(1) This report serves to highlight neonatal lupus erythematosus as a cause of neonatal congenital
complete heart block in babies born of yet asymptomatic mothers.
The tissue damage that causes
complete heart block is most usual in elderly people and is closely linked to coronary artery disease, for which lifestyle factors, such as smoking, increase the risk.
In a study of twenty-three patients with moderate to severe OSA who were each implanted with an insertable loop recorder, about 50% were observed to have frequent episodes of bradycardia and long pauses (
complete heart block or sinus arrest) during sleep (9).
In case 2, the fibrosis and calcification of the atrioventricular node likely resulted in
complete heart block and, ultimately, the patient's death.
Third-degree AV block or
complete heart block is present when impulses from the atrium are not conducted to the ventricles (Figure 4E).
During about 4 years of follow-up, cardiovascular diseases were diagnosed in 12 patients (7%), including cases of coronary artery disease,
complete heart block, drug-refractory atrial fibrillation, and valvular dysfunction.
Alice Brown, a mother of two from Oriel Drive in Aintree, needed a pacemaker after being diagnosed as having a
complete heart block at Fazakerley hospital.
Doctors diagnosed that she had a
complete heart block and said a pacemaker needed to be fitted.
He had an unstable course complicated by a
complete heart block requiring pacemaker insertion and returned to the operating room for excessive mitral regurgitation when a stitch in the repair dehised.
In patients with
complete heart block, physiological pacing improves a number of haemodynamic parameters.
Complete heart block has been reported in 0.23-6.4% in several studies17-20,24,30 which usually occurs immediately after the procedure due to device oversizing, squeezing effect of the device, direct compression or can present late due to fibrous tissue formation secondary to inflammation19,31.
