obtained using a standard trypsin-collagenase
digestion protocol - myocytes were plated on 25 mm glass coverslips
and used within 3-5 days after plating - cells were loaded with the calcium-sensitive
indicator Fluo-4 (Kd345 nM) and wave propagation
was visualized by following calcium transients - the events were monitored at room temperature
using ether a Zeiss LSM 510 confocal imaging
