Most of the post-meal panic attacks are due to arrhythmias caused by disturbances in the electrical activity of cardiac muscle cells caused by myocardial ischemia. Myocardial ischemia is easily induced after meals, especially in the state of satiety, which is due to the relative shortage of blood supply to the heart and cerebrovascular system caused by the stagnation of blood in the gastrointestinal tract after meals, resulting in corresponding symptoms such as myocardial ischemia and cerebral insufficiency of blood supply, and patients may experience angina pectoris and arrhythmia, which may manifest as chest pain, palpitations and abnormal shortness of breath, and patients may also manifest as sleepiness and drowsiness, mostly due to The redistribution of blood after meals leads to a relative lack of blood supply to the cardiovascular and cerebrovascular systems, which in turn produces the corresponding phenomenon.
