Pulmonary Edema
Pulmonary Edema ( 33 Questions)
Incorrect. Atrial contraction contributes to ventricular filling but is not typically the primary site of impairment in heart failure leading to pulmonary edema.
Incorrect. Ventricular relaxation (diastole) is necessary for ventricular filling, but the impaired contraction during systole is a more common issue in heart failure.
Correct. Impaired ventricular contraction (systole) in heart failure results in reduced forward flow of blood and leads to fluid backup in the lungs, contributing to pulmonary edema.
Incorrect. Electrical conduction in the heart may affect heart rhythm but is not directly related to the development of pulmonary edema.
