Premature beats associated with myocardial ischemia can be controlled by the following drugs: 1) Chinese medicine to stabilize the heart rate, such as heart stabilizing pellets taken orally, and other drugs such as coronary heart pills, Danshen drops, Astragalus capsules, and Ginseng heart pellets, which can effectively improve myocardial ischemia and control premature beats. 2) Western drugs can be taken to control premature beats caused by myocardial ischemia, such as beta-blockers, such as metoprolol tartarate and metoprolol succinate, which can effectively inhibit the occurrence of premature beats. 3. Western drugs can be taken to improve ischemia and stabilize the ventricular rate, such as coenzyme Q10, which can play the above-mentioned role and effect.
