There are usually the following two cases of rapid heartbeat after eating: 1. Natural phenomenon: With the increase of heart load and intestinal load after eating, it will cause the blood circulation to accelerate, resulting in a faster heartbeat. In this state, the heartbeat will not accelerate too drastically and there will be no uncomfortable symptoms such as panic and chest tightness; 2. Pathological phenomenon: there may be a large fluctuation of heart rate, there may be uncomfortable symptoms such as panic and chest tightness, and there will be corresponding changes of myocardial ischemia and tachycardia in the electrocardiogram examination. Therefore, when discomfort such as chest tightness and panic often occurs after meals, it is necessary to go to the hospital for ECG examination in time to exclude pathological states, and to carry out reasonable medication and reasonable treatment under the guidance of doctors.
