Hand-held device for self-measurement and recording of a heart rate variability examination
The invention relates to a method and device for recording and presentation of physiological parameters, which can include both blood pressure and heart pulse. Information about the heart pulse is derived from a recorded blood pressure signal, whereby the need for e.g. an external ECG measurement device is eliminated. It is likewise a part of the invention that a blood pressure measurement is used for the derivation of data such as Heart Rate Variability (HRV) and/or baroreflex sensitivity (BRS) values.
1. A hand-held measurement device for facilitating patient self-measuring and recording, the hand-held measurement device comprising:
a housing, and a pressure transducer, a display, electrocardiogram (ECG) electrodes, and a processor, each of which is within the housing, the processor being configured to:
measure, via the pressure transducer, an exhalation pressure of a patient during a time period associated with an examination;
cause a first graphical component indicating the exhalation pressure measurement to be presented on the display such that the first graphical component is continuously updated in real-time, as the exhalation pressure is being measured, until at least the end of the time period associated with the examination;
cause a second graphical component indicating a remaining time of the time period to be presented on the display such that the second graphical component is continuously updated in real-time, as the exhalation pressure is being measured, until at least the end of the time period associated with the examination;
measure, via the ECG electrodes, a heart rate of the patient during the time period associated with the examination; and
calculate heart rate variability of the time period associated with the examination based on the heart rate measurement and cause a graphical component indicating the heart rate variability to be presented on the display.
2. The hand-held measurement device according to claim 1 , wherein the processor is further configured to:
measure, via the pressure transducer, a blood pressure of the patient during the time period associated with the examination.
3. The hand-held measurement device according to claim 1 , wherein the processor is further configured to:
measure, via the pressure transducer, a hand grip squeeze pressure of the patient during the time period associated with the examination.
4. The hand-held measurement device according to claim 1 , further comprising a baroreflex sensitivity recording unit.
5. The hand-held measurement device according to claim 1 , further comprising a plurality of push buttons configured to provide control signals to the processor.
6. The hand-held measurement device according to claim 1 , wherein the hand-held measurement device is adapted to simultaneously measure pressure and ECG signals.
7. The hand-held measurement device according to claim 1 , wherein the processor is further configured to:
cause step-by-step instructions for using the hand-held measurement device to perform patient self-measuring to be presented on the display during the examination and prior to the time period associated with the examination.
8. The hand-held measurement device according to claim 1 , wherein the processor is further configured to:
cause step-by-step instructions for using the hand-held measurement device to perform patient self-measuring to be presented on the display prior to and during the time period associated with the examination.
9. The hand-held measurement device according to claim 1 , wherein the processor is further configured to:
cause one or more results of the examination to be presented on the display subsequent to the time period associated with the examination.
