Automatic Mode Switching in Atrial Fibrillation [PDF]
, 2005 Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]
, 2012 Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Despite achieving complete revascularization, patients with coronary artery disease (CAD) may experience adverse outcomes, potentially attributable to coronary microvascular dysfunction (CMD). Coronary flow reserve (CFR), which integrates both epicardial and microvascular coronary function, and a reduced CFR following complete ...

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]
, 2016 The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Mortality in patients with cardiogenic shock (CS) remains high despite advanced treatment strategies in CS patients, underlining the need for the identification of predictors of prognosis in CS patients. Therefore, the present study investigates the prognostic impact of coronary chronic total occlusions (CTO) in patients with CS ...

New model of ventricular fibrillation [PDF]
Journal of Electrocardiology, 2005 The purpose of this study was to develop a more efficient and stable model of ventricular fibrillation (VF) in the isolated rabbit heart, because there is not a satisfactory model with this animal. We also observed the effects of increasing extracellular calcium in the stability and reversibility of the arrhythmia.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Dual antiplatelet therapy (DAPT), comprising acetylsalicylic acid and a P2Y12 receptor inhibitor such as clopidogrel, is the cornerstone of management in patients undergoing percutaneous coronary intervention (PCI). While conventional loading doses of acetylsalicylic acid and clopidogrel are well established, there is limited ...
