MATLAB: How to calculate heart rate from RR interval matrix

MATLAB

Hi, I have RR intervals matrix and I want to calculate the heart rate bpm?

Best Answer

Convert the R-R intervals into individual rates, then calculate the mean.

Example —

RR_Vct = rand(15,1);                        % R-R Intervals In Seconds
HR_Mean = mean(1./RR_Vct);                  % Mean Heart Rate

MATLAB: What assumptions are made in computing Bit Error Rate (BER) and confidence intervals with the BERCONFINT function in Communications System Toolbox

The BERCONFINT function calls the BINOFIT function, which uses the Clopper-Pearson interval to calculate confidence intervals. This is shown at the following link:

MATLAB: Heart Rate by category

One approach:

[~,sc] = xlsread('Sérgio Querido TEST.csv');
t_rc = regexp(sc(2:end), ';','split');
dn = cellfun(@(x) datenum(x(:,1), 'HH:MM:SS'), t_rc);
hr = cellfun(@(x) str2double(x(:,2)), t_rc);
bin_vct = [0  50  100  200];
hc = histcounts(hr, bin_vct);
fprintf(1, '\n\tRate\t0-50\t50-100\t100-200\n')
fprintf(1, '\tSecs\t%4d\t%6d\t%7d\t\n\n', hc)
  Rate  0-50  50-100  100-200
  Secs     3     320        0
