Recovery of regional systolic and diastolic myocardial function after acute myocardial infarction evaluated by two-dimensional speckle tracking echocardiography.

abstract：:We questioned whether electromyographic (EMG) signs of neuromuscular fatigue accompany the changes in respiratory variables measured at the ventilatory threshold (VTh) during exercise on a cycloergometer. This was based on the assumption that the activation of muscle afferents sensitive to accumulation of lactate and ...
