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.

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.

What should be paid attention to in daily life with arrhythmia?

For managing arrhythmias, it's important to pay attention to several aspects. First, maintain a regular lifestyle and ensure adequate sleep. Second, the living environment should be quiet and serene to avoid noise, and it’s beneficial to grow various plants for a better temperament. Third, balance work and rest according to personal capacities and engage in appropriate physical activities such as walking, Tai Chi, and Qigong; moderate sexual activities and avoid colds. Fourth, strive to maintain a standard weight and not indulge in overeating, as obesity can increase cardiac load. Fifth, be mindful of changes in seasons, weather, and climate, as extreme cold or hot conditions can significantly impact the disease, potentially aggravating or triggering arrhythmias. Sixth, diet should be light with frequent, small meals, and avoid coffee, strong alcohol, fried foods, and minimise strong tea. Seventh, keep a stable emotional state and try to eliminate stress, fear, anxiety, irritation, and anger which are stimulants that could negatively affect your emotions. Eighth, in addition to daily medications, have emergency medications prescribed by a doctor on hand, such as Xintiandan, Shexiang Baoxin Pill, Xintongding, Atropine, etc. Ninth, if there are sudden exacerbations of arrhythmia accompanied by palpitations, chest tightness, dizziness, low blood pressure, and sweating, and in severe cases fainting, seek medical attention promptly.

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.

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.
