[Reflex transient atrioventricular block during atrial fibrillation ablation].
148 A 55-year-old woman with a 5-year history of episodes of isolated atrial fibrillation (AF), refractory to various antiarrhythmic drugs, underwent a procedure to isolate the pulmonary veins. The 4 veins were mapped while brief episodes of AF were produced, and the suspected arrhythmogenic source was identified in the left superior pulmonary vein (LSPV). Figure 1 shows the recording in echoca...
متن کاملFamilial 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. The fetal heart rate was 90 bpm, below the expected range of 120 –160 bpm. This finding prompted a subsequent fetal ultrasound and echocardiogram. The ultrasound exam showed no evidence of hydrops. Cardiac anatomy was normal, with 4 appro...
متن کاملPacing for atrioventricular block.
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 ...
