Potential Prevention of Pacing‐Induced Heart Failure Using Simple Pacemaker Programming Algorithm

Abstract

Predominant RVP in patients without symptoms of HF at baseline may be responsible for worse performance in cardiopulmonary exercise test, higher BNP concentrations and impairment of LV function. Specific DDDR pacemaker programming promotes intrinsic AV conduction and may prevent the development of pacing-induced HF.

Cardiomyopathy Associated with Right Ventricular Apical Pacing-Systematic Review and Meta-Analysis

“…After the exclusion of duplicates and non-relevant studies, 36 studies were retrieved for further full-text evaluation by reviewing study titles and abstracts. We further excluded three studies that were projected in cross-over manner [ 4 , 5 , 6 ], six trials that did not evaluate LVEF in the follow-up [ 7 , 8 , 9 , 10 , 11 , 12 ], seven studies in which information about RVAP was absent or RVAP was <20% [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ], three studies in which patients were treated according to the ‘’ablate and pace” method [ 20 , 21 , 22 ], one trial with a short-term follow-up [ 23 ], one trial which was a prolonged follow-up of the so far included study, and one study because of statistical issues [ 24 ]. Finally, fourteen randomized controlled studies published in the period of 2008–2017 were included in this systematic review and meta-analysis.…”

Avaliação de dessincronia atrioventricular em portadores de marca-passo bicameral devido à doença do nó sinusal e bloqueio atrioventricular de primeiro grau

“…Desde os anos 90, diversas publicações sustentam os benefícios aparentes da minimização da ECA do VD 2,15,16,25,31,34,79,[91][92][93][94][95][96][97] . O %CEV pode, de fato, ser substancialmente reduzido a partir dos algoritmos de operação baseados nos átrios 9,13,15,19,28,83,98 O encurtamento sistólico dos miócitos prematuramente ativados pelo estímulo desde o sítio de implante do eletrodo de ECA (monofocal) resulta em estiramento dos miócitos contralaterais modificando negativamente a fase pré-ejetiva ventricular.…”
