HR, heart rate; BPM, beats per minute; EDD, left ventricular end diastolic diameter; ESD, left ventricular end systolic diameter; FS, left ventricular per cent fractional shortening; EF, left ventricular per cent ejection fraction; N/A, not applicable. Values are means±SEM.

* = p<0.05 versus baseline in the same group.
