Voltage-gated T-type Ca2+ channels (T-channels) are normally expressed during embryonic development in ventricular myocytes but are undetectable in adult ventricular myocytes. Interestingly, T-channels are reexpressed in hypertrophied or failing hearts. It is unclear whether T-channels play a role in the pathogenesis of cardiomyopathy and what the mechanism might be.Here we show that the a1H voltage-gated T-type Ca2+ channel (Cav3.2) is involved...
