The Oriented Is Instructed To Reposition The Patient To Try And Correct The Problem. The Cardiac Monitor Most Likely Demonstrates? [Correct Ans Is: - Failure To Capture (Pacemaker Without A Qrs) May Be Corrected By Repositioning The Patient To The Side. The Patient With Diastolic Heart Develops Svt, Heart Rate 220/Min. The Most Dangerous Hemodynamic Effect Is A Decrease In: [Correct Ans Is: - Coronary Artery Perfusion. Diastolic Heart Failure Results In A Problem With Left Ventricular Filling Secondary To Ventricular Thickening, And Contractility And Ejection Are Maintained In Diastolic Failure. The Rapid Heart Rate Will Decrease Filling Time, Worsen Left Ventricular Filling And Because Coronary Artery Perfusion Occurs During Diastole, This Arrhythmia May Be Life-Threatening. The Patient Is Receiving Heparin Infusion For The Treatment Of Pulmonary Embolism. There Has Been A 60% Decrease In The Platelet Count And No Clinical Change. Which Of The Following Is Indicated?
