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.

Can arrhythmia be cured?

There are many types of arrhythmia, some of which, like sinus tachycardia, sinus bradycardia, occasional premature atrial contractions, premature ventricular contractions, and premature junctional contractions, can also occur in healthy individuals and usually do not require treatment. Another category requires treatment, such as supraventricular tachycardia, including atrioventricular nodal reentrant tachycardia, which can be cured by radiofrequency ablation. Additionally, conditions like atrial fibrillation can be treated with radiofrequency ablation; many patients may be cured, but some may not respond to this treatment and require medication instead. There are also patients with intrinsic structural heart disease presenting various arrhythmias that can only be managed with medication, not cured.

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.

Does arrhythmia premature beat have danger?

Premature beats, also known as premature contractions, abbreviated as premature beats, are a type of early ectopic heartbeats. They can be classified according to their origin into sinus, atrial, junctional, and ventricular, with ventricular being the most common. Premature beats are a common type of ectopic rhythm that can occur on the basis of sinus or ectopic rhythms, such as atrial fibrillation. They can occur occasionally or frequently and may irregularly or regularly follow each or several normal beats, forming a bigeminy or trigeminy pattern of premature beats. Generally, sinus, atrial, and junctional premature beats do not involve rapid ventricular rates and are usually not life-threatening. Although most premature beats are functional and do not cause damage to the heart, some pathological premature beats occurring on the basis of structural heart disease may further induce arrhythmias. In particular, ventricular premature beats may provoke ventricular tachycardia or ventricular fibrillation and in severe cases, may lead to sudden cardiac death. Additionally, multifocal atrioventricular premature beats are often a precursor to atrial fibrillation.

What tests are done for arrhythmia?

Arrhythmia is also relatively common in clinical practice, and its common detection method is mainly the electrocardiogram (ECG). ECG is a simple and non-invasive operation that helps to identify the type of arrhythmia. Another method is the 24-hour Holter monitor, which can record all heart rate changes occurring within 24 hours. If an arrhythmia occurs, it is crucial to seek medical attention promptly, visiting a cardiology department. Treatment may involve antiarrhythmic medications, and if possible, a complete electrophysiological examination can be performed.

What department should one go to for arrhythmia?

Arrhythmia is an important group of diseases among cardiovascular diseases. It can occur on its own or in conjunction with other cardiovascular diseases, thus it mainly requires consulting a department of cardiology. However, due to other causes such as electrolyte or endocrine disorders, anesthesia, hypothermia, thoracic or cardiac surgery, drug effects, and central nervous system diseases, the assistance of endocrinologists and neurologists is needed for diagnosis and treatment. Sometimes, the arrhythmia might be caused by endocrine disorders, such as thyroid diseases or hypoglycemic symptoms in diabetes, necessitating a consultation with the department of endocrinology. If symptoms like transient blindness, fainting, dizziness, or convulsions occur, it is essential to consider brain-related diseases, such as epilepsy or transient insufficient brain blood supply, and consult the department of neurology to make a differential diagnosis.
