Exercise is protective against ventricular arrhythmias induced by ischemia (I), the condition of inadequate blood flow, and reperfusion (R), the reestablishment of blood flow. This protection is observed clinically and scientifically by decreased incidence in ECG abnormalities. Numerous scoring systems exist for the quantification of ventricular arrhythmia severity. On the ...

Expiratory positive airway pressure (EPAP) is a form of noninvasive positive-pressure ventilatory support that, in spite of not unloading respiratory muscles during inspiration, may reduce the inspiratory threshold load and attenuate expiratory dynamic airway compression, contributing to reduced expiratory air-flow limitation in patients with COPD. We sought to determine the ...
