Patients who experience an accelerated heartbeat the day after drinking alcohol do so because the process of gradual absorption and decomposition of alcohol in the body causes sympathetic excitation, which in turn leads to an accelerated heartbeat. If there is an accelerated heartbeat and the patient has symptoms such as chest tightness, shortness of breath, panic, palpitations, etc., the patient should pay attention to it and should go to the hospital in time to give timely treatment through electrocardiogram, cardiac ultrasound, coronary CTA, coronary angiography, doctor’s examination and laboratory tests to clarify other causes of the accelerated heartbeat. If the heartbeat is accelerated severely, you can also take some drugs to control the heart rate, and through systematic treatment, the patient’s symptoms can be gradually relieved.
