Résumé

Acute stimulation of the late sodium current (I We aimed to investigate whether the increase of the systolic Ca We used a transgenic mouse model in which PKARIα was made resistant to oxidative activation by homozygous knock-in replacement of redox-sensitive Cysteine 17 with Serine within the regulatory subunits of PKARIα (KI). ATX-II (at 1 nmol/L) was used to acutely enhance I ATX-II increased I The inotropic and arrhythmogenic effects of acutely increased I
