which is the length-average cross-correlation or similarity of the excitation wave and a wave that would propagate on the line.
From the early activation area on the epicardium of PV sleeves, the excitation wave spreads to the left atrial appendage and interatrial septum, and meets with the depolarization front, moving from the right atrium.
Methods: The excitation wave spreading along epicardium in the area of pulmonary veins ostia in the left atrium at 36-37[degrees]C and when cooling to 32[degrees]C was studied by the method of electrocardiochronotopography in rabbit of Chinchilla species, five months age.
