Children are multiple, easy to occur in winter and spring, droplets and play utensils and clothes spread and invade the respiratory tract such as tonsil, throat and other respiratory tract complicated with myocarditis, while showing respiratory tract and heart, circulatory system, digestive system and systemic symptoms, causing cardiogenic shock, and so on. are the characteristics of diphtheria myocarditis. In addition, there are rapid onset and development, necrosis and scar in the focal area, leading to cardiac conduction system degeneration, congestive heart failure and so on.

Specifically, from the classification of diphtheria, there are nasal diphtheria, pharyngeal diphtheria, diphtheria, other parts of diphtheria, etc., from the incidence and symptoms, children and other groups infected with Corynebacterium diphtheriae, after 1-7 days incubation period, there will be fever, nausea, vomiting, and pharynx and other parts of the formation of diphtheria pseudomembrane, and mucosal necrosis, local lymph node enlargement and respiratory tract obstruction, inhaling cicada sounds or three concave signs.

When diphtheria causes circulatory involvement and shows systemic symptoms, it indicates that myocarditis has been developed. Such as pallor, weakness, dyspnea, cyanosis and other symptoms. At this time, the examination can find that the heart is slightly or moderately enlarged, the heart sound is low and dull like a fetus, and most of them will have atrioventricular block, bradycardia or tachycardia, and there will be a wind-like murmur and diastolic rhythm in the precordial area.

When there is extensive cardiomyopathy in the development of diphtheria myocarditis, cardiogenic shock will occur, and it will occur two or three weeks after the onset, and there will be symptoms such as nausea, vomiting, pale skin, abdominal pain and so on. then there may be cold limbs, weak pulse, decreased blood pressure, shock and other causes of shock, as well as the toxin produced by Corynebacterium diphtheria, which will be toxic to the surrounding small blood vessels and vasomotor centers. Lead to pulmonary congestion, systemic blood stasis, congestive heart failure, promote the occurrence of shock.
