Summary: During a baseline cardiovascular survey PR was measured in a strictly standardized way in 1832 men aged 40-59 years, free from coronary heart disease (CHD). Of 1758 men still alive, 1585 underwent an identical follow-up study 7 years later. A total of 1570 were in sinus rhythm. The following findings were made: (1) Baseline and follow-up prevalence of a prolonged PR ( 2 0 . 2 2 s) was identical (5.3 vs. 5.4%). (2) Only 60% of restudied men with a prolonged PR also had prolonged PR at follow-up. (3) Only 1 of 98 with a prolonged baseline PR had a more advanced AV block at follow-up, whereas an additional 4 had conditions which might influence the AV node (1 Bechterew's disease and 3 mild aortic valve stenosis). (4) The incidence of all CHD events found during the follow-up study (CHD deaths, myocardial infarction, angina pectons, and pathologic exercise ECGs) was moderately but significantly lower in men with a prolonged PR than among men with a PR 1 0 . 2 1 s. Thus a prolonged PR is rarely an indicator of impending, more severe conduction disturbances; it is mostly a benign, functional find- ing in middle-aged men free from overt heart disease and is not positively associated with CHD. Rather PR may be moderately and inversely associated with latent CHD.

“…Studies of healthy populations have presented very few cases of second and third degree atrioventricular (AV) blocks (Averill et al, 1960;Hiss and Lamb, 1962;Johanson, 1966;Mathewson and Varnam, 1960;Rumball and Acheson, 1963;Stewart and Manning, 1944). Little is known of the existence of possible warning signs of such advanced AV blocks.…”

SummaryObjectives: To evaluate if radiofrequency catheter ablation is an effective procedure for the treatment of right ventricular outflow tract premature ventricular contraction (RVOT-PVC) and ascertain if it results in an improvement of symptoms.Methods: A prospective study with 30 consecutive patients (mean age 40 ± 13 years, 25 females), with no apparent structural cardiopathy, with very frequent (mean density of 1,263 ± 593/h) RVOT-PVC, symptomatic for more than one year (mean = 74 months) and resistant to antiarrhythmic drugs (3 ± 1.7, including beta-blockers), who underwent radiofrequency catheter ablation.Results: After the first procedure, there were 23 initial successful cases (76.6%) and 7 initial failures (23.4%). Four patients experienced relapses, two of whom did not undergo the second procedure. The second procedure was carried out in 9 patients (7 initial failures and 2 relapses), and there was success in 5 additional patients, one of them by epicardial access. The final success rate was 80% (24/30), and there were no major complications. After a mean follow-up of 14 ± 6 months, in the successful group there was a reduction greater than 90% in density of premature ventricular contractions (PVC) (24/24; p<0.0001) and a resulting absence of symptoms in the majority of patients (23/24; p<0.001).Conclusion: Radiofrequency catheter ablation is a safe and effective treatment for patients with persistent and symptomatic PVC with RVOT morphology.

“…34"~ Digoxin has no role acutely as it may accelerate anomalous conduction and precipitate malignant ventricular arrhythmias. 36 Lidocaine has previously been advocated as the treatment of choice during general anaesthesia for SVT's with anomalous conduction because it depresses the accessory pathway. 19.37 It was used successfully in two of our patients; however, its use in WPW cannot be recommended, since it increases AV CANADIAN JOURNAL OF ANAESTHESIA conductance and has been reported to cause ventricular fibrillation when given during atrial fibrillation.…”
