When physical examination, what condition is the heart appears 4 times premature beat

When physical examination, the heart appears four premature beats are caused by staying up late, heart failure, myocarditis and other reasons. The specific analysis is as follows:

1. Staying up late

if the patient stays up late for a long time, leading to sympathetic nervous system disorder, affecting cardiac nerves, causing cardiac dysfunction and premature beats.

2. Heart

failure patients due to heart deformation, cell remodeling, affecting normal heart conduction, the above phenomenon occurs.

3. Myocarditis

If the patient is seriously ill, leading to inflammatory reaction to stimulate heart cells, causing insufficient blood supply to the heart, causing premature heart contraction and premature beats.
