Many people do not understand, the cold is obviously the problem of the respiratory tract, why the heart of the infringement? This is because the child's immune function is not perfect enough, vulnerable to various bacteria, viruses invade the myocarditis after a cold may be a direct invasion of influenza virus May also be caused by the autoimmune response induced by virus infection caused by this myocarditis occurred in early childhood, followed by adolescence, the younger, the more serious the disease, the higher the mortality rate over the past decade, both at home and abroad The incidence was significantly higher.

Coupled with the unclear expression of the child, it is easily overlooked by parents until the child is experiencing dyspnea, palpitations, Convulsions, many parents just aware .However, parents from the following aspects to speculate whether the child's colds caused myocarditis.First, check the color.As the virus affects the heart and affect the heart function, the human body will be hypoxia.Although the child was ablated , The face is still gray, blue lips cyanosis.Second is to observe the state of mind.Usually good children, after a cold sluggish, fat, always shout dizzy boring, move about wheezing, chest tightness, palpitation, but also the performance of heart damage The third is to observe the pulse.Quiet or sleep, the child pulse less than 60 times per minute or more than 120 times, or after a few jumps appear longer gap, are not normal.
Viral myocarditis lesions can be summarized as 'one of the three', that is, 'a big, a small, fast'.

Less' refers to less clinical symptoms, many children have no symptoms. 'Fast' is the rapid changes in condition, a short period of time to expand the heart diffuse, heart failure; some arrhythmia, repeated fainting, and even sudden death.
Children often can not accurately express their own condition, parents must be careful observation, especially after the flu grow, lazy move, sweating children, it is best to take the hospital to do the necessary checks, such as myocardial enzymes, cardiac troponin , Electrocardiogram, etc ..
