This is an assigment and if possible just want to make sure if my work is correct, I’m especially unsure about the graphs.
We’re given and ECG signal (that’s supposed to be of a healthy person) and have to find:
Detect QRS complex. (output:waveform)
Heart Rate. (output:numeric)
Respiratory Rate. (output:numeric and graphical)
Heart Rate Variability. (output:waveform)
Sampling frequency is given as fs=500Hz.
I’ve attached the ECG signal and the code functions I used.
This is the main code used to call the functions:
% Load data
matstruct = load(‘ECGdata.mat’);
ecg = matstruct.x;
fs = 500; % Sampling frequency
t = (0:length(ecg)-1)/fs;
gr = 1;

% Detect QRS complexes
[qrs_amp_raw, qrs_i_raw, delay] = pan_tompkin(ecg, fs, gr);
QRS=pan_tompkin(ecg, fs, 0);

Results:

% Calculate Heart Rate
avg_heart_rate = calculate_heart_rate(ecg, fs, gr);
Output: Average Heart Rate: 66.96 bpm
(note: avergae herat rate is between 60 and 100 beats per minute.)
% Calculate Respiration Rate
[resp_rate, resp_signal] = calculate_respiratory_rate(ecg, fs, qrs_i_raw);
Output: Respiration Rate: 16.9997 breaths per minute
(not: avergae respiratory rate are between 12-20 breaths per minute for an adult.)

% Calculate Heart Rate Variability
HRV = calculateHRV(QRS, fs);This is an assigment and if possible just want to make sure if my work is correct, I’m especially unsure about the graphs.
