If a patient has panic after quitting smoking, it is usually because of previous dependence on nicotine or tar components, so a transient withdrawal reaction occurs after quitting smoking, which can be relieved by the following ways: 1. Do some outdoor exercise, and aerobic exercise is recommended to adjust the heart rate by means of aerobic exercise, but the amount of aerobic exercise should not be too large. 2. Relieve panic by taking smoking cessation candy, etc. 3.If the heart rate is too fast, reaching 100 times/minute, or even above, a small amount of beta-blockers, such as metoprolol tartrate, etc., can also appropriately relieve the heartburn that occurs after quitting smoking.
