“…Patients in their eighties paced for complete heart block can expect to survive as long as others of the same age and sex without heart block. 26 Our results suggest that this is so for nonagenarians paced for complete heart block as well. As previously reported,26'27 a history of ischaemic heart disease is important in determining survival after pacing for complete heart block.…”

Summary:We report our experience of 20 patients who have had permanent pacemakers implanted for the first time after the age of90. The main indications were syncope or presyncope which occurred in 15 patients. Complete heart block was present in 14 patients. Syncopal and presyncopal symptoms were cured in 73%. Nonagenarians paced for complete heart block can expect to survive for as long as others of the same age without heart block. Permanent pacing is an effective and appropriate treatment in the very old.

“…Third‐degree A‐V block is sometimes connected with hypertension, but more frequently with coronary artery disease [16, 17]. However, chronic total A‐V block is associated with fibrous degeneration of the conducting system in 40% of cases [18–24]. This particularly applies in the elderly population [19].…”

“…In chronic third‐degree A‐V block the implantation of a pacemaker is associated with improved prognosis [15, 21]. However, patients under 60 with third‐degree A‐V block have a poorer prognosis than control patients without a block, although this does not apply to older patients.…”

Abstract. Kojic EM, Hardarson T, Sigfusson N, Sigvaldason H (National University Hospital and Heart Preventive Clinic, Reykjavik, Iceland). The prevalence and prognosis of third-degree atrioventricular conduction block: the Reykjavik Study. J Intern Med 1999; 246: 81±86.Objectives. The objectives of this study were to find the prevalence of third-degree atrioventricular block in representative population sample and to estimate its prognostic significance. Most earlier studies have been performed on hospital patients and some professional groups. Setting and subjects. In the Reykjavik Study, a prospective cardiovascular population study, 9139 men and 9773 women aged 33±79 years were examined in 1967±91. Electrocardiograms were taken and coded according to the Minnesota code.Third-degree atrioventricular block was found in 11 persons, seven male and four female, an overall prevalence of 0.04%. All of these individuals had signs of dysrhythmia on electrocardiograms taken later, and in addition some other heart disease. The heart block was temporary in seven individuals (64%); six (55%) needed a pacemaker. Conclusions. The prevalence of third-degree atrioventricular block in this general population was low. The block was temporary in the majority of subjects. All had some underlying heart disease, which may affect the prognosis more than the heart block. Fewer subjects than expected were found to need a pacemaker.

“…A number of clinical reports claim that CHD plays an important role in the development of AV blocks (e.g., Forsberg, 1978;Ginks et a/. , 1979, 1980: Otterstad et ul., 1981Shaw and Kekwick, 1978: Sid- dons, 1974).…”

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.
