LoadApneaWFDB function

Loads apnea episodes for WFDB record

Loads the information of apnea episodes and stores it into the data structure containing the beat positions and other related information

LoadApneaWFDB(HRVData, RecordName, RecordPath = ".", Tag = "APNEA", 
                verbose=NULL)

Arguments

• HRVData: Data structure that stores the beats register and information related to it
• RecordName: The WFDB file to be used
• RecordPath: The path of the WFDB file
• Tag: to include APNEA episodes
• verbose: Deprecated argument maintained for compatibility, use SetVerbose() instead

Returns

Returns HRVData, the structure that contains beat positions register and other related information and apnea episodes information

Note

An example including all the steps to download a record from Physionet and load its content and the Apnea annotations is included below:

dirorig <- "http://www.physionet.org/physiobank/database/apnea-ecg/"

files <- c("a01.hea", "a01.apn", "a01.qrs")

filesorig <- paste(dirorig, files, sep = "")

for (i in 1:length(files))

download.file(filesorig[i], files[i])

hrv.data <- CreateHRVData()

hrv.data <- LoadBeatWFDB(hrv.data, "a01")

hrv.data <- LoadApneaWFDB(hrv.data, "a01")
