Arrhythmia is a common and frequently occurring disease in clinical practice, primarily caused by various organic heart diseases. Common heart diseases include coronary heart disease, congenital heart disease, rheumatic heart disease, pulmonary heart disease, severe myocarditis, and cardiomyopathy, all of which can lead to arrhythmias that are generally severe. Arrhythmias can also occur in some healthy individuals due to instability of the autonomic nervous system. This type of arrhythmia can be clinically cured through lifestyle adjustments, appropriate exercise, and improvements in myocardial contractility and conductivity.

What medicine to buy for arrhythmia?

Arrhythmia encompasses a large category of diseases, including sinus tachycardia, bradycardia, sick sinus syndrome, as well as atrial fibrillation, flutter, premature atrial contractions, supraventricular tachycardia, premature ventricular contractions, and atrioventricular block, among others. Due to the various types of arrhythmias, the medications used also differ. It is necessary to go to a hospital for a clear diagnosis to determine the specific type of arrhythmia before using appropriate anti-arrhythmic drugs. Some arrhythmias cannot be resolved just by medication; for instance, in cases like pacemaker syndrome, a pacemaker needs to be installed. Additionally, patients with atrial fibrillation who have tachy-brady syndrome also require a pacemaker. Therefore, the decision on what medication to purchase for arrhythmia should be made by a doctor.

Why does arrhythmia cause chest pain?

The causes of chest pain due to arrhythmias primarily involve all kinds of arrhythmias reducing the blood flow in the coronary arteries. Although various arrhythmias can decrease coronary blood flow, they rarely cause myocardial ischemia. However, severe arrhythmias that cause significant myocardial ischemia can result in chest pain. For patients with coronary heart disease, various arrhythmias can induce or exacerbate myocardial ischemia, which may also manifest as chest pain and shortness of breath, and in severe cases, lead to acute heart failure, acute myocardial infarction, and persistent, unbearable chest pain and tightness.

Is ventricular arrhythmia serious?

Arrhythmias are primarily divided into sinus arrhythmias, atrial arrhythmias, and ventricular arrhythmias. Among these, ventricular arrhythmias are further categorized into ventricular premature contractions, ventricular tachycardia, ventricular flutter, and ventricular fibrillation. Ventricular flutter and ventricular fibrillation are fatal types of arrhythmias. Patients generally experience loss of consciousness, generalized convulsions, and even cessation of breathing and death. If ventricular fibrillation occurs, it is imperative to immediately perform defibrillation and cardiopulmonary resuscitation, among other emergency interventions.

How to treat arrhythmia?

The treatment of arrhythmias should be based on the symptoms of the patients with arrhythmias, the type of arrhythmias, and their impact on hemodynamics. Control of arrhythmias during episodes involves removing the cause and focus of the disease and preventing recurrence, which can be divided into non-pharmacological and pharmacological treatments. Non-pharmacological treatments include methods such as eyeball compression, carotid sinus massage, pinching the nose to exhale forcefully and hold breath to reflexively excite the vagus nerve, along with electrical treatments like electrical cardioversion, defibrillation, pacemaker implantation, and ablation surgery. There are mainly four types of drugs used: sodium channel blockers; beta-adrenergic blockers; drugs selectively prolonging the repolarization process, such as amiodarone; and calcium channel blockers. However, long-term use of these antiarrhythmic drugs can have varying degrees of side effects, and severe cases can cause ventricular arrhythmias or cardiac conduction block which can be fatal. Therefore, in clinical application, it is essential to strictly control the indications, monitor for adverse reactions, and rigorously follow the doctor's orders.
