A method of placing a pacing lead in the heart includes moving an electrode catheter successively to a plurality of possible placement sites. The viability of the tissue at each site is determined. If the tissue at the site is viable, a pacing signal is applied to the tissue at the site, and the effectiveness of the pacing from the site is measured. After the area has been mapped in this fashion, at least one pacing lead is placed from at least one of the sites which exceeded a predetermined level of pacing effectiveness.
