In plateau reaction, accelerated heartbeat is one of the common phenomena, the specific relief methods are as follows: 1, you can take heart rate stabilizing drugs, such as beta-blockers can play a role in relieving the effect of ventricular rate, such as betalactam, metoprolol tartrate and other drugs can play a role in relieving the effect of tachycardia after plateau reaction. 2, the heartbeat of plateau reaction is usually caused by myocardial ischemia. The heart will naturally improve after improving the blood supply to the heart, you can take drugs such as salvia, safflower, rhodiola, etc. can relieve the symptoms of myocardial ischemia. 3, the lack of oxygen in the plateau reaction is also a significant cause of the accelerated heart rate, you can take drugs to supply oxygen to the heart, such as coenzyme Q10, etc. can also relieve the accelerated heart rate. 4, oxygen is also a way to relieve the accelerated heart rate.
