Kv-current properties of atrial and ventricular FBs from CHF dogs. (A) Representative current recordings from FBs from a CHF dog at baseline (left) and after treatment with 30 mmol/L of TEA (right). (B) Baseline current–density voltage relationships (expressed as total end-pulse current) for CHF atrial and ventricular FBs. The voltage-clamp protocol (inset) was delivered at 0.1 Hz. (C) and (D) Comparison of TEA-sensitive current densities (baseline current densities minus current densities in 30 mmol/L of TEA) between control and CHF dogs for both atrial (AFB) and ventricular FBs (VFB). ***P < 0.001 for control vs. CHF FBs by two-way ANOVA. n/N, number of cells/number of dogs.
