ECG Module impressions. Useless device

I already wrote about poor documentation(
Now, I tested acquisition speed of the device.
Maximum data rate(DisplayECG() - OFF, delay(5) - OFF) is 66Hz.
And it could not be increased without changing onboard STM32 FW.
This uC acts as BLACK BOX. No description, no source code.
DisplayECG() - ON, delay(5) - OFF - 45Hz
Any serious ECG measurements started with data rate at least 250Hz.
Initially, I planned to use it with IR pulse sensor for Blood Pressure estimation. Obviously, with 15 mS accuracy it is impossible.
