REVIEW
Gumpeny Ramachandra Sridhar, Narasimhadevara Santhi Nirmala Sanjana
Synchrony of biological processes with environmental cues developed over millennia to match growth, reproduction and senescence. This entails a complex interplay of genetic, metabolic, chemical, light, hormonal and hedonistic factors across life forms. Sleep is one of the most prominent rhythms where such a match is established. Over the past 100 years or so, it has been possible to disturb the synchrony between sleep-wake cycle and environmental cues. Development of electric lights, shift work and continual accessibility of the internet has disrupted this match...

: Knowledge of the mechanism underlying post-operative atrial fibrillation (PoAF) is essential for development of preventive measures. The incidence and characteristics of both PoAF and supraventricular premature beats triggering PoAF, their interrelationship and alterations over time have never been examined. The goal of this study is therefore to examine the correlation between the incidence and characteristics of supraventricular premature beats (SVPBs) and PoAF episodes in patients undergoing CABG in the first five post-operative days...

BACKGROUND: Brugada pattern can be found on the electrocardiogram (ECG) of patients with altered mental status, usually with fever or drug intoxication. Diagnosis remains challenging, because the ECG changes are dynamic and variable. In addition, triggers are not always clearly identified. In patients with atrial fibrillation (AF), the use of class IC antidysrhythmic drugs can unmask a Brugada pattern on the ECG, especially if combined with other medications acting on sodium channels...

Loperamide is an over-the-counter antidiarrheal with opioid-receptor agonist properties. Recommended over-the-counter doses (range = 2-8 mg daily) do not produce opioid effects in the central nervous system because of poor oral bioavailability and P-glycoprotein efflux* of the medication (1); recent reports suggest that large doses (50-300 mg) of loperamide produce euphoria, central nervous system depression, and cardiotoxicity (2-4). Abuse of loperamide for its euphoric effect or for self-treatment of opioid withdrawal is increasing (5)...

STUDY OBJECTIVE: Loperamide abuse has been increasing in the United States as a potential alternative to manage opioid withdrawal symptoms or to achieve euphoric effects of opioid use. In June 2016, the Food and Drug Administration warned health care providers and the general public about potential serious adverse outcomes, including cardiac dysrhythmias and death. The purpose of this study is to determine recent trends in intentional loperamide abuse and misuse, reported clinical effects and management, and medical outcomes as reported to poison centers across the United States...

INTRODUCTION: Myocardial bridging (MB) is a congenital variant of the coronary artery in which a portion of the epicardial coronary artery takes an intramuscular course. Although it is considered a benign anomaly, it may lead to such complications as myocardial ischaemia, acute coronary syndrome, coronary spasm, exercise-induced dysrhythmias or even sudden death. MB may be related to increased inflammatory and atherosclerotic processes. This study was conducted with the aim of evaluating the relationship between neutrophil/lymphocyte ratio (NLR) and MB...

INTRODUCTION: The development of implantable technology for cardiac rhythm management remains one of the seminal achievements of the second half of the 20th century. The development of artificial pacemakers for the electrical control of the cardiac rhythm has greatly enhanced the physician's ability to treat cardiac dysrhythmias. An ageing population and the extension of indications will in all probability result in an increasing number of cardiac device implantations. OBJECTIVE OF STUDY: To study mortality and morbidity in patients with permanent pacemaker implantation at a tertiary care hospital in North India...

OBJECTIVE: Adverse cardiovascular events (ACVEs) account for a large proportion of the morbidities and mortalities associated with drug overdose emergencies. However, there are no published reports regarding outcomes of ACVEs associated with acute dapsone poisoning. Here, the authors retrospectively analyzed ACVEs reported within 48 hours of treatment in patients with acute dapsone poisoning and assessed the significance of ACVEs as early predictors of mortality. METHODS: Sixty-one consecutive cases of acute dapsone poisoning that were diagnosed and treated at a regional emergency center between 2006 and 2014 were included in the study...

BACKGROUND: Right ventricular dysfunction (RVD) in pulmonary embolism (PE) has been associated with increased morbidity. Tools for RVD identification are not well defined. The prognostic value of RVD markers to predict serious adverse events (SAE) during hospitalization is unclear. OBJECTIVE: Prospectively compare the incidence of SAE in normotensive emergency department patients with PE based upon RVD by goal-directed echocardiography (GDE), cardiac biomarkers, and right-to-left ventricle ratio by computed tomography (CT)...

BACKGROUND: Ventricular tachycardia (VT) and ventricular fibrillation are the causes of approximately 300,000 deaths per year in the United States. VT is classified based on hemodynamic status and appearance. Stable, monomorphic VT treatment is controversial. OBJECTIVE: Our aim was to provide emergency physicians with an evidence-based review of the medical management of stable, monomorphic VT. DISCUSSION: Stable, monomorphic VT is part of a larger class of ventricular dysrhythmias defined by a rate of at least 120 beats/min with QRS > 120 ms without regularly occurring P:QRS association...

BACKGROUND: Brugada syndrome is a genetic disorder that increases an individual's risk for sudden cardiac death and ventricular dysrhythmias that was first described by the Brugada brothers in 1992. Brugada syndrome is characterized by an atypical electrocardiogram pattern that includes a bundle branch block and ST-segment elevation in the precordial leads. CASE REPORT: A 74-year-old man had a cardiac arrest at the time of a low-speed motor vehicle collision. When emergency medical services arrived, the patient was in torsades de pointes...

Congenital heart defects are associated with various physiological disturbances. They pose anesthetic challenges for both cardiac and noncardiac surgeries. Atrioventricular septal defects are due to a developmental failure in the separation of atria and the ventricles into separate chambers and failure in the separation of mitral and tricuspid valves. We present a case of a child (1½ years), weighing 10 kg, diagnosed as congenital hydrocephalus who was planned for ventriculoperitoneal shunt. Child was having an oxygen saturation of 76% on room air...

Routine screening and accurate diagnosis of chronic gastrointestinal motility disorders represents a significant problem in current clinical practice. The electrogastrography (EGG) provides a non-invasive option for assessing gastric slow waves, as a means of diagnosing gastric dysrhythmias, but its uptake in motility practice has been limited partly due to an incomplete sensitivity and specificity. This paper presents the development of a human whole-organ gastric model to enable virtual (insilico) testing of gastric electrophysiological dispersion in order to improve the diagnostic accuracy of EGG...
