[Wave-like spontaneous contractions of isolated cardiomyocytes].
Spontaneous wave-like contractions in single isolated rat cardiomyocytes are investigated by means of microcinematography and frame-by-frame analysis. Some basic wave patterns are described, as well as the effects of both solution components and preceding electrical stimulation. The typical wave velocity is found to be about 160 micron/s. Possible interrelation between the wave frequency and propagation velocity is discussed.
