Myocarditis has what symptom and how to cause

Myocarditis is mostly caused by pathogen infection, physical and chemical factors, decreased immune function and other reasons. 1. Pathogen infected patients myocardial tissue by viruses, bacteria and other pathogens infection, inflammation continues to damage myocardial tissue, can cause myocarditis. 2. Physical and chemical factors If the patient long-term exposure to ionizing radiation or chemicals, can continue to damage myocardial cells, can induce myocarditis. 3. Immune function decreased If the body immunity is reduced, can increase the probability of myocarditis. Myocarditis can appear palpitations, chest distress, dyspnea and other symptoms. 1. Palpitations due to myocardial cell ischemia, myocardial cells can appear excessive contraction, causing palpitations. 2. Chest distress If the patient myocardial tissue necrosis, heart can not contract normally, blood stasis in the heart, can appear chest distress. 3. Dyspnea If the heart blood stasis is excessive, squeezing the lungs, lung ventilation function is reduced, can also appear dyspnea phenomenon.
