What happens when your heart rate is high?

High heart rate patients may appear symptoms usually include high blood pressure, hypoxia, syncope, etc., the specific analysis is as follows:

1. High blood pressure

may lead to increased sympathetic excitability, and catecholamine secretion will also become more, leading to increased blood pressure.

2. Hypoxia

High heart rate may lead to insufficient cardiac output, leading to tissue ischemia and hypoxia.

3. Syncope

High heart rate will lead to faster heartbeat, so that the output of the heart decreases, resulting in insufficient blood supply to the brain, resulting in syncope.
