Junctional ectopic tachycardia evolving into complete heart block.
Transition from congenital junctional ectopic tachycardia to complete AV block was observed in an 8 month old girl, over a 36 hour period, during initial hospital admission. Two years later she had evidence of a rapidly increasing left ventricular end diastolic diameter, associated with lowest heart rates during sleep of < 30 beats/min. A transvenous permanent pacemaker was therefore implanted....
متن کاملSecond degree block during reciprocal atrioventricular nodal tachycardia.
Of 67 patients with reciprocal atrioventricular (A-V) nodal tachycardia consecutively studied by programmed electrical stimulation of the heart, nine patients showed second degree block toward the ventricle and one patient toward the atrium during tachycardia. In four patients the occurrence of block was critically related to the prematurity of the test stimulus initiating the tachycardia. In t...
متن کاملJunctional rhythm associated with ventriculoatrial block during slow pathway ablation in atypical atrioventricular nodal re-entrant tachycardia.
AIMS We assessed responses to slow pathway ablation with respect to the appearance of ventriculoatrial (VA) block during junctional rhythm in both typical and atypical types of atrioventricular nodal re-entrant tachycardia (AVNRT). METHODS AND RESULTS The 31 subjects included 16 patients with slow-fast type of typical AVNRT and 15 patients with atypical AVNRT (9 patients with fast-slow type a...
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...
