Hi,
I have nrf51dk and analog EKG sensor. I know that ble_app_hrs allows to get R-R interval, but in my application i need to get also R-S and R-T intervals (or just R, S and T timestamps) and send it over BLE.
My questions are:
- What kind of algorithm is used to convert analog signal from sensor into digital?
- Is the resulting digital signal accurate enaugh to get R,S and T timestamps? (for example, if my analog signal would look like in the picture above, how would look digital signal retrieved from it - will all the meaning peaks be possible to catch?)
- Is it possible to write such application by just modifying ble_app_hrs example?
Thank you in advance for any help with this issue.
