Erratic Heart Rate Data #12

Open sarahblandduke opened 4 years ago

sarahblandduke commented 4 years ago

Hello!

My team is attempting to use the breakout board/shield to take a semi-accurate heart rate, but what we see printing to the Arduino is extremely variable and not at all accurate (skips wildly between 0 bpm, ~50 bpm, and ~120 bpm even at rest with little motion).

1) Is there some sort of initialization we need to do before we start running the program to reset?

2) Do you have any further advice on EKG placement, specifically for women? Should the driven leg lead be placed nearer to the hip or the waist?

Please let me know if any other information would be helpful.

Dear Sarahblandduke,

Please find the answers to your questions below,

  1. Just run the code that initializes itself and when you see the output in the GUI, there will be a settling time of up to 30 seconds, and then the ECG and the heart rate should be stable.

  2. Please refer the attached image for electrode Placement. Place the electrodes as shown in the image and also try to place the electrodes in different positions nearby in order to obtain an exact position for accurate measurements.

If the ECG is not correct the heart rate will be wrong. So please check and send some screenshots of the ECG waveform shown in the GUI to help us better understand and resolve your issue.

For any queries, you can write to sales@protocentral.com. All your queries will be resolved by our technical team.
