Atrial fibrillation (AF) is common in ICU patients and is associated with a two- to fivefold increase in mortality. This paper provides a reappraisal of the management of AF with a special focus on critically ill patients with haemodynamic instability. AF can cause hypotension and heart failure with subsequent organ dysfunction. The underlying mechanisms are the loss of atrial contraction and t...

Objective: Survival-to-discharge rates following in-hospital cardiac arrest (IHCA) patients remain significantly low. The use of initial documented cardiac rhythm as predictor of Survival-to-discharge is still unclear. This study aimed to assess whether the initial documented rhythm can be used as a predictor of survival-to-discharge following IHCA in an emergency department of the tertiary car...

The effect of selective beta-receptor blockade on adrenaline-evoked ventricular arrhythmias was studied in atropinized dogs anaesthetized with halothane in oxygen. Cardiac beta-receptors were selectively blocked with ICI 50172, while the peripheral vascular beta-receptors were selectively blocked with H 35/25. ICI 50172 prevented adrenaline-evoked ventricular arrhythmias and the increase in sin...

Introduction Many features, emerging from mathematical techniques, have been used in the analysis of brain signals. In this study, the physical quantity of “moment of inertia” (MOI) was introduced as a feature to enhance high-frequency waves (HFWs) in electroencephalography (EEG). Materials and Methods In this research, the recorded EEGs from F3, F4, and Cz points in 20 males were used. A total...

A schizophrenicman ingesteda mixtureof psycho-activedrugsduringpara-suicide, andpresented with marked respiratory and psychomotor depression. Electrocardiographic abnormalities of marked junctional bradycardia, prolonged QT interval and ventricular tachyarrhythmias of the torsade de pointes type were documented. Cardioversion, lignocaine infusion, temporary cardiac pacing and beta-blockade fina...

Health technology A clinical pathway for the secondary prevention of postoperative atrial fibrillation (AF) in patients who had undergone coronary artery bypass grafting (CABG) was examined. The pathway was based on the administration of oral amiodarone, rate and rhythm control, cardioversion, and anticoagulation. Rate control, if needed, was mainly achieved with intravenous diltiazem and less ...

Atrial fibrillation (AF) usually presents to the emergency room (ED) with a rapid ventricular rate, which commonly, but not always, is symptomatic. Rate control easily managed diltiazem (DTZ) and beta blockers (BBs), typically metoprolol (MTP). Sinus rhythm frequently restored within 48 hours by means of spontaneous conversion, electrical cardioversion, or medications. However, AF recurs one ye...

Recent hypotheses on the potential role of neuronal oscillations in speech perception propose that speech is processed on multi-scale temporal analysis windows formed by a cascade of neuronal oscillators locked to the input pseudo-rhythm. In particular, Ghitza (2011) proposed that the oscillators are in the theta, beta, and gamma frequency bands with the theta oscillator the master, tracking th...

We aimed to investigate the mu rhythm in the sensorimotor area during tongue thrust observation and to obtain an answer to the question as to how subtle non-verbal orofacial movement observation activates the sensorimotor area. Ten healthy volunteers performed finger tap execution, tongue thrust execution, and tongue thrust observation. The electroencephalogram (EEG) was recorded from 128 elect...
