Learning that blood doping adds red blood cells to the blood, what variable in the blood does this change and how does that affect blood flow? viscosity; increase blood flow resistance; decrease blood flow viscosity; decrease blood flow O resistance; increase blood flow

A patient was admitted to the hospital with chest pains. On admission, his pulse was 110 and blood pressure was 96/64. According to his history, his normal pulse rate is usually between 80 and 88 and his blood pressure runs from 120/70 to 130/80. 1. How is it possible for a patient to have an increased heart rate and a decreased blood pressure simultaneously?
