“…The electrocardiographic reports followed the criteria defined by the Brazilian Guidelines on Electrocardiography. 29 The criterion used to recommend a permanent pacemaker still in the operating room after the TAVI was implanted was the presence of high-grade AVB or intrinsic rhythm of less than 40 beats per minute during inhibition of the temporary pacemaker. Recommendations of a permanent pacemaker while in hospital were determined by a team of clinical cardiologists, electrophysiologists and intensivists, considering the Brazilian and European guidelines for the implantation of artificial cardiac pacing devices.…”

Background: Transcatheter aortic valve implantation (TAVI) has become a therapeutic option for high-risk or nonoperable patients with severe symptomatic aortic stenosis. Atrioventricular conduction disturbances requiring permanent pacemaker (PPM) are a common and clinically important complication. Objectives: To evaluate the incidence of conduction disorders (CDs) after TAVI and the need for subsequent PPM implantation. To identify the predictors of postoperative PPM implantation. Methods: Retrospective study. All patients who underwent TAVI in a public hospital from December/2011 to June/2016 were included. Multivariate analysis was conducted to establish the predictor of permanent pacemaker implantation. Survival curves were constructed by the Kaplan-Meyer method. Statistically significant variables were those with p value < 0.05. Results: 64 patients with AS underwent TAVI. Eleven patients were excluded. TAVI induced a new CD in 40 (77%) of the remaining 53 patients. The most common new CDs were 3 rd degree AV block (32%) and left bundle branch block (30%). Sixteen patients (30,2%) underwent PPM implantation during the index hospitalization. On univariate analysis the risk factors for PPM implantation were CoreValve ® use (OR: 1,76; P = 0,005), larger prosthesis implantation (P = 0,015), presence of a QRS ≥ 120 ms (OR: 5,62; P = 0,012), and 1st degree AV block (OR: 13; P = 0.008). On multivariate analysis the presence of 1st degree AV block predicted the need for PPM. Conclusion: TAVI induced CDs requiring PPM in 30% of the patients. The presence of 1st degree AV block predicted the need for PPM.

“…A surface electrocardiogram with the standard 12-lead pattern was obtained from all of the patients immediately before the procedure, after the procedure, and in the outpatient clinic of the hospital, primarily to diagnose the presence or absence of heart conduction system blockade, which was defi ned according to criteria standardized by the Brazilian Society of Cardiology [Guimarães 2003]. The results were analyzed and compared with respect to the anatomy of the main septum arterial trunk, particularly the importance of the coronary artery of origin (considering the Schlesinger classifi cation of right or left coronary artery dominance and Successful septum ablation with amputation (arrows) of the great forked septum branch and implantation of a cardioverter-defi brillator electrode.…”

“…Enquanto o intervalo PR é o espaço do eletrocardiograma que representa a despolarização atrial e o retardo fisiológico do estímulo ao passar pelo nódulo atrioventricular (AV), mostra o tempo de condução atrial; por sua vez, o intervalo QT é a porção do eletrocardiograma que corresponde ao tempo necessário para a completa excitação elétrica e a recuperação dos ventrículos, ou seja, é a duração da atividade elétrica ventricular. 1,2 O intervalo QT varia inversamente à frequência cardíaca (FC), quanto maior a FC, tanto menor o QT, e vice-versa. Assim, ele deve ser corrigido em relação à FC, essa correção gera o intervalo QTc, que é usado para a detecção da heterogeneidade da repolarização ventricular, e se caracteriza como marcador da arritmogênese provocada por tempos de repolarização não-homogêneos.…”

A escoliose é caracterizada por alterações anatomo-fisiológicas importantes. Diversos pesquisadores têm se dedicado ao estudo dos comprometimentos gerados pela escoliose, a maioria dos estudos com animais envolve utilização de modelos invasivos para indução de escoliose. O objetivo do trabalho foi avaliar se o modelo não invasivo de indução de escoliose em ratos promove modificações na funcionalidade cardíaca. Métodos: Ratos Wistar foram divididos em 2 grupos (n=8): Controle (C), escoliótico (E). Os animais do grupo escoliótico foram submetidos à utilização de um colete de PVC durante 12 semanas consecutivas para a indução da escoliose. Após, foram avaliados os seguintes parâmetros: peso dos animais, FC, SÂQR, intervalo QRS, PA, força de contração na presença de noradrenalina e o padrão dP/dt+. A análise estatística foi feita pelo teste de normalidade (Kolmogorov-Smirnov), ANOVA e post test Tukey (p menor 0,05). Quanto aos resultados, os animais do grupo (E) apresentaram menor peso; não houve diferente da FC entre os grupos; o grupo (E) apresentou desvio de 11º do SÂQRS; a duração da onda R e o intervalo PR; a força de contração e o padrão dP/dt+ não tiveram diferença entre os grupos. Desse modo, os dados sugerem que o modelo não invasivo de indução de escoliose não provoca alterações do padrão fisiológico cardíaco.
