[Increased atrial refractoriness: an explanation for the rarity of atrial arrhythmias in chronic cor pulmonale (author's transl)].

Right atrial monophasic action potential was recorded using a suction electrode catheter in 20 patients with chronic cor pulmonale. The duration of right atrial monophasic action potential was recorded using suction electrode catheter in 20 patients with chronic corpulmonale. The duration of right atrial monophasic action potential was 397 +/- 17 msec, longer than the normal value of 325 +/- 37 msec found in 30 normal subjects. The conclusion of our work is that the long right atrial monophasic action potential duration may explain the sinus rhythm stability and the rarity of atrial arrhythmias in chronic cor pulmonale.

Precordial electrocardiographic mapping technique.

Using an original device, unipolar electrograms in 36 points on the anterior thoracic wall were recorded. The equal intensity contour lines of the amplitudes of electrical events were drawn as precordial maps, by mathematical procedures.
