Introduction

In general, cardiac premature beats refer to premature contractions. Premature contractions accompanied by mild coughing may be caused by factors such as excessive fatigue, emotional fluctuations, bronchitis, hyperthyroidism, or pulmonary arterial hypertension. Treatment options include general management and medication, under a doctor's guidance. If symptoms persist, timely medical consultation and relevant examinations are recommended.

Generally speaking, cardiac premature beats refer to premature contractions. Premature contractions accompanied by mild cough may be caused by excessive fatigue, emotional fluctuations, bronchitis, hyperthyroidism, pulmonary hypertension, and other factors. Treatment options include general therapy and medication under a doctor's guidance. If discomfort occurs, timely medical consultation and related examinations are recommended. Detailed analysis is as follows:

1. Excessive Fatigue

When the body remains in a state of high-intensity work or sleep deprivation for a prolonged period, the excitability of the sympathetic nervous system increases, leading to abnormal cardiac rhythm and premature contractions. Additionally, excessive fatigue may cause dryness and increased sensitivity of the throat mucosa, resulting in mild coughing. In daily life, sufficient rest should be ensured, staying up late avoided, and a proper balance between work and rest maintained.

2. Emotional Fluctuations

Emotional fluctuations can elevate catecholamine levels in the body, stimulating the electrical activity of myocardial cells and causing premature contractions. Moreover, emotional changes may affect the respiratory center, altering breathing patterns and triggering mild coughing. It is recommended to maintain a good mental state, relieve stress through meditation or deep breathing, and avoid excessive mental stimulation.

3. Bronchitis

Bronchitis is mainly caused by bacterial or viral infections. Inflammation of the bronchial mucosa may enhance the cough reflex, while inflammatory factors might affect cardiac rhythm, leading to premature contractions. Accompanying symptoms include sore throat, sputum production, and fever. Patients may take medications such as amoxicillin capsules, cefixime tablets, and acetylcysteine granules as directed by a physician, and should ensure adequate rest and hydration.

4. Hyperthyroidism

Excessive secretion of thyroid hormones accelerates metabolism, causing tachycardia and arrhythmias, and may also lead to dryness of the respiratory tract, resulting in mild cough. Accompanying symptoms include hand tremors, heat intolerance, and weight loss. Patients may take medications such as methimazole tablets, propylthiouracil tablets, and levothyroxine sodium tablets under medical guidance, with regular monitoring of thyroid function.

5. Pulmonary Hypertension

Pulmonary hypertension may be caused by environmental factors, medications, heart disease, pulmonary diseases, and other reasons. Due to increased pulmonary vascular resistance and increased burden on the right ventricle, premature contractions may occur, while pulmonary hypoxia may cause mild coughing. Symptoms may include chest tightness, shortness of breath, and cyanosis of the lips. Patients may take medications such as bosentan tablets, ambrisentan tablets, and tadalafil tablets as directed by a physician.

In daily life, maintain regular作息, avoid staying up late, ensure sufficient sleep, and reduce or avoid exposure to cold air, irritant gases, strong tea, coffee, and alcohol.

Are heart palpitations a sign of myocarditis?

Premature contractions are not the same as myocarditis. Premature contractions refer to irregular heartbeats that may represent normal physiological phenomena but could also be associated with organic heart disease. Myocarditis, on the other hand, is usually related to viral infections. These two conditions are distinct; however, severe myocarditis may trigger premature contractions, leading to irregular heartbeats.

Can a cold cause premature heartbeats?

Whether a cold causes premature contractions mainly depends on the type and severity of the cold. Non-viral colds or mild colds usually do not cause premature contractions, whereas viral or severe colds may induce viral myocarditis, thereby leading to premature contractions and associated symptoms. Therefore, it is important to promptly identify the cause of the cold and provide targeted treatment accordingly.

Can ventricular premature beats in trigeminy rhythm return to normal?

Whether premature contractions can be restored mainly depends on the underlying cause. If caused by physiological factors, they may return to a normal state after improving lifestyle habits and generally do not require special treatment. However, premature contractions caused by pathological factors such as cardiomyopathy or coronary heart disease, especially in severe cases, are usually difficult to reverse and require treatment of the underlying disease or catheter radiofrequency ablation.

Which acupoint should be scraped for cardiac premature beats?

In general, cardiac premature beats refer to premature contractions. For premature contractions, acupoints such as Neiguan (PC6), Shenmen (HT7), Shanzhong (CV17), Xinshu (BL15), and Jueyinshu (PC8) can be stimulated. Normally, one should avoid intense emotional fluctuations and reduce stimulation from negative emotions such as tension, anxiety, and anger. Relaxation methods such as listening to music or meditation may help alleviate these emotions and prevent emotional factors from triggering premature contractions.
