It is possible to distinguish lead reversal and [[w:Dextrocardia|dextrocardia]] by watching the precordial leads. Dextrocardia will show an R wave inversion, wheras lead reversal will not. | It is possible to distinguish lead reversal and [[w:Dextrocardia|dextrocardia]] by watching the precordial leads.
