Electrocardiographic Comparison Between Artificial Cardiac Stimulation of Apex, Septum and Right Ventricular Outflow Tract [PDF]

Journal of Cardiac Arrhythmias, 2020
Background: Ventricular pacing is detrimental to cardiac function, with more deleterious effects when it is apical, widening the QRS complex, so the best cardiac pacing site is still being sought.

β-Adrenergic receptor-PI3K signaling crosstalk in mouse heart: elucidation of immediate downstream signaling cascades.

PLoS ONE, 2011
Sustained β-adrenergic receptors (βAR) activation leads to cardiac hypertrophy and prevents left ventricular (LV) atrophy during LV unloading. The immediate signaling pathways downstream from βAR stimulation, however, have not been well investigated. The

Acute effects of euglycemic‐hyperinsulinemia on myocardial contractility in male mice

Physiological Reports, 2022
Type 2 diabetes and obesity are associated with increased risk of cardiovascular disease, including heart failure. A hallmark of these dysmetabolic states is hyperinsulinemia and decreased cardiac reserve.

Estimulação cardíaca com tele-anodo: uma nova técnica para estimulação elétrica do coração Cardiac stimulation with tele-anode: a new technique for electrical pacing of the heart

Brazilian Journal of Cardiovascular Surgery, 1986
Os geradores unipolares, unicâmara, ou dupla-câmara podem ser inibidos, ou deflagrados por ação de miopotenciais esqueléticos. Na experiência dos autores, estas complicações ocorrem em mais de 70% dos casos.

Chronic optical pacing conditioning of h-iPSC engineered cardiac tissues

Journal of Tissue Engineering, 2019
The immaturity of human induced pluripotent stem cell derived engineered cardiac tissues limits their ability to regenerate damaged myocardium and to serve as robust in vitro models for human disease and drug toxicity studies.
