Hi Mak,
in future, pls avoid using CAPITAL letters while writing in the forums. there are different styles of writing like smiley, used to express the moods/emotions . wrinting in CAPITAL letters are considered rude.

always, pls explain your project / intentions first before posting the query, so that people can understand your query well (also in proper context).

back to your query,

i understand from your posting, that you are trying to make a ECG arrythmia monitor using 80xx. it is possible to do a "heart rate" related arrythmia monitoring using 80xx. but shape related analysis in real time is out of question for a 80xx due to its processing capabilities.
