Myocarditis once a lifetime can not be good this statement is wrong, generally light myocarditis as long as attention to rest, follow the doctor’s instructions for symptomatic medication, generally can be recovered; severe myocarditis need long-term treatment. Mild myocarditis is characterized by weakness, followed by pallor, sweating, shortness of breath, palpitations (accelerated heartbeat, often accompanied by panic), dizziness, chest tightness, mental instability, etc. It is self-limiting, and it is important to pay attention to adequate rest, and medication is mainly used to alleviate the symptoms of cardiac arrhythmia and cardiac insufficiency. Severe type is less common, the onset of the disease is faster, the disease progresses rapidly, usually within 1~2 days can appear heart failure symptoms, or soon appear shock. There is often severe fatigue and weakness, emotional irritability, dizziness, vomiting, and pressure-like pain in the precordial region, which may be life-threatening if not rescued in time. Patients should pay attention to rest during the onset of the disease, patients need to monitor blood pressure and temperature in real time, patients should avoid exertion and supplement nutrients. Myocarditis must be timely to the hospital, under the guidance of the doctor’s active treatment, so as not to delay the condition.
