when the non-apical heart rate measure falls outside the acceptable heart rate range the second indicator activates to alert the medical personnel that the non-apical heart rate measure is an unreliable measure of the true heart rate, and when the reliable measure of the true heart rate is obtained, validating that the non-apical heart rate remains to fall within the acceptable heart rate range such that it continues to be the reliable measure of the true heart rate.

20. A system for obtaining heart rate comprising:

first and second heart rate monitoring devices for respectively obtaining apical heart rate data and non-apical heart rate data;

a heart rate verification module (HRVM) having a processor that performs heart rate verification that receives the apical heart rate data and non-apical heart rate data;

instructions of the HRVM that calculate apical and non-apical heart rate measures, calculate an acceptable heart rate range using the apical heart rate measure, and determine whether the non-apical heart rate measure falls within or outside the acceptable heart rate range;

a display screen having at least first and second indicators, a first window for displaying the apical heart rate measure, a second window for displaying non-apical heart rate measure, and a third window for displaying information identifying whether the non-apical heart rate measure falls within or outside the acceptable heart rate range, the display screen viewable by medical personnel for taking immediate action and providing the patient with medical intervention if necessary, whereby when the non-apical heart rate measure falls within the acceptable heart rate range the first indicator activates to alert the medical personnel that the non-apical heart rate measure is a reliable measure of a true heart rate, and when the non-apical heart rate measure falls outside the acceptable heart rate range the second indicator activates to alert the medical personnel that the non-apical heart rate measure is an unreliable measure of the true heart rate, and when the reliable measure of the true heart rate is obtained, validating that the non-apical heart rate remains to fall within the acceptable heart rate range such that it continues to be the reliable measure of the true heart rate.
