There is no direct relationship between premature heart beats and stomach disease, but alcohol consumption and pain in the stomach can trigger the development of premature beats and other conditions. For people with underlying heart diseases, such as coronary heart disease, hypertensive heart disease, valvular disease, hyperthyroidism, etc., patients with stress, anxiety, fatigue, alcohol consumption, infection, anemia, electrolyte disorders, and imbalance of acid-base balance can induce the occurrence of premature beats. For people with normal heart structure and function, staying up late, fatigue, stress, anxiety, and alcohol consumption also often trigger the occurrence of premature beats. There is no direct correlation between premature heartbeat and gastric disease, but gastric disease and pain in the stomach can indirectly cause the occurrence of premature heartbeat.
