causes of feeling of rapid heartbeat
A bounding pulse is also a common response to stress and anxiety, so if you are experiencing (for example) extra stress at work or anxiety over a bill, you might feel a bounding pulse. Drinking caffeine and taking stimulants (such as those in asthma medication) can also cause your pulse to speed up.
Less Common Causes of a Bounding Pulse. Less common but more serious conditions could potentially be the cause of your bounding pulse. An overactive thyroid, which causes a condition called hyperthyroidism, may cause your bounding pulse. Your thyroid gland controls your bodyâs metabolism.
