Spinal Cord Injury: When the spinal cord is injured, the sympathetic and parasympathetic nervous system can also be damaged. This segment of the nervous system is assigned to control heart rate and pressure. There is also no neural feedback or control from the rest of the circulatory system resulting in wide swings, especially drops, in blood pressure.
