Persistent inappropriate sinus tachycardia after radiofrequency ablation of left lateral accessory pathway
(Blackwell PublishingOxfordInglaterra, 2006)
Vascularização arterial da região do nó sinoatrial em corações suínos: origem, distribuição e quantificação
(Rio de Janeiro, 2008)
O nó sinoatrial, por se encontrar topograficamente instalado como componente inicial do sistema de condução, é responsável pela geração dos impulsos nervosos determinantes da contração cardíaca. Estudos relacionados à ...
GPCR-dependent biasing of GIRK channel signaling dynamics by RGS6 in mouse sinoatrial nodal cells
(National Academy of Sciences, 2020)
Abstract: How G protein-coupled receptors (GPCRs) evoke specific biological
outcomes while utilizing a limited array of G proteins and effectors
is poorly understood, particularly in native cell systems. Here, we
examined ...
Características morfológicas y posibles implicaciones clínicas de las arterias nodales: morphological characteristics and potential clinical implications of nodal arteries
(2010-09-23)
The morphological expression of nodal arteries is important in the diagnosis and management of
cardiac clinical events and surgical approaches. 88 nodal arteries of hearts obtained from autopsies
were studied. Coronary ...

Ivabradine: Just another New Pharmacological Option for Heart Rate Control?
(2011)
Ivabradine (IVB) is a heart rate lowering agent that acts via selective inhibition of the pacemaker funny current in sinoatrial nodal P cells, thus, reducing heart rate at rest and during exercise with minimal effect on ...
Sinus node function in patients operated for mitral valve disease: indirect evaluation with epimyocardial electrodes
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2008)
PURPOSE: To study the interatrial conduction times and atrial node performance in patients submitted to mitral valve surgery with the aid of temporary atrial epicardic electrodes. METHODS: The atriograms were carried out ...
Controle autonômico dos ajustes cardíacos associados à digestão no lagarto herbívoro Iguana iguana (Linnaeus, 1758)
(Universidade Estadual Paulista (Unesp), 2021-08-31)
Os ajustes cardiovasculares que ocorrem após a alimentação são essenciais para suprir as demandas da digestão em vertebrados. Répteis carnívoros, por exemplo, apresentam ajustes cardiovasculares de grande magnitude em ...
