Sympathetic Nervous System

1. stiumlation of alpha receptors

1.1. increase vasoconstriction

1.1.1. increase workload of heart

2. decreased blood pressure will stimulate baroreceptors and osmoreceptors

3. .

3.1. activation of beta receptors

3.1.1. increase heart rate

3.1.1.1. increase MV02 possibly causing more myocardial damage

3.1.1.1.1. lower cardiac output

3.1.2. increase stroke volume

4. sodium retention

4.1. water retention

4.1.1. increase preload

4.1.1.1. increase myocardial consumption
