Neuroendocrine syncope is a newly proposed term to embody both syncope of reflex and adenosine-related etiology. Recent publications on tilt testing have revealed the presence of a hypotensive tendency in some patients, even in the face of severe cardioinhibition. This new understanding may allow better selection of older reflex syncope patients, documented by ECG loop recorder, for successful pacing where tilt testing is ideally negative for a good result in terms of few syncope recurrences and prompts a less aggressive management policy when hypotensive medication is required...

OBJECTIVE: In vitro fertilization (IVF) is increasingly used for treatment of infertile couples worldwide. The association between IVF and cancer risk in offsprings is conflicting. We present a case of atypical teratoid/rhabdoid tumor (AT/RT) in a girl conceived by IVF and present results of systematic review of literature of primary intracranial neoplasms diagnosed in children conceived by IVF. METHODS: A systematic review of literature was conducted on April 12, 2017 to identify previously published reports of intracranial brain tumors in patients conceived after IVF...

Introduction: There are over a dozen medical shows airing on television, many of which are during prime time. Researchers have recently become more interested in the role of these shows, and the awareness on cardiopulmonary resuscitation. Several cases have been reported where a lay person resuscitated a family member using medical TV shows as a reference. The purpose of this study is to examine and evaluate college students' perception on cardiopulmonary resuscitation and when to shock using an automated external defibrillator based on their experience of watching medical TV shows...

In epilepsy, seizures can evoke cardiac rhythm disturbances such as heart rate changes, conduction blocks, asystoles, and arrhythmias, which can potentially increase risk of sudden unexpected death in epilepsy (SUDEP). Electroencephalography (EEG) and electrocardiography (ECG) are widely used clinical diagnostic tools to monitor for abnormal brain and cardiac rhythms in patients. Here, a technique to simultaneously record video, EEG, and ECG in mice to measure behavior, brain, and cardiac activities, respectively, is described...

A 63-year-old man presented with an out-of-hospital cardiac arrest. The coronary angiogram with intravascular imaging was performed and showed a mid-left anterior descending artery atherosclerotic cap rupture with thrombus burden treated with drug-eluting stent (DES) implantation. During the hospitalisation in the intensive care unit, the patient experienced recurrent ventricular fibrillations and asystole with transient ST-segment elevation in the inferior leads with normal coronary angiography. A methylergonovine provocative test was therefore performed and showed an occlusive right coronary artery (RCA) spasm...

OBJECTIVE: Treatment: protocols for cardiac arrest rely upon rhythm analyses performed at two-minute intervals, neglecting possible rhythm changes during the intervening period of CPR. Our objective was to describe rhythm profiles (patterns of rhythm transitions during two-minute CPR cycles) following attempted defibrillation and to assess their relationship to survival. METHODS: The study included out-of-hospital cardiac arrest cases presenting with ventricular fibrillation from 2011-2015...

Sudden death is one of the more frequent causes of death for hemodialysis patients, but the underlying mechanisms, contribution of arrhythmia, and associations with serum chemistries or the dialysis procedure are incompletely understood. To study this, implantable loop recorders were utilized for continuous cardiac rhythm monitoring to detect clinically significant arrhythmias including sustained ventricular tachycardia, bradycardia, asystole, or symptomatic arrhythmias in hemodialysis patients over six months...

The aim of the present experiment was to investigate the possible antiarrhythmic effects of dalfampridine in ouabain-induced arrhythmia in rats. Twenty-four male rats including the control and dalfampridine-incubated (100 µM to 10 mM) ouabain-stimulated (40 µM) groups were used. After induction of anesthesia, the atria were isolated and the time of onset of arrhythmia and asystole were recorded. The contractile force of atria was also measured. Dalfampridine at concentration of 1 mM significantly postponed the onset of arrhythmia and asystole compared to control group (p ≤ ...

BACKGROUND: Propafenone is a sodium-channel blocker, class IC antiarrhythmic drug, frequently used to manage supraventricular dysrhythmias, especially atrial fibrillation. We report a self mono-intoxication with propafenone. CASE REPORT: A 68-year-old woman presented with a decreased level of consciousness, hypotension, and electrocardiogram showing QRS widening with atrial asystole and extreme bradycardia < 20 beats/min. After initial stabilization with transcutaneous pacing, laboratory findings detected normal electrolyte ranges and metabolic acidosis, and her medical history revealed availability of propafenone due to paroxysmal atrial fibrillation and depressive syndrome, which led to the suspicion of intoxication...

BACKGROUND: Acute kidney injury (AKI) is a common complication after liver transplantation and more frequently observed when high-risk grafts, such as DCD grafts are used. Our aim was to investigate the impact of the ischemia periods on development of AKI in DCD liver transplantation. METHODS: We performed a 2-center retrospective study with 368 DCD graft-recipients. Donor warm ischemia time (DWIT) was divided into agonal phase (withdrawal of life-support - cardiac arrest) and asystolic phase (cardiac arrest - start cold perfusion)...

Transient anoxic seizure upon application of pressure on a giant pseudomeningocele has never been reported in the literature; such abrupt changes in intracranial pressure due to large volume of cerebrospinal fluid (CSF) translocation, if left untreated may lead to permanent cerebral hypoxic injury and death. Here we describe a case of a 26-year-old woman who had undergone lumbar disc surgery in another unit few months ago and developed a large lump around her back. Any pressure on the lump resulted in headaches and at times episodes of seizures...

Cannabinoids, the bioactive components of marijuana, have adverse cardiovascular consequences, including symptomatic sinus bradycardia, sinus arrest and ventricular asystole. Physicians should be aware of these deleterious consequences which can appear in otherwise healthy persons who are chronic marijuana users.

BACKGROUND: Gamma-aminobutyric acid-B receptor autoantibodies are becoming an increasingly recognized contributor to the spectrum of autoimmune limbic encephalitis. They are classically associated with seizures and behavioral disturbance, and may coexist with other autoantibodies. Many are paraneoplastic, most commonly associated with small cell lung cancer. Until now there have been no reports of cardiac dysrhythmias in these patients. CASE PRESENTATION: A 65-year-old Caucasian man presented with multiple seizures, dysarthria and behavioral disturbance of unclear etiology, with associated asystolic cardiac arrest...

Background -Prior studies have reported higher in-hospital survival with prompt defibrillation and epinephrine treatment in patients suffering in-hospital cardiac arrest (IHCA). Whether this survival benefit persists after discharge is unknown. Methods -We linked data from a national IHCA registry with Medicare files and identified 36,961 patients aged ≥65 years with an IHCA at 517 hospitals between 2000 and 2011. Patients with IHCA due to pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF) were stratified by prompt (≤2 min) vs...
