Symptoms of viral myocarditis, teach you how to judge

Many diseases have similar symptoms, and misdiagnosis can cause great hidden dangers, especially for more serious diseases. If viral myocarditis is not treated promptly, it can cause serious complications. Therefore, misdiagnosis is unacceptable. Even if you are not a doctor, you can make a rough judgment based on some superficial body phenomena.

1. The illness can be mild or severe. The symptoms of viral myocarditis vary greatly in severity. Milder viral myocarditis may be asymptomatic, or present with symptoms of palpitations, chest tightness, and chest pain. It may also present with respiratory symptoms such as colds and coughs, or intestinal symptoms such as abdominal pain and diarrhea. Symptoms of severe viral myocarditis include: severe arrhythmias, heart failure, patients are prone to fatigue, decreased strength, shortness of breath, difficulty breathing, and even limited mobility. If the myocardial conduction system is invaded, it will cause arrhythmias and sudden death.

2. Some patients with viral myocarditis seek medical treatment with a prominent symptom that is related or unrelated to the heart as the main or initial symptom. like

① Patients who present with arrhythmia as the main complaint or first symptom are often seen.

② A small number of patients present sudden and severe chest pain as the main complaint, while systemic symptoms are very mild. This situation is more common in patients with viral myocarditis involving the pericardium or pleura.

③ A small number of patients seek medical treatment mainly with symptoms of acute or severe heart failure.

④ A very small number of patients seek medical treatment with severe systemic symptoms such as body pain, fever, oliguria, and syncope, but without obvious cardiac symptoms.

3. Physical signs

1. Changes in heart rate may be either an increase in heart rate that is disproportionate to the increase in body temperature, or a slow heart rate.

2. Arrhythmia rhythm is often irregular, premature beats are the most common, and they may become atrial or ventricular premature beats. Other bradyarrhythmias: atrioventricular block and sick sinus syndrome may also occur.

3. In mild cases of cardiac enlargement, the heart does not enlarge. Generally, there may be temporary enlargement which can be recovered.

4. Heart sounds and heart murmurs: The first heart sound in the apical area may be reduced or split, or may appear as a fetal heart sound. When pericarditis occurs, a pericardial friction sound occurs. A systolic blowing murmur may be heard at the apex. This is caused by fever and enlarged heart chambers; a diastolic murmur may also be heard at the apex, which is also caused by enlarged ventricular chambers and relative mitral stenosis.

5. Signs of heart failure In more severe cases, signs of left-sided or right-sided heart failure may appear, and even a series of signs of cardiogenic shock may occur in rare cases.
