Efeitos da estimulação ventricular convencional em pacientes com função ventricular normal Efectos de la estimulación ventricular convencional en pacientes con función ventricular normal Conventional ventricular stimulation effects on patients with normal ventricular function

Arquivos Brasileiros de Cardiologia, 2009
FUNDAMENTO: A estimulação de ventrículo direito pode ser deletéria em pacientes com disfunção ventricular, entretanto há poucas evidências sobre o impacto dessa estimulação em pacientes com função normal.

Empowering artificial intelligence in characterizing the human primary pacemaker of the heart at single cell resolution

Scientific Reports
The sinus node (SN) serves as the primary pacemaker of the heart and is the first component of the cardiac conduction system. Due to its anatomical properties and sample scarcity, the cellular composition of the human SN has been historically challenging

Transcriptional Response of Circadian Clock Genes to an ‘Artificial Light at Night’ Pulse in the Cricket Gryllus bimaculatus

bioRxiv, 2022
Light is the major signal entraining the circadian clock that regulates physiological and behavioral rhythms in most organisms, including insects. Artificial Light at Night (ALAN) disrupts the natural light-dark cycle and negatively impacts animals at ...

Transaxillary Subpectoral Placement of Cardiac Implantable Electronic Devices in Young Female Patients

Archives of Plastic Surgery, 2017
Background The current indications of cardiac implantable electronic devices (CIEDs) have expanded to include young patients with serious cardiac risk factors, but CIED placement has the disadvantage of involving unsightly scarring and bulging of the ...

Myocardial threshold in patients with artificial pacemakers [PDF]

The American Journal of Cardiology, 1966
Abstract A method for estimating myocardial threshold in patients with implanted artificial pacemakers has been described. By the external application of a calibrated suppression signal, the output of the implanted unit can be gradually reduced until the myocardial response ceases. The threshold level thus determined can be expressed as a per cent of
