Answer:

Check the explanation

Explanation:

Harold's tachycardia is the result (sign) caused as a result of his chronic gastritis. His gastritis damages his capability to produce intrinsic factor and then to soak in vitamin B12. The short levels of this very essential vitamin are the cause of his anemia. Harold's anemia condition means that his tissues are weakly oxygenated.

Harold's amplified heart rate (tachycardia) is his body's reaction to the low level of oxygen.
