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.

How to relieve arrhythmia

The relief of arrhythmia mainly involves removing any triggers if they exist, as well as using non-pharmacological methods, including ocular compression, carotid sinus massage, pinching the nose and forcefully exhaling, and breath-holding, which are methods to reflexively stimulate the vagus nerve. If relief is unachievable and the episodes are accompanied by hypotension, fainting or near-fainting, seizures, angina, or heart failure, it is crucial to seek medical attention promptly for pharmacological interventions against arrhythmias, or even consider electrical treatments such as cardioversion, defibrillation, pacemaker implantation, and ablation, as well as surgical options.

What is ventricular arrhythmia?

Ventricular arrhythmias mainly refer to disorders of the ventricular rhythm and are relatively common clinically, including premature ventricular contractions, ventricular tachycardia, ventricular flutter, and ventricular fibrillation. Premature ventricular contractions generally do not cause noticeable clinical symptoms, while ventricular flutter and ventricular fibrillation are very dangerous clinically and must be treated promptly with defibrillation. Therefore, ventricular arrhythmias must be treated promptly, actively treating the underlying disease, and managing the arrhythmia to prevent sudden death.

Do arrhythmias need treatment?

The treatment of arrhythmias should be based on the symptoms of the patient, the type of arrhythmia, and its impact on hemodynamics to determine if treatment is necessary. For instance, mild sinus bradycardia, irregular sinus rhythm, occasional atrial premature contractions, and first-degree atrioventricular block have minimal impact on hemodynamics. Therefore, if there are no obvious clinical symptoms and no cardiac structural disease, temporary drug treatment may not be required. However, severe arrhythmias such as sick sinus syndrome, rapid atrial fibrillation, paroxysmal supraventricular tachycardia, and persistent ventricular tachycardia can cause palpitations, chest tightness, dizziness, low blood pressure, severe sweating, and in severe cases, syncope, Adams-Stokes syndrome, or even sudden death, which require immediate medical attention.

Can arrhythmia cause sudden death?

The clinical manifestations of hemodynamic changes caused by arrhythmias mainly depend on the nature, type, cardiac function, and the extent of impact on hemodynamics. Mild conditions such as slight sinus bradycardia, sinus arrhythmia, occasional atrial premature contractions, and first-degree atrioventricular block have minimal impact on hemodynamics and therefore do not exhibit significant clinical manifestations, and sudden death is generally not expected. However, more severe arrhythmias, such as sick sinus syndrome, rapid atrial fibrillation, paroxysmal supraventricular tachycardia, and sustained ventricular tachycardia, can lead to palpitations, chest tightness, dizziness, hypotension, and sweating. In severe cases, syncope, Adams-Stokes syndrome, or even sudden death may occur.

Can people with arrhythmia take Jiuxin Pills?

Arrhythmias are an important group of cardiovascular diseases. They can occur alone or in conjunction with other cardiovascular diseases. Mild arrhythmias that do not affect hemodynamics often show no clinical symptoms. Arrhythmias can cause a reduction in coronary artery blood flow. Although various arrhythmias can decrease coronary blood flow, they rarely cause myocardial ischemia. However, in patients with coronary heart disease, various arrhythmias can induce or exacerbate myocardial ischemia, primarily manifested as angina and shortness of breath. The function of Jiu Xin Wan is mainly to promote Qi circulation and blood flow, remove blood stasis, relieve pain, increase coronary blood flow, and alleviate angina. Therefore, it is acceptable to take Jiu Xin Wan for arrhythmias combined with myocardial ischemia, but it is not recommended for those without clinical symptoms.
