This invention relates to thieno tetrahydropyridine and isoquinoline derivative compounds which are useful as antiarrhythmic agents, pharmaceutical compositions comprising such compounds, novel intermediates for their preparation and their methods of use. More particularly these thieno tetrahydropyridine and isoquinoline derivative compounds have been demonstrated to increase the effective refractory period (ERP) of isolated perfused cardiac tissue in vitro.
