Summary
1.
A patient with a short P-R interval and a prolonged QRS complex, and no other evidence of cardiovascular disease, died in an attack of paroxysmal tachycardia.
2.Gross examination of the heart showed no evidence of disease.
3Serial histologic sections of a portion of the auriculoventricular groove showed three muscular connections at the right lateral border of the heart between the right auricle and right ventricle. Two of these bridged a small part of the ventricular cavity during their course.
4The demonstration of the presence of these structures, which should be capable of conducting an impulse from auricle to ventricle, furnishes further support for the hypothesis of an accessory pathway of auriculoventricular conduction as an explanation for this electrocardiographic anomaly.
