ECG Module code

Please help me understand your code for this module
I got this module to work on a m5stack Fire but I would like an explanation of the library program, ECG.ino at:
There are no comments in the code which makes it hard to follow the program.
There is also no data dictionary for the following terms:
Difficult to understand constructs
What does the following do?
ECGdataFSM = ( data == 0xAA ) ? ECG_DATA_LENGTH : ECG_IDLE;
DataMAX = ( ECGData > DataMAX ) ? ECGData : DataMAX;
DataMIN = ( ECGData < DataMIN ) ? ECGData : DataMIN;
The documentation for this product at https://docs.m5stack.com/#/en/module/ecg?id=related-link
states that the MPU STM32 in the module supports a heart rate statistics algorithm. What does this algorithm do? What parameters does it use?

@dsrc12: I have now got this to work and it works best if I discount the USB link to Fire. The code I had difficult understanding is based on a C++ Ternary Operator in C. Returns either ECG_Data_LENGTH if data equals 0xAA or ECG_IDLE if false. At least this is a start. Still need to decode the meaning of the parameters.
