Place, publisher, year, edition, pagesOxford University Press (OUP): Policy B / Wiley, 2014. The underutilization of CRT was worse with increasing age. ConclusionsBoth IVCD and LBBB were more common with increasing age and were similarly strong independent predictors of mortality and in all ages. 4% and absent but with indication in 23% vs. In the three age groups, CRT was present in 6% vs. When the cardiac output becomes too low, the patient faints (syncope). The adjusted P for interaction between age and QRS morphology was 0.664. An ICD is a small device which can treat people with dangerously abnormal heart rhythms. Conduction disorder of the heart Clinical Information A condition of fainting spells caused by heart block, often an atrioventricular block, that leads to bradycardia and drop in cardiac output. 308 Cardiac arrhythmia and conduction disorders with mcc. benefit was observed in patients with a non-LBBB QRS pattern (RBBB or IVCD).10. The multivariable hazard ratio (HR) for all-cause mortality over a median (interquartile range) follow-up of 29 (12-53) months for IVCD vs. CRT is a form of cardiac pacing used in patients with systolic HF and. Among 13782 patients without CRT, IVCD was present in the three age groups in 11% vs. Methods and resultsWe studied 14713 patients with ejection fraction 39% in the Swedish Heart Failure Registry and divided into age groups 65years, 66-80years and greater than80years. We tested the hypotheses that in the elderly: (i) IVCD and LBBB are more prevalent, (ii) IVCD and LBBB are more harmful, and (iii) CRT is underutilized. The patients with IVCD had higher levels of circulating bilirubin, larger left atriums (LAs), larger right ventricle (RV) diameters, longer PR intervals, and less use of beta blockers, aspirin and spironolactone during admission. 1073-1081 Article in journal (Refereed) Published Abstract ĪimsAge is not a contraindication to cardiac resynchronization therapy (CRT), but the prevalence and prognostic impact of QRS prolongation with intraventricular conduction delay (IVCD) and left bundle branch block (LBBB), as well as CRT utilization, may differ with age. 22 These observations may not apply to all patients because these are single studies with small numbers of patients.
