Abstract
⺠NE induces spontaneous activity in isolated PV cardiomyocytes. ⺠Morphological and electrophysiological properties differ between PV and LA myocytes. ⺠Both a1 and b1-receptor stimulations are required for NE-induced automaticity. ⺠Release of Ca2 + via IP3R activates NCX to cause automaticity. ⺠T-tubule system is enriched in PV cardiomyocytes, in contrast to atrial cells.
