ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the possibility of resultant cardiac vector of ex vivo guinea pig heart.</p><p><b>METHODS</b>ECGs were recorded in 4 directions on every plane, and in each direction 4 points at different distances from the anterior, posterior, right and left of isolated guinea pig ventricles immersed in normal saline and distilled water.</p><p><b>RESULTS</b>Main upward waves of ECGs were recorded at all points in 4 directions at 3 levels in the two media. The voltage distribution of normal electrocardial field of the QRS wave was of all-round outward shape, which did not match the resultant cardiac vectors between the left and right and between the anterior and posterior ventricular walls.</p><p><b>CONCLUSION</b>There are some confusion and contradiction in the resultant cardiac vector based on the voltage distribution of electrocardial field around ex vivo guinea pig heart.</p>
