If the patient experiences tachycardia accompanied by hiccuping, it may indicate an early-stage digestive system disorder. It is recommended for the patient to consume a light diet, eat smaller, more frequent meals, especially avoiding spicy and irritating foods, and to regularly undergo gastroscopy. Care should be taken with consuming spicy and irritating foods, and it is also advisable to regularly undergo electrocardiogram (ECG) check-ups at the hospital. Sometimes, the ECG may show signs of angina or myocardial ischemia, which can lead to excessive secretion of stomach acid and subsequently cause hiccuping. Additionally, a gastroscopy should be done to further clarify the diagnosis.
