Quantitative evaluation of postectopic beats in the normal and failing human heart using indices derived from catheter-tip manometer readings.
Postextrasystolic potentiation was studied by means of a catheter-tip manometer in patients with and without cardiomyopathy. The results imply that the enhancement of the left ventricular contraction is increased in patients with cardiomyopathy.
