% ecgBag.tar is a collection of ECG processing algorithms for use
% with Matlab mostly by Gari Clifford and available under the GNU
% public license (see bottom of this file).
%
%
% They are not intended as optimal algorithms, but they're not bad.....
% Please don't blame me if anything goes wrong - but feel free to
% email me and ask questions, which I'll answer if I have time
% Gari Clifford (gari@ieee.org)
%
% calc_lfhf.m - calculates the LF/HF ratio, LF and HF metrics
% lomb.m - calculates the Lomb-Scargle periodogram(周期图)
% (PSD for unevenly sampled signals)
% rpeakdetect.m - finds R peaks in ECG - see rrextract(寻找r)
% rrextract.m - runs over rpeakdetect to extract RR intervals(rr间期)
% clean_hrv4.m - removes abnormally timed beats
% clean_RR_RS.m - removes abnormally timed & shaped beats
% example.m - an example file to run all this
% maxjiggle.m - finds peaks if the fiducial point(基准点) is slightly off
% interp_RR.m - interpolates an unevenly sampled signal by your favourite
% (ad hoc) method. NOT recommended - it just introduces
% errors into a PSD calculation - use the Lomb-Scargle
% method, it's so much better.
% filterECG256Hz.m - ECG, 256Hz, Least Sq. FIR LP & HP filters
% (cascaded) 70dB 0.05-40Hz 1dB ripple
% filterECG128Hz.m - ECG, 128Hz, Least Sq. FIR LP & HP filters
% (cascaded) 70dB 0.05-40Hz 1dB ripple
% lfhf_sliding_win.m - calculates a time series of LF/HF values by
% sliding a window across the data
% sliding a window across the data
%
% generate_rr_with_FM.m - Creates an artificial RR interval
% time series
%
% down_sample_realistically.m - takes an evenly sampled time series
% and extracts a plausible (irregularly
% sampled) RR interval time series
% ECGfilterTimeAlignedSVD.m - uses a QRS detector and SVD to filter ECG
% select_train.m - makes a matrix of fiducual point centered
% P-QRS-T complexes.
% recon_ECG.m - unwraps a matrix of fiducual point centered
% P-QRS-T complexes into a 1-D signal
% svdFilter.m - filters data using SVD - variant of ECGfilterTimeAlignedSVD.m
% wienerFilter.m - Wiener filtering for the ECG(维纳滤波)
% plotWiener.m - plots the spectral response of wienerFilter.m
% wavelet_decompose.m - A wavelet filter for ECG analysis by Nick Hughes
% wabp.m - James Sun's version of Wei Zong's wabp.c (on www.physionet.org)
% (i.e. - a QRS detector for blood pressure signals)
%
% snr.m - calcualtes the signal to noise ration in dB
%
% conv_norm_annot.c ... this C-prog parses the output of the WFDB
% rdann program to extract the Normal to Normal intervals and puts
% it in a readable format for Matlab - read the header for details
% conv_sleep_annot.c ... as above, but works on sleep staging...
% - again, read the header for details, and type:
% type readme
%
% This software is offered freely and without warranty under the
% GNU public license. Please don't blame me if anything goes wrong :)
%
% gari@ieee.org
% for the polysomnographic DB, you would run rdann as
% rdann -r slp02a -a st
% and it spits out the data to stdout .. . so best to do -
% rdann -r slp02a -a st > fileout.dat
% (note that you must have the data on a current path to do this).
%
% put simply:
% rdann -r slp01a -a st > slp01a.ascii
% conv_sleep_annot slp01a.ascii slp01a.tRnKart > log1
% rdann -r slp01a -a ecg > slp01a.tmp
% conv_norm_annot slp01a.tmp slp01a.bts > log2
%
% slp01a.tRnKart should be a 3 column file of [time_stamp sleep_stage other_label]
% slp01a.bts should be a 2 column file of [time_stamp beat_label]
%
% The time stamps are in seconds since the beginning of the file
% (so check your sampling frequency is the same as the #define in the C file).
%
% The sleep stage are:
% -1 W subject is awake
% 0 R REM sleep
% 1 1 sleep stage 1
% 2 2 sleep stage 2
% 2 2 sleep stage 3
% 4 4 sleep stage 4
%
% The other labels are
% -0.1 No label in 3rd column
% -2 H Hypopnea
% -0.2 HA Hypopnea with arousal
% -3 OA Obstructive apnea
% -0.3 X Obstructive apnea with arousal
% -4 CA Central apnea
% -0.4 CAA Central apnea with arousal
% -5 L Leg movements
% -0.5 LA Leg movements with arousal
% -0.6 A Unspecified arousal
% -10 MT Movement time
%
% The beat labels are
% 1 == normal
% 2 -> 19 == abnormal/ectopics
% 2 = L
% 3 = R
% 4 = B
% 5 = A
% 6 = a
% 7 = J
% 8 = S
% 9 = V
% 10 = r
% 11 = F
% 12 = e
% 13 = j
% 14 = n
% 15 = E
% 16 = f
% 17 = Q
% 30 and above == artefact
% 20 -- unspecified (\?)
% 25 -- paced (P)
% 0 -- error - classification not recognized

% Change Log
% ----------
% Robert Tratnig at Graz Uni added the following comments and changes:
%
% clean_hrv_4.m:
% I have added a line that says "stp=0;".
% I call this line "38".
% According to this indication I added lines 38,39,40,43,44,45,47,50,51,82.
% Additionally I have altered line 40 (I added a condition: "(stp==0) & ".
%
% The same scheme I have applied to clean_RR_RS.m
% Here I call the line that says "stp=0;" line "51".
% In that context I added lines 51,52,53,56,57,58,60,61,62,102.
% Also here I have altered a line: 54 (I added a condition: "(stp==0) & ".
%
% I have to do this because of the following reason:
% When analyzing the file cu06.dat of the Creighton University Databank (CU_DB)
% in the MIT-data collection, the parameter transfered to this function
% clean_hrv4.m and clean_RR_RS.m (temp_hrv) was just a 3 rows long array of 2
% columns. Additionally no row satisfied the condition of the while loop, so I
% had an error called "Index exceeds matrix dimensions".
%
% Many thanks for that Rob!
%
%
%
% ToDo
% ----
%
% - vectorise lomb.m ... currently very slow. this code was emailed to
% me sometime in the past by a colleague who obtained it freely from the
% internet. I have made minor modifications but have so far failed to have
% time (or sufficient reason) to vectorise it (lomb.c does the job!)
%
% - Add optimisation routine to make either end of RR tachogram window
% have same mean and gradient within a tolerance as per Schreiber's
% surrogate window matching.
