Unknown annotations MIT-BIH Polysomnographic Database #94

Open mpbrigham opened 5 years ago

Hello,

The page "MIT-BIH Polysomnographic Database: Signals and Annotations" this dataset does not include the meaning for symbol "M" that is present in the annotation files. How to interpret this symbol?

Cheers,

marco

Hello, This might be a late reply but I hope it helps someone! https://physionet.org/physiobank/database/html/mitdbdir/intro.htm M means Missing beat

Does anyone know what "+" means? it is present in the annotations but, visually, it doesn't seem to refer to a beat, but more of a signal peak

Thanks
