Introduction

In general, first-degree atrioventricular block refers to first-degree atrioventricular conduction block, which can be reversible. First-degree atrioventricular block, also known as first-degree atrioventricular conduction delay, is defined as a prolongation of the atrioventricular conduction time beyond the normal range, yet every atrial impulse is still conducted to the ventricles. It is a diagnostic term used in electrocardiography.

In general, first-degree atrioventricular block refers to first-degree atrioventricular conduction block, which may be reversible.

First-degree atrioventricular conduction block means prolonged atrioventricular conduction time exceeding the normal range, but every atrial impulse can still be conducted to the ventricles. It is also known as atrioventricular conduction delay. This is an electrocardiographic diagnostic term characterized specifically by a prolonged PR interval on the ECG—typically greater than 0.20 seconds—with each P wave followed by a QRS complex. If no significant symptoms are present, or if the condition is caused by reversible factors such as increased vagal tone, medication side effects, or electrolyte imbalances, appropriate and timely treatment may lead to recovery or improvement. In such cases, the condition usually does not cause significant harm to the body, especially in patients with good physical fitness and healthy lifestyles including regular aerobic exercise, and often requires no specific treatment. However, when first-degree atrioventricular block is associated with severe arrhythmias, myocarditis, or other conditions involving irreversible degenerative changes in the atrioventricular conduction system, spontaneous recovery is unlikely.

A frequent, small-meal eating pattern is recommended to reduce gastrointestinal burden and prevent discomfort caused by overeating.

Will my voice return to normal after a cold causes hoarseness?

In general, whether hoarseness caused by a cold can recover depends on the specific situation. Hoarseness due to mild mucosal congestion usually resolves completely; however, if the vocal cords suffer severe damage or pathological changes, recovery becomes more difficult. Daily care should include adequate vocal rest, avoiding loud talking or singing. Drinking plenty of warm water helps keep the throat moist, while spicy or excessively hot foods should be avoided to prevent irritation.

Does whooping cough still require medication if there is still an occasional cough at night?

If pertussis has entered the recovery phase, and the patient has completed a full course of standardized treatment, with daytime coughing nearly resolved and only occasional mild coughing at night—without other symptoms such as fever, shortness of breath, or vomiting—medication may generally be discontinued after medical evaluation. At this stage, the mild cough is usually a normal response during the healing process of the respiratory mucosa, and the body can gradually recover on its own without continued reliance on medication.

Can people with bronchitis and cough eat eggs?

In general, patients with tracheitis and cough can usually consume eggs if they are not allergic to them; however, those with a history of egg allergy must absolutely avoid eggs. During tracheitis with cough, the diet should be light and nutritionally balanced, and drinking plenty of warm water helps keep the throat moist. It is also important to ensure indoor ventilation, avoid exposure to irritants such as dust and smoke, reduce coughing episodes, and promote recovery.

Can mild pulmonary hypertension be cured?

In general, whether mild pulmonary hypertension can be cured depends on whether the underlying cause is clear and removable. Cases secondary to left heart disease or lung diseases often improve once the underlying cause is addressed; however, idiopathic pulmonary hypertension is difficult to cure completely and requires long-term management. Patients with mild pulmonary hypertension should avoid smoking and excessive alcohol consumption, refrain from strenuous exercise and high-altitude environments, and reduce stress on the lungs in daily life.

Can a patient with a lung perforation drink duck soup?

Patients with lung perforation can drink duck soup in moderation. Duck soup is nutritious and easy to digest, providing high-quality protein and hydration that support bodily recovery, but specific consumption guidelines should be followed. If discomfort such as worsened cough, chest tightness, or shortness of breath occurs after drinking, consumption should be stopped immediately and medical attention sought promptly. The amino acid composition of its high-quality protein is close to that of the human body.

Does whooping cough still cause coughing at night during the recovery phase?

If in the early recovery phase of pertussis, where severe coughing symptoms have only recently subsided and the respiratory mucosa is still healing, occasional mild coughing—perhaps just one or two episodes at night—may occur. This type of cough is usually irregular, not accompanied by shortness of breath, vomiting, or other discomforts, and its frequency gradually decreases as recovery progresses. It represents a normal part of the body's healing process.

What medication is effective for bronchitis to recover quickly?

Bronchitis requires targeted use of anti-infective agents, cough suppressants, expectorants, anti-asthmatic drugs, and anti-inflammatory medications based on the underlying cause. Appropriate medication can accelerate recovery and prevent worsening of the condition due to inappropriate drug use. If symptoms persist for more than one week or are accompanied by high fever or difficulty breathing, prompt medical evaluation is recommended to determine the cause. In cases caused by bacterial infection, cephalosporins or penicillins may be used.

How long until shortness of breath and coughing when speaking get better?

Recovery from shortness of breath and coughing during speech typically takes 1–2 weeks. If symptoms persist beyond 2 weeks or worsen, prompt medical evaluation is necessary to rule out organic diseases such as pneumonia or asthma. These symptoms are often triggered by respiratory tract infections, with congestion and swelling of the airway mucosa leading to impaired ventilation; the type of infection is a key influencing factor.
