BACKGROUND: Limited information exists about detailed clinical characteristics and management of the small subset of Brugada syndrome (BrS) patients who had an arrhythmic event (AE). OBJECTIVES: To conduct the first nationwide survey focused on BrS patients with documented AE. METHODS: Israeli electrophysiology units participated if they had treated BrS patients who had cardiac arrest (CA) (lethal/aborted; group 1) or experienced appropriate therapy for tachyarrhythmias after prophylactic implantable cardioverter defibrillator (ICD) implantation (group 2)...

Sudden cardiac death is a leading cause of death worldwide, mainly caused by highly disturbed electrical activation patterns in the heart. Currently, murine models are the most popular model to study underlying molecular mechanisms of inherited or acquired cardiac electrical abnormalities, although the numerous electrophysiological discrepancies between mouse and human raise the question whether mice are the optimal model to study cardiac rhythm disorders. Recently it has been uncovered that the zebrafish cardiac electrophysiology seems surprisingly similar to the human heart, mainly because the zebrafish AP contains a clear plateau phase and ECG characteristics show alignment with the human ECG...

Frequency-domain indices of Heart Rate Variability (HRV) have been used as a marker of sympathovagal balance. However, they have been shown to be degraded by inter-individual or task-dependent variability, and especially breathing frequency. The study introduces a new method for analyzing respiratory (vagally) mediated Heart Rate Variability, to better assess subtle variations in sympathovagal balance, using ECG information. We evaluated the sensitivity of our new method comparatively to classic HRV analyses with cognitive workload...

CONTEXT: The 12-lead electrocardiogram (ECG) is an integral part of the diagnostic tools available for recognising a patient who is experiencing an ST-segment elevated myocardial infarction (STEMI). Consequently, a great emphasis is placed on the rapid acquisition and expert interpretation of the 12-lead ECG so that the appropriate reperfusion management might be commenced to optimise patient outcomes by preventing further damage to the myocardium. With the advancement of telemetric and diagnostic abilities of the modern ECG machine, the role of frontline rural emergency clinicians is as important as ever...

Background: The electrocardiogram (ECG) is the most used diagnostic tool in medicine; in this sense, it is essential that medical undergraduates learn how to interpret it correctly while they are still on training. Naturally, they go through classic learning (e.g., lectures and speeches). However, they are not often efficiently trained in analyzing ECG results. In this regard, methodologies such as other educational support tools in medical practice, such as educational software, should be considered a valuable approach for medical training purposes...

Acute myocardial infarction (AMI) has a high mortality rate and poor prognosis for patients. The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction (TIMI) risk score, which can be used to predict the prognosis and the need for revascularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance...

A 57-year-old male former smoker presented to the Emergency Department (ED) with blurry vision, headache, and generalized weakness. He was hypoxic on room air and ECG showed sinus tachycardia. A CT pulmonary angiogram was ordered in the ED and revealed no pulmonary embolism but incidentally noted a likely significant stenosis in the proximal LAD. Subsequent cardiac catheterization revealed a 90% stenotic lesion with percutaneous coronary intervention leading to symptom resolution. Unlike coronary CTA, CTPA is performed with non-ECG gated helical scanning and generates motion artifacts associated with myocardial contraction...

BACKGROUND: The majority of patients presenting to the ED with cardiac sounding chest pain have a non-diagnostic ECG and the problem of differentiating those suffering an acute coronary syndrome from those without is familiar to all ED clinical staff. To stratify risk in these patients, specific scores have been developed. Recent work has focused on incorporating newer high-sensitivity cardiac troponin (hs-cTn) assays; however, issues regarding performance and availability of these assays remain...

Our contribution focuses on the characterization of sleep apnea from a cardiac rate point of view, using Recurrence Quantification Analysis (RQA), based on a Heart Rate Variability (HRV) feature selection process. Three parameters are crucial in RQA: those related to the embedding process (dimension and delay) and the threshold distance. There are no overall accepted parameters for the study of HRV using RQA in sleep apnea. We focus on finding an overall acceptable combination, sweeping a range of values for each of them simultaneously...

Because aggressive driving often causes large-scale loss of life and property, techniques for advance detection of adverse driver emotional states have become important for the prevention of aggressive driving behaviors. Previous studies have primarily focused on systems for detecting aggressive driver emotion via smart-phone accelerometers and gyro-sensors, or they focused on methods of detecting physiological signals using electroencephalography (EEG) or electrocardiogram (ECG) sensors. Because EEG and ECG sensors cause discomfort to drivers and can be detached from the driver's body, it becomes difficult to focus on bio-signals to determine their emotional state...

INTRODUCTION: The sensitivity of a given test to detect a treatment-induced effect in a variable of interest is intrinsically related to the variability of that variable observed without treatment and the number of observations made in the study (i.e. number of animals). To evaluate test sensitivity to detect drug-induced changes in myocardial contractility using the variable LVdP/dtmax , a HESI-supported consortium designed and conducted studies in chronically instrumented, conscious dogs using telemetry...

Understanding arrhythmias and their treatment is not always easy. The current straightforward approach with catheter ablation and device therapy is an amazing achievement, but does not make management of underlying or other cardiac disease and pharmacological therapy unnecessary. The goal of this paper is to describe how much of the knowledge of the 1980s and early 1990s can and should still be applied in the modern treatment of patients with arrhythmias. After an introduction, this review will focus on paroxysmal atrial fibrillation and a prototype of 'idiopathic' ventricular arrhythmias, two diseases with a striking similarity, and will discuss the arrhythmogenesis...

Background: Malaria prevention and treatment are big challenges for the French forces deployed in sub-Saharan Africa. Since December 2013, 1,800 French soldiers have been deployed at any one time in the Central African Republic in the framework of "Operation Sangaris" and European Union Force (EUFOR). Over the 2014-2015 period, about 500 cases of malaria were notified in these troops during the operation or after their return (annual incidence: 13.4 p.100 person-year). The recommendation to use dihydroartemisinin-piperaquine (DHA-PQ) as the first-line treatment for French soldiers suffering from uncomplicated Plasmodium falciparum malaria in endemic areas is not always followed in practice in the field by French military general practitioners (GPs)...

Carbon monoxide (CO), a toxic gas produced via incomplete fossil fuel combustion, has several poisonous effects in the heart including induction of necrosis, apoptosis, and electrocardiogram (ECG) changes. Magnesium sulfate (MS) is a drug with cardioprotective effects especially when used after ischemia/reperfusion. In the current study, we aimed to evaluate MS cardioprotective effects following CO poisoning. Animals were exposed to CO 3000 ppm for 1 h and immediately after the exposure period and on the next 4 days (a total of 5 consecutive doses given on a daily basis), MS (75, 150 and 300 mg/kg) was injected intraperitoneally (i...

There is a pressing clinical need to develop accurate, efficient non-contrast magnetic resonance angiography (NC-MRA) techniques. Our efforts in the field have focused on a novel non-subtractive technique called quiescent-interval slice-selective (QISS) MRA. Compared with other NC-MRA techniques, QISS has the advantage of being more accurate while enabling a simpler and more efficient workflow. The original implementation, which uses electrocardiogram (ECG) gating and a Cartesian k-space trajectory, is a reliable technique for the evaluation of peripheral arterial disease (PAD)...
