Study design and in vivo electrophysiology. A Experimental protocol. B Echocardiographic parameters of the control (healthy rats; n = 7), experimental (rats with myocarditis; n = 9), and treatment (MCC950-treated rats with myocarditis; n = 8) groups. C ECG readings before and after myosin peptide injection; rats with myocarditis had abnormal ECG morphologies with QRS fragmentation. D Representative electrocardiographic tracings and average data of the control (n = 7), experimental (n = 7), and treatment (n = 7) groups on days 1 (baseline) and 21 (after treatment). E ECG tracing revealing spontaneous premature ventricular contractions in a rat with myocarditis. F ECG tracing indicating caffeine (120 mg/kg)-induced ventricular tachycardia in a rat with myocarditis. ECG, electrocardiography
