Atrial repolarization Study guides, Class notes & Summaries

allows blood to flow directly from the right atrium into the left atrium to bypass pulmonary circulation - foramen ovale carries blood from the umbilical vein to inferior vena cava; allows some blood to bypass the liver - ductus venosus atrial contraction; systole; p wave - atrial depolarization max volume of air that can be exhaled following maximal inhalation - vital capacity allows blood in pulmonary artery to flow directly into the descending aorta to bypass the pulmonary circula...

Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) Correct Answers A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known...

Describe treatment of dysrhythmias correct answer: To determine if treatment is necessary, assess the patient. Then ask the following questions: Is he or she experiencing signs and symptoms of decreased cardiac output? Is the dysrhythmia potentially life threatening? If the answer to either of these questions is yes, the patient will need to treatment for the dysrhythmia. ***WE WILL DISCUSS TREATMENTS OF DYSRHYTHMIAS BASED UPON CURRENT ACLS TREATMENT ALGORITHMS CLINICAL MANIFESTATIONS ...
