In 9 patients with various forms of heart rhythms and rates, all of whom had a temporary pacemaker electrode inserted, several single premature ventricular contractions (PVC) with various coupling intervals (CI) were induced. The relative systolic area of the carotid pulse curve in the postextrasystolic beat was used as an indicator of the degree of postextrasystolic potentiation (PESP). A close correlation between PESP and CI was found only in sinus rhythm patients (r = -0.85). The patients with junctional and ventricular rhythms had no PESP regardless of CI or the degree of heart failure. Compensatory pause (CP) in these patients surprisingly related (r = 0.95) to heart rate, slower rates having a shorter relative CP.

It is reported in two cases of synostosis of the vertebral which is related in the Medical literature as "Dysontogenetic blockbuilding of the Corpus Vertebrae". This condition could be seen in a 13 year old boy in the area of Th 9 to Th 12 and in a 13 year old girl from Th 11 to L1. The clinical and radiological findings of these two cases will be described and discussed. An attribution of these cases to the "Dysontogenetic blockbuilding" groups was based on a disturbance of the vertebral forming. A causal therapy is not possible.
