I have plotted this raw ECG text file from Opensignals programm on Matlab, but I want to filter it, any help? response will be appreciated.

% extract data
data = readmatrix('opensignals_98d391fd3f18_2020-05-12_viseuellentrainig', ...
    'HeaderLines', 3, 'ExpectedNumVariables', 6);

% plot 6th column
plot(data(:,6))
xlabel("Zeit [ms]",'FontSize',20);
ylabel("Spannung [mV]","FontSize",20);
hold on
