Familial Atrioventricular Heart Block
A family of 28 individuals spanning four generations was investigated because of a finding of complete heart block in five members and the existence of a low degree of atrioventricular (A-V) heart block in a sixth member. The disorder was characterized by 1) adult onset in all, 2) complete A-V heart block in five and first degree A-V heart block in one, 3) sinus bradycardia in three, 4) atrial ...
متن کاملFetal atrioventricular heart block.
As part of routine prenatal care, the obstetrician of a 25-year-old gravida 1, para 0 woman performed fetal heart-rate monitoring at 22 weeks gestational age.

to the editor: The report by Toff and colleagues on the United Kingdom Pacing and Cardiovascular Events (UKPACE) trial (July 14 issue), 1 evaluating cardiovascular end points in elderly patients with atrioventricular block, showed that the use of dual-chamber pacing to maintain atrioventricular synchrony conferred no survival advantage over the use of single-chamber pacing. These results may be...
متن کاملMultilevel atrioventricular block.
Arrhythmias displaying conduction disturbances consistent with block at more than one level within the atrioventricular conduction system were seen in 36 patients during a two year period in a community hospital. Two levels of block were postulated in each patient; one patient also demonstrated a third level of block. In 24 patients (Type A), there was an integral conduction ratio at the upper ...
متن کاملSecond-degree atrioventricular block.
1) While it is possible only one type of second-degree AV block exists electrophysiologically, the available data do not justify such a conclusion and it would seem more appropriate to remain a "splitter," and advocate separation and definition of multiple mechanisms, than to be a "lumper," and embrace a unitary concept. 2) The clinical classification of type I and type II AV block, based on pr...
