Why is my heart rate not coming down after exercise?
If your heart rate doesn’t appropriately drop after you stop exercising, it can indicate poor cardiovascular fitness or, in extreme cases, even a medical condition that is affecting your autonomic nervous system.
What happens if your heart rate is elevated for too long?
But if left untreated, some forms of tachycardia can lead to serious health problems, including heart failure, stroke or sudden cardiac death. Treatment for tachycardia may include specific maneuvers, medication, cardioversion or surgery to control a rapid heartbeat.
What causes persistent elevated heart rate?
Possibilities include anemia, an underlying infection, elevated thyroid hormone, or reaction to medication. Addressing those conditions would likely bring the heart rate back to a normal rate. Other factors may be involved, too, such as overdoing caffeine.
