Not exactly sure what data looks like. I would use groupsummary with the groupbin set the 'minute' and the methods set to 'mean' to average the data into one-minute bins. This assumes the data contains the heart rate at that second, and not just an indication of if the heart beat.

G = groupsummary(T,groupvars,method,datavars)
