What medicine does treatment atrial fibrillation take

summary

Atrial fibrillation is very common in the elderly, and most of these people are accompanied by arrhythmia. Therefore, in the treatment, the method of drug treatment is the best. This article will introduce the drugs for the treatment of atrial fibrillation to you.

What medicine does treatment atrial fibrillation take

Drug 1: non dihydropyridine calcium channel blockers. These drugs can also slow down heart rate and myocardial contractility by blocking calcium channels. Commonly used drugs include diltiazem (trade name hexingshuang or Hebeishuang) and verapamil (trade name verapamil). Both of them have common and sustained-release dosage forms. These drugs also have the side effects of bradycardia. They can not be used in patients with bradycardia or conduction disorders, and they are also prohibited Patients with decompensated heart failure and atrial fibrillation combined with preexcitation.

Drug 2: digitalis. Different from the former two kinds of drugs, this kind of drugs not only does not weaken the contractility of the myocardium, but also enhances it. Originally used for the treatment of heart failure, digoxin has a long history. Digoxin is an oral preparation, while cedilanide is commonly used as an intravenous preparation. This kind of drugs can control the heart rate of atrial fibrillation at rest, but the effect on the heart rate during activity is not good. Sometimes cedilanide is short-term Although oral digoxin can improve symptoms to a certain extent, it can not improve prognosis in the long term. It has retired to the second line of heart rate control of atrial fibrillation. It is only used for some patients with poor cardiac function or as a combination of the above two drugs when the effect is insufficient, and the dosage is appropriate Small. During medication, the blood drug concentration needs to be monitored to avoid poisoning. When this kind of drug poisoning occurs, gastrointestinal symptoms such as anorexia and nausea can also appear. People who are in serious condition may also have new arrhythmias. Therefore, during medication, if the above symptoms are found, they need to see a doctor in time.

Drug 3: beta blockers. These drugs are the most commonly used drugs to control the ventricular rate of atrial fibrillation, and the effect is also the best, especially for the control of heart rate during activity. Beta blockers play a role by blocking the beta receptor of the heart. In addition to slowing down the heart rate, they can also weaken the contractility of the heart, help the myocardium rest, and have a certain antihypertensive effect. Therefore, for patients with heart failure, coronary heart disease or cardiomyopathy, they also have the effect of improving the prognosis. Their onset and metabolism in vivo are relatively fast, and they are relatively safe. Common drugs and usage are shown in the table below. The common side effect of this kind of drugs is bradycardia, which is related to the dosage of drugs. At the beginning of medication or early adjustment of dosage, attention should be paid to monitoring the heart rate. Some people may also have side effects of fatigue, which are generally not serious. If young people can not tolerate it or need to work, they can consider switching to other kinds of drugs. According to the principle of drug action, patients with slow heart rate (bradycardia), severe atrioventricular block or long intermission should not be used, and patients with heart failure should not be used until heart failure is controlled. In addition, these drugs may cause bronchospasm, and can not be used when the airway spasm is very serious or the asthma attack is not controlled.

matters needing attention

Atrial fibrillation in the usual treatment of the disease, you can often choose the above drugs, and in peacetime, they also pay attention to frequent physical exercise, according to their own circumstances can be appropriate fitness, the elderly can be some relaxed and pleasant without increasing the burden of the heart of systemic activities, such as Taijiquan, fish, flowers, walking, health exercises, qigong, etc.
