Prevalence and morbidity of heart block in Devon.
In a survey in the Exeter area 139 patients with some degrees of abnormal atrioventricular conduction were notified by 282 family doctors. Per 100,000 of the population the prevalence of second-degree and thrid-degree heart block was estimated to be 17.3, of complete block past or present 15.6, and of complete block at the time of survey 13.1. Heart block was commoner in men than women, the sex ratio being 1.4 to 1; its prevalence increased steeply with age, and the morbidity rate was less than that reported by others. If the morbidity figures quoted in this survey are representative of the general population, it reaffirms the policy that pacemakers should be recommended for selected patients only.
Analysis of an open electrocardiograph referral service for family doctors.
The results of a questionary to investigate an open electrocardiograph (E.C.G.) service for family doctors suggest that the service is useful in diagnosis (26% of the E.C.G. reports were unexpected) and in management (the result of the E.C.G. led to specific treatment or alteration to regimen in 22% of cases and in a further 46% to reassurance). The results suggest that during the 45 weeks of the study many outpatient appointments were avoided.Undoubtedly an open E.C.G. service allows the family doctor to give a quicker and better service to his patients. For this reason and because of operational benefits to the hospital the service must be recommended.

Labor analgesia with paravertebral lumbar sympathetic block.
BACKGROUND AND OBJECTIVES: Provision of labor analgesia continues to be a challenge for parturients with spine pathology or history of back surgery. METHODS: We report on the use of paravertebral lumbar sympathetic block for first stage labor analgesia in two parturients with spine pathology.
