The patient’s upset stomach may cause symptoms of panic and palpitations. Discomfort in the stomach may cause symptoms such as nausea, vomiting, and poor nausea, which in turn may cause hypokalemia, which in turn may cause panic and palpitations. Clinically, it is also common to see elderly people complaining of stomach discomfort, as well as panic and palpitations, often mistaking them for stomach disorders and neglecting the treatment related to heart disease. Stomach discomfort causing panic and palpitations may be due to pain in the stomach, which causes increased sympathetic excitability and faster heart rate. In addition, angina pectoris, which radiates to the upper abdomen and stomach, can occur in patients with heart disease. When upper abdominal discomfort occurs, one needs to be alert to the occurrence of myocardial infarction originating from the right coronary artery and accompanied by nausea, vomiting, cold sweats, decreased blood pressure, shock, and heart failure.
