Sudden thumping of the heart may be due to premature beats, atrial fibrillation, hyperthyroidism and other causes.
1. Premature beats: Sudden thumping of the heart may be caused by premature beats. Premature beats are a common clinical symptom that can occur in both normal people and patients with heart disease. If you don’t feel anything, it is probably just a normal physiological phenomenon. If you have basic cardiovascular disease and the ECG reveals premature beats, accompanied by panic, shortness of breath and other uncomfortable symptoms, you must be treated.
2. Atrial fibrillation: Coronary heart disease, high blood pressure, or drinking a lot of alcohol, overwork, etc. can cause atrial fibrillation. The main manifestation is irregular heartbeat, the most common symptom is panic, some people also feel chest tightness, shortness of breath or sweating. Some people have no obvious symptoms, but only found by chance during physical examination, this kind of “asymptomatic atrial fibrillation” is usually more dangerous.
3. Hyperthyroidism: Hyperthyroidism, due to increased basal metabolic rate, accompanied by sympathetic hyperfunction, can cause the heart rate to accelerate, then the heart will suddenly thump. It is recommended that the patient improve the thyroid function, thyroid autoantibodies, thyroid ultrasound and other tests to clarify the diagnosis.
There may also be other causes, we recommend that the patient go to a regular hospital to improve the 24-hour dynamic electrocardiogram and other tests to clarify the cause of the disease.
