Patient Male, 29 years old, clinical diagnosis: Viral myocarditis. Electrocardiogram (with photo) shows sinus arrhythmia with a PP interval of 0.85-0.99 seconds, a sinusoidal downtime PR interval of 0.12 seconds, and a normal QRS morphology. Frequency of premature beats: 1, borderline: QRS wave morphology and sinus was slightly different Rs, such as the B line R_4, E line R_2, R_3, R_6, time limit of 0.08 seconds, before and after no correlation P wave, Echocardiographic pairing interval ranging (0.74-0.88 seconds), a continuous premature beat interval (E line
