Ventricular action potential and L-type calcium channel in infarct-induced hypertrophy in rats.


INTRODUCTION The present investigation was aimed at characterization of: (1) action potential parameters; and (2) L-type calcium channels in the hypertrophied ventricular tissue surviving an extensive healed myocardial infarction in the rat. METHODS AND RESULTS Myocardial infarction was produced in Wistar rats by ligation of the left coronary artery. One… (More)
