Abstract

To assess left ventricular function before and after isometric stress in a group of 10 athletes and 10 volunteers used as controls, we performed echocardiographic automated border detection (ABD) technique during handgrip maintaining 25% maximal force at least 4 min. Simultaneously, we evaluated Doppler left ventricular filling parameters, such as peak flow velocities in early diastole (peak E) and during atrial systole (peak A), E/A ratio, and deceleration time of E. From ABD waveform we calculated for systolic function: left ventricular end-diastolic and end-systolic volumes, ejection fraction, and peak ejection rate; for diastolic function we considered: peak filling rate (PFR) and time to PFR (TPFR). Peak ejection rate and PFR were normalized for end-diastolic volume. During handgrip, heart rate and systolic blood pressure significantly increased in athletes (heart rate 98 ± 5 vs 61 ± 7 b/min, p
