Destabilizing effects of mental stress on ventricular arrhythmias in patients with implantable cardioverter-defibrillators.
BACKGROUND The incidence of sudden cardiac death increases in populations who experience disasters such as earthquakes. The physiological link between psychological stress and sudden death is unknown; one mechanism may be the direct effects of sympathetic arousal on arrhythmias. To determine whether mental stress alters the induction, rate, or termination of ventricular arrhythmias, we performe...
متن کاملOptogenetic termination of ventricular arrhythmias in the whole heart: towards biological cardiac rhythm management
Aims Current treatments of ventricular arrhythmias rely on modulation of cardiac electrical function through drugs, ablation or electroshocks, which are all non-biological and rather unspecific, irreversible or traumatizing interventions. Optogenetics, however, is a novel, biological technique allowing electrical modulation in a specific, reversible and trauma-free manner using light-gated ion ...
متن کاملFrequency of Cardiac Arrhythmias in Patients with Aluminum Phosphide Poisoning
Background: Cardiac failure is the major lethal consequence of aluminum phosphide (AlP) poisoning. This study was designed to determine the frequency of cardiac arrhythmias in patients with AlP poisoning. Methods: In this prospective cross-sectional study, patients with definitive history of AlP poisoning treated at emergency department of Allied Hospital Faisalabad, Faisalabad, Pakistan, from ...
متن کاملThree-dimensional panoramic imaging of cardiac arrhythmias in rabbit heart.
Cardiac fluorescent optical imaging provides the unique opportunity to investigate the dynamics of propagating electrical waves during ventricular arrhythmias and the termination of arrhythmias by strong electric shocks. Panoramic imaging systems using charge-coupled device (CCD) cameras as the photodetector have been developed to overcome the inability to monitor electrical activity from the e...
متن کاملEffects of Chronic Oral Administration of Natural Honey on Ischemia/Reperfusion-induced Arrhythmias in Isolated Rat Heart
Objective(s) In this study, effects of chronic administration of oral natural honey against ischemia/reperfusion (I/R)- induced cardiac arrhythmias were investigated in isolated rat heart. Materials and Methods Male Wistar rats were divided into four groups (n= 10-14 rats in each group) and fed with natural honey (1%, 2% and 4% dissolved in the drinking water) for 45 days except for the con...
