Arrhythmia refers to the abnormal origination or conduction of impulses in the heart due to abnormal activation of the sinoatrial node, slow conduction, blockages, or passage through abnormal pathways, leading to abnormalities in the frequency and/or rhythm of the heartbeat. Arrhythmias are a significant group of cardiovascular diseases. They can occur alone or in conjunction with other cardiovascular diseases. The prognosis of arrhythmias depends on their causes, triggers, trends in progression, and whether they lead to severe hemodynamic disturbances, potentially causing sudden death or continuous impairment of heart function leading to heart failure.

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.

Arrhythmias include:

Arrhythmia is a very common disease in our daily life. What does arrhythmia include? Generally speaking, arrhythmia often includes the following aspects: First, irregular heartbeat, such as sinus arrhythmia, atrial fibrillation, and frequent premature beats. Second, tachycardia, such as paroxysmal supraventricular tachycardia, ventricular tachycardia, and so on. Third, bradycardia diseases, such as sinus bradycardia, severe atrioventricular block, and sick sinus syndrome, etc.

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.

Arrhythmia is what kind of disease

Arrhythmia is caused by abnormal excitation of the sinoatrial node or excitation originating outside the sinoatrial node, where the propagation of excitation is slow, blocked, or conducted through abnormal channels, leading to abnormalities in the frequency and/or rhythm of heartbeats due to origins and (or) conduction disorders of cardiac activity. Arrhythmia is an important group of diseases within cardiovascular diseases. It can occur independently or in conjunction with other cardiovascular diseases. Its prognosis is related to the causes, inducing factors, and evolutionary trends of the arrhythmia, and whether it leads to severe hemodynamic disturbances. It can cause sudden death or continuously affect the heart leading to its failure.

What medicine is used for arrhythmia?

There is still no consensus on the drugs commonly used for arrhythmia. The main classes used clinically are as follows: The first class is sodium channel blockers, which include three subclasses: moderate, mild, and significant sodium channel blockers, respectively comprising quinidine, lidocaine, and propafenone. The second class mainly consists of adrenergic receptor blockers, with propranolol being a representative drug. The third class of drugs selectively prolongs the repolarization process, among which amiodarone is commonly used clinically. The fourth class is calcium channel blockers, which mainly block calcium channels and inhibit the inflow of calcium, with verapamil being the main representative drug. Long-term use of anti-arrhythmia drugs can cause varying degrees of side effects, with severe cases possibly leading to ventricular arrhythmia or fatal cardiac conduction block. Therefore, when using these drugs clinically, it is essential to strictly control the indications, monitor adverse reactions, and strictly follow the doctor's prescription for rational medication.
