Paroxysmal ventricular fibrillation in children. Long-term follow-up of three cases treated with beta-blocking agents.

A long-term follow-up report is given on three children with stress-induced bursts of ventricular activity, occasionally proceeding to ventricular fibrillation causing syncope. All patients were treated with a beta-blocking agent as prophylaxis for 12, 10 and 6 years, respectively. Case 1 has no signs of organic heart disease. She has been followed from the age of 8 years and had her last syncope in 1974. She was last seen in Nov. 1976, doing well at the age of 20. Case 2 started having syncopes after an attack of measles at the age of 8 years, at which time she probably acquired some damage to her myocardium. She had persistent bradycardia but no other signs of heart disease. She had an uneventful pregnancy and delivery in 1973 and gave birth to a normal child. She died suddenly in 1974, at the age of 22, four years after her last syncopal attack. Case 3 had cardiomyopathy with increasing heart size and exertional dyspnoea and marked ischaemic ECG changes during exercise. He was followed from the age of 7 years. He died suddenly in 1974 at the age of 16, four years after his last syncope.

Chronic supraventricular tachycardia in infancy and childhood.

The results of a one to 19 year follow-up study of 9 children with supraventricular tachycardia of more than one month's duration are reported. The ECG diagnosis of tachycardia was made before birth in one patient and between the ages of 8 months and 12 years in 8. Four had sustained and 4 had repetitive tachycardia, while one patient had both patterns at different times. Reciprocal rhythm was diagnosed in 3 patients and exit block in 2. Severe symptoms had occurred in 2 patients, but as a rule symptoms were mild or absent. No treatment abolished the arrhythmias but digitalis reduced the overall ventricular rate in 6 patients. After a duration of 1-7 years, 3 patients still had tachycardia at the follow-up. In the remaining 6 patients the tachycardia had subsided 7 months to 10 years after the onset.

Adams-Stokes seizures due to ventricular tachydysrhythmias in patients with heart block: prevalence and problems of management.

One hundred and twelve patients with heart block and chronic tendency to syncope were ECG-monitored during syncope. Ventricular tachycardia and/or fibrillation (VT-VF) was observed as the cause of syncope in 11 patients: in 6 of 20 patients with chronic third degree A-V block, in 3 of 65 with paroxysmal A-V block and in 2 of 27 with S-A block. The R-R interval preceding the escape beat which initiated VT-VF varied between 1.2 and 2.2 seconds. The cerebral attacks were amenable to long-term pacemaker treatment. However, relapses of VT-VF were observed during pacing with a low rate of 55 per minute and during short interruptions in pacing, as produced by intermittent pacemaker failure or threshold determination. In one patient, supplementary treatment with a beta-blocking agent had to be given to suppress exercise-induced attacks of VT-VF after pacemaker implantation.
