[Experimental evaluation of the critical size of the myocardial reverberator].
Two independent experimental methods for estimating the minimal size of myocardium where a rotating wave could still arise (the crucial wave size) were proposed and realized. The first one was based on measuring the wavelength, the second--on the determination of the crucial size of an unexcited obstacle. The crucial rotating wave size in the myocardium without an obstacle was shown to increase under lidocaine effect.
