In SA node and AV node, how is ERP - effective refractory period defined and how does it change with sym or psymp activation?
Like its pretty clear in purkinje cells but what about these slow fibre? Considering that calcium channel transitions are time depepndent does it include phase4 (or a part of it) in ERP?
