Acute left ventricular dysfunction in the critically ill.

abstract：:The purpose of our study was to determine the frequency of cardiac ectopy during the performance of flow-volume loops. The performance of an adequate flow-volume loop entails significant shifts in intrathoracic pressure and oxyhemoglobin saturation that could heighten myocardial arrhythmogenicity and lead to increased...
