<prompt> All of the following cardiovascular physiological changes occur in pregnancy EXCEPTIncreased cardiac outputIncreased heart rateIncreased stroke volumeIncreased systemic vascular resistance  <response>: D Increased systemic vascular resistance Physiological Changes seen in Cardio-Vascular System in Pregnancy: Raised pulse rate by about 10 beatsmin. Lateral upward displacement of apex. Exaggerated splitting of first heart sound. Systolic murmur intensifying during inspiration. Decreased arterial blood pressure vascular resistance. Increased cardiac output more in lateral recumbent position.
