Primary Outcome Measures

Name	Time	Method
To evaluate the effects of cardivascular physiotherapy phase I on heart rate variability (HRV) of post-AMI inpatients. The tools used by measure HRV were linear analysis (time and frequency domain) and non linear analysis ( detrend fluctuation analysis (DFA), power law scaling and DFA spectral)[The mesurements of HRV were obtained daily for 6 days.]

Secondary Outcome Measures

Name	Time	Method
To compare linear and non linear analysis of HRV[The measurements of HRV for linear and nonlinear analysis were performed daily for 6 days during the supine resting before the begining of CPP.]
