Abstract

Passive electrical properties of SA node region of rabbit's heart were studied. Electrotonic anisotropism was characteristic of the entire SA node; anisotropism decreased moving from crista terminalis to interatrial septum. The input resistance, R(bx), was the largest in the region of true pacemakers and decreased moving to the perinodal region. Analysis of the results yielded specific resistance values for contacts and electrogenic membrane of 3 Ohms.cm2 and 104 Ohms.cm2 respectively.
