It was found that exposure to isoptin reduced the amplitude of action potentials by 15.8 mV (41.19%), the pre-potential value by 11.5 mV (68.6%); prolongs the phase of slow diastolic depolarization by 176.5 ms (54.5%), the phase of systolic depolarization by 20.12 ms (29.1%); shortens repolarization by 34.5 ms (17.5%) and slows the frequency of spontaneous activity by 22.0 per 1 min (18.4%).
