title: Recording undetected P waves in a case of heart transplant with a new bipolar system.
abstract: Using a new electrocardiographic lead (L-P lead), we recorded undetected P waves in a post heart-transplant patient. This case shows another application of a noninvasive method, a modification of Einthoven's bipolar leads, used to approach undetermined rhythms.
