To obtain the highest R/T ratio, for good
The R/T ratio increased as the angle of
lead II axis became further away from the body axis and as the apex
electrode and the apex of the heart became a little further apart than the
basic placement position.
The basic placement position was the
lowest in the order of R/T ratios among the five kinds of electrode positions
(p < 0.01).
