D) DECREASES PRELOAD AND DECREASES MYOCARDIAL 02 DEMAND
Nitrate Cause Venodilation, Which Results In A Decrease In Venous Return To The
Heart (Left Ventricular Preload Reduction). The Decrease In Preload Decreases The
Work Of The Left Ventricle And Myocardial Oxygen Demand
All Of The Following Support The Diagnosis Of Cardiac Tamponade EXCEPT:
A) WIDENING PULSE PRESSURE
B) Equalization Of Right And Left Heart Pressures
