Tratamento otimizado e redução da frequência cardíaca na insuficiência cardíaca crônica
Arquivos Brasileiros de Cardiologia, 2013 FUNDAMENTO: A Insuficiência Cardíaca (IC) é uma síndrome que cursa com má evolução nas formas avançadas. O bloqueio neuro-hormonal modifica essa história natural; no entanto, ele com frequência é subotimizado.

Multiscale studies of delayed afterdepolarizations II: Calcium-overload-induced ventricular arrhythmias [PDF]
arXiv, 2023 Disturbances in calcium homeostasis in a cardiac myocyte can lead to calcium-overload conditions and abnormal calcium releases, which occur primarily in the following two phases of the action potential (AP): (a) triggered or late calcium release (LCR) during the plateau phase; (b) spontaneous calcium release (SCR) during the diastolic interval (DI ...

Usefulness of Tissue Doppler Imaging to Predict Arrhythmic Events in Adults with Repaired Tetralogy of Fallot [PDF]
, 2010 INTRODUCTION: Adults with repaired tetralogy of Fallot (TOF) may be at risk for progressive right ventricular (RV) dilatation and dysfunction, which is commonly associated with arrhythmic events.

Multiscale studies of delayed afterdepolarizations I: A comparison of two biophysically realistic mathematical models for human ventricular myocytes [PDF]
arXiv, 2023 Focal arrhythmias, which arise from delayed afterdepolarizations (DADs), are observed in various pathophysiological heart conditions; these can lead to sudden cardiac death. A clear understanding of the electrophysiological factors of cardiac myocytes, which lead to DADs, can suggest pharmacological targets that can eliminate DAD-induced arrhythmias ...

A Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging [PDF]
arXiv, 2015 Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure.

Ventricular torsional relation to ventricular fiber arrangement [PDF]
arXiv, 2014 Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole.
