Wang, male, 45 years old. High fever from influenza caused heart palpitations and irregular pulse for 4 months. Diagnosed as "viral myocarditis with frequent ventricular premature beats (bigeminy)" by a city hospital, switched to Chinese medicinal treatment on March 11, 1993. At the time of consultation, palpitations occurred intermittently, worsened with slight exertion, often felt chest tightness at night, accompanied by irritability and insomnia, dark red tongue with thin white coating, and a fine, choppy, and knotted pulse. This is due to warm pathogens invading the lungs and affecting the heart, injuring heart yang and causing heart vessel obstruction. Treatment should focus on warming and tonifying heart yang, and tonifying qi to unblock the vessels.
