[Cardiopulmonary resuscitation performed by laymen--the Nord-Gudbrandsdal Project--circulatory arrest in sparsely populated regions].

Previous investigations from densely populated areas have shown that more patients with prehospital circulatory arrest caused by ischemic heart disease can be successfully treated by strengthening a chain of survival. This chain consists of immediate alarm followed by prompt cardiopulmonary resuscitation, early defibrillation and advanced medical support before transportation to hospital. This paper describes the methods used in the training of lay people in cardiopulmonary resuscitation, as well as how ambulance personnel were trained to use a semiautomatic defibrillator. During the period 1987-89 11.7% of the inhabitants in Nord-Gudbrandsdal attended a course in heart lung resuscitation and all the ambulance personnel were trained and certified to use Heartstart 2000 semiautomatic defibrillators.

[Results of treatment--the Nord-Gudbrandsdal Project--circulatory collapse in sparsely populated regions].

In Project Nord-Gudbrandsdal we aimed to reduce prehospital mortality from myocardial infarction in a sparsely populated area. The ambulance system consisted of local ambulances with semi-automatic defibrillators (the ambulance personnel were trained in the use of these), combined with advanced medical support from the local doctor and/or the air ambulance doctor. During the three-year period (1987-89) 75 prehospital cardiac arrests were observed in a population of 22,000 inhabitants. 12 patients with ventricular fibrillation were defibrillated, and eight primarily with success. Four patients were discharged from hospital in a satisfactory condition. We discuss the factors determining successful resuscitation.

M-mode echocardiography in patients with severe congestive heart failure. A subgroup analysis in the Cooperative North Scandinavian Enalapril Survival Study (CONSENSUS).

In the CONSENSUS study, M-mode echocardiography was used as an optional examination. All patients were in severe congestive heart failure [New York Heart Association (NYHA) functional class IV], and all patients had radiologically marked increased heart size. Of 253 patients, M-mode echocardiography was done at baseline in 105 patients. M-mode echocardiographic recordings from 70 patients were received, and of these, only 54 patients (77%) had recordings of acceptable quality for evaluation. At follow-up, M-mode echocardiography was done after 6 weeks, 6 months and 12 months. However, because of the high mortality and the premature cessation of the study, only a limited number of patients had M-mode echocardiographic registrations after greater than 6 weeks. All M-mode echocardiographic registrations were analysed by 2 investigators independently. Systolic time interval (STI) decreased from 0.58 to 0.48 (p less than 0.05) in the enalapril group after 6 weeks. In the placebo group, a small increase in STI from 0.54 to 0.56 (not significant) was seen after 6 weeks. The decrease in STI in the enalapril group was secondary to an increase in left ventricular ejection time. No significant change was seen in left ventricular and left atrial diameters at follow-up: this finding can be explained by a type 2 error. These findings indicate an increased STI in the enalapril-treated group, which could explain why enalapril treatment reduced mortality in the CONSENSUS study.
