Transcript of CMBEC presentation

ECG Classification Using kNN and LDA for Continuous Heart Monitoring
Problem
Our Work's Status
Prevention is key!
Can we predict a heart problem BEFORE it happens?

What warning SIGNS are there?

How does this translate to sports PERFORMANCE TRACKING?
Is CONTINUOUS and MOBILE monitoring of the heart possible?
What happens when the heart conditions are already there and failure is "imminent"?
Again, prevention is key!
ECG database
Linear Discriminant Analysis
kNN Classifier
Results
Bigger picture
what does all of this look like?

"Many of these deaths could have be prevented if, beforehand, the victims knew their risk factors and the warning signs of an impending cardiac event."
