A patient with mumps myocarditis is reported. The onset of mumps was typical, with fever and parotid swelling followed by raised virus antibody titres. Atrioventricular block occurred and persisted despite steroid treatment for two weeks. He had an Adams-Stokes attack. A permanent pacemaker was implanted and, thereafter, the patient remained dependent upon it. The published material on conducti...

Ellis-van Creveld syndrome is transmitted as an autosomal recessive trait. This syndrome is accompanied in 60% of cases with congenital heart disease, mostly single atrium or large ASD. Patients are mostly symptomatic, but in this rare case despite 68 years of age, the patient was free of symptoms except for complete heart block for which pacemaker was inserted

Congestive heart failure in complete heart block may be promptly relieved by pacing, particularly in the elderly patient with heart block due to isolated disease of the conducting system, as the working myocardium is generally normal and effective control of the heart rate will promptly relieve dyspnoea and oedema, restoring the patient to normal activities by control of the heart rate alone. A...

Cardiac resynchronization therapy (CRT) has been proven its value in adult patients with congestive heart failure of low ejection fraction and wide QRS duration. Contrast to adult patients, CRT has been rarely applied for young patients. We report on a 9-yr-old boy with progressive left ventricular (LV) dilatation and dysfunction following chronic VVI pacemaker therapy for congenital complete a...

We describe a case of a preterm newborn with congenital complete atrioventricular block (CAVB), delivered for distress by cesarean section, and undergone, at 1295 grams of weight, to permanent pacemaker implantation. The pacemaker has been inserted between the upper left rectus abdominal muscle and the posterior rectus sheath and connected by two epicardial leads on the left ventricle wall. The...

We report a case of complete heart block in a patient with rheumatoid arthritis because of its rarity and unusual features like younger age, short duration and negative rheumatoid factor.

Complete heart block (CHB) is a potentially fatal condition occurring in approximately 1:10000 fetuses. Whilst it is well recognised that maternal anti-Ro and La antibodies are associated with fetal CHB, there are multiple other manifestations of fetal exposure to these autoantibodies which are not widely appreciated and rarely diagnosed. The importance of identifying affected fetuses lies in t...

Six hermetically sealed single cell rechargeable mercury-zinc pacemakers (B.T.) that will run continuously for over 4 years between rechargings have paced dogs with complete heart block for from 2 to 3 years. To maintain full cell capacity (over 1,000 mA hours) requires recharging for from 2-3 min/day to 60 to 80 hr once every 4 years, with any variation between these extremes being acceptable....
