For example, if the slow heartbeat and myocardial ischemia are caused by thyroid insufficiency, you can take thyroid hormone drugs, such as Eugenol, to increase the heart rate and improve the myocardial ischemia. If the slow heartbeat and myocardial ischemia are caused by unstable angina pectoris of coronary artery atherosclerotic heart disease, drugs such as Qishen Yiqi Dripping Pill, Heart Treasure Pill, Compound Danshin Dripping Pill or Tongxinluo Capsules or Ginseng Yangxin Capsules can stabilize the heart rate, increase the heart rate and improve myocardial ischemia to varying degrees. You can also take western drugs, such as isosorbide mononitrate or coenzyme Q10, which also have the effect of increasing the heart rate and improving the blood supply to the heart, regardless of the drug of choice before the original disease should be clarified.
