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.

Arrhythmia is what?

Arrhythmia refers to abnormalities in the frequency, rhythm, origin, or conduction of the heartbeats. It can occur in healthy individuals as well as those with related diseases, and may involve cardiac diseases or other medical conditions. The primary mechanism behind the occurrence of arrhythmias is the abnormal formation of cardiac impulses or the abnormal conduction of these impulses. It is important to actively seek the causes of arrhythmias and control the factors that trigger them. For diseases associated with arrhythmias, proactive management is necessary. When severe arrhythmias occur, timely and effective treatment is crucial to prevent adverse outcomes.

Causes of arrhythmia

There are many causes of arrhythmia, which can be physiological or pathological. Pathological causes can originate from the heart itself or from other diseases. For instance, normal individuals might experience sinus arrhythmia, and circumstances such as staying up late, emotional excitement, or excessive fatigue can lead to premature beats or sinus tachycardia, among others. Other diseases, such as hyperthyroidism or fever, can cause an increased heart rate. For example, pulmonary embolism can lead to atrial fibrillation. Heart-related diseases, like heart failure, can cause ventricular premature beats, and diseases of the sinoatrial node itself can lead to sick sinus syndrome, among others.

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.
