Valproic acid (VPA) delays the onset of atrial fibrillation (AF) in CREM-IbΔC-X transgenic (TG) mice. A Representative ECG traces of a wild-type (WT) mouse in sinus rhythm (left) and a transgenic mouse showing AF (right). B, AF increased with age in TGVEH as demonstrated by Kaplan-Meier plots showing the survival of mice with AF. VPA treatment delayed the onset of spontaneous AF in TGVPA mice. No AF was observed in WT animals (n=19–20 [WT]; 32–36 [transgenic] animals/group). *P<0.05 vs WT;P<0.05 vs vehicle (VEH). CREM-IbΔC-X indicates CREM (cAMP responsive element modulator) isoform IbΔC-X.
