Sudden thumping of the heart for a while and then normal may be caused by physiological factors or pathological factors such as paroxysmal atrial fibrillation, myocardial ischemia and other causes. General treatment, medication and surgery should be given according to the specific cause. 1. Physiological factors: Sinus tachycardia may be caused by shock or emotional excitement, excessive alcohol consumption, which may lead to a sudden thumping of the heart for a while and then normal, which usually does not require special treatment, attention to rest, calm down, reduce alcohol consumption can alleviate the symptoms. 2. Pathologic factors. This condition can be treated with medications such as metoprolol, warfarin, and aspirin under a doctor’s supervision. Severe symptoms can also be treated with radiofrequency ablation. Myocardial ischemia: During an episode of myocardial ischemia, the heart may suddenly thump due to an increase in myocardial oxygen consumption and a reflexive increase in heart rate, which will quickly return to normal as myocardial ischemia improves. This condition can be treated with medications such as Rosuvastatin Calcium Tablets and Atorvastatin Calcium Tablets under the guidance of a doctor. If the condition is more serious, it can be treated with interventional procedures such as PCI stenting. If your heart suddenly beats normally again, we recommend you to go to a regular hospital to have a checkup, and then cooperate with your doctor to have a targeted treatment after the cause is clear.
