Had ecg and blood work 2 days into virsl illness.now heart racing and skipping lots. 3 days later is myocarditis still possible?

Relax ;): Myocarditis is an unusual presentation of a viral illness. For arrythmias, skipped beats to be a presentation of myocarditis is possible, you would most likely be far sicker than you are with a depressed cardiac function, and feeling very fatigued. Having occasional PVC (Premature Ventricular contraction) during viral infections is a relatively common picture. Relax ;)
