INTRODUCTION: Sudden cardiac arrest (SCA) in athletes is an unexpected life-threatening event, which is often not recognised early and cardiopulmonary resuscitation (CPR) is not always initiated immediately. We describe key features to rapidly recognise non-traumatic SCA in athletes during sports activity. METHODS: We reviewed videos and images of athletes suffering from non-traumatic SCA during sports activity. We searched Google images, Google videos and YouTube...

A 54-year-old man, ex smoker with high blood pressure and a history of possible Wolff-Parkinson-White syndrome was admitted for presenting an episode suggestive of acute coronary syndrome with immediate syncope and left bundle branch block, while performing physical activity. Angioplasty and a drug-eluting stent were performed in the left circumflex artery. Subsequently, Doppler echocardiography disclosed an image suggestive of a subaortic membrane. Given these findings, the patient underwent a 3D transesophageal echocardiogram and a magnetic resonance study, which confirmed the diagnosis of a subaortic membrane...

BACKGROUND: Uterine leiomyomas represent the gynecological neoplasm with the highest prevalence worldwide. This apparently benign pathological entity may permeate into the venous system causing the so-called intravenous leiomyomatosis of the uterus (IVL). IVL may seldom extend to large caliber veins and reach the right cardiac chambers or pulmonary arteries and cause signs of right sided congestive heart failure and sudden death. Due to its low incidence, however, IVL with intracardiac extension is often misdiagnosed resulting in deferred treatment...

Orthostatic challenge produced by upright posture may lead to syncope if the cardiovascular system is unable to maintain adequate brain perfusion. This review outlines orthostatic intolerance related to the aging process, long-term bedrest confinement, drugs, and disease. Aging-associated illness or injury due to falls often leads to hospitalization. Older patients spend up to 83% of hospital admission lying in bed and thus the consequences of bedrest confinement such as physiological deconditioning, functional decline, and orthostatic intolerance represent a central challenge in the care of the vulnerable older population...

REVIEW

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy characterized by ventricular arrhythmias and an increased risk of sudden cardiac death. Although structural abnormalities of the right ventricle predominate, it is well recognized that left ventricular involvement is common, particularly in advanced disease, and that left-dominant forms occur. The pathological characteristic of ARVC is myocyte loss with fibrofatty replacement. Since the first detailed clinical description of the disorder in 1982, significant advances have been made in understanding this disease...

INTRODUCTION: There are conflicting data regarding the prognostic value of syncope in patients with acute pulmonary embolism (APE). METHODS: We retrospectively reviewed data of 552 consecutive adults with computed tomography pulmonary angiogram-confirmed APE to determine the correlates and outcome of the occurrence of syncope at the time of presentation. RESULTS: Among 552 subjects with APE (mean age 54years, 47% men), syncope occurred in 12...

Syncope is defined as a sudden transient loss of consciousness (TLOC) with concomitant loss of postural tone followed by spontaneous recovery. It is a subset of a broader class of medical conditions, including postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension, and neurally mediated syncope (NMS), that may result in TLOC. The overlap of these clinical conditions leads to confusion regarding syncope classification that can hinder evaluation strategies, and pose challenges for diagnosis and treatment, particularly in young women...

BACKGROUND: Syncope is an event that causes a transient loss of consciousness (LOC) secondary to global cerebral hypoperfusion. The transient nature of the event can make diagnosis in the emergency department (ED) difficult, as symptoms have often resolved by time of initial presentation. The symptoms and presentation of syncope are similar to many other conditions, which can lead to difficulty in establishing a diagnosis in the ED. OBJECTIVE: This review evaluates patients presenting with a history concerning for possible syncope, mimics of syncope, and approach to managing syncope mimics...

Emergency department (ED) visits for syncope are common. Validation of ED administrative diagnostic coding for syncope is required before these codes can be used for health services research. We performed a retrospective multicentre chart review using a regional ED database in British Columbia. We identified adults who visited 1 of 3 high-volume urban EDs between 2010 and 2015. Cohort 1 included 350 ED visits for patients with a presenting complaint (PC) of syncope/presyncope, a discharge diagnosis (DD) of syncope and collapse, or both...

The generation and propagation of the cardiac impulse is the central function of the cardiac conduction system (CCS). Impulse initiation occurs in nodal tissues that have high levels of automaticity, but slow conduction properties. Rapid impulse propagation is a feature of the ventricular conduction system, which is essential for synchronized contraction of the ventricular chambers. When functioning properly, the CCS produces ~2.4 billion heartbeats during a human lifetime and orchestrates the flow of cardiac impulses, designed to maximize cardiac output...

We report the case of a male patient of 75 years old who presents with abdominal pain, hyporexia, early satiety, general malaise and watery stools, admitted in emergency for an episode of syncope. On physical examination, hepatomegaly of 6cm below the right costal margin was detected. CT scan showed multiple liver metastases. An upper endoscopy found multiple hyperpigmented lesions on the second portion of the duodenum. Histology and immunohistochemistry studies concluded it was duodenal melanoma. Skin and ocular examination did not reveal associated neoplastic lesions...

BACKGROUND: Medical students are taught little or nothing about the medical considerations related to the driving of motor vehicles. Physicians treating patients with cardiovascular disease need to acquire competence in traffic medicine in order to be able to advise them about their fitness to drive. METHODS: We present the current governmental regulations and recommendations concerning fitness to drive in patients with cardiovascular disease. We also review pertinent publications that were retrieved by a selective search in PubMed with the search terms "cardiovascular disease and traffic accidents" and "cardiovascular disease and traffic deaths" for the decade 2007-2016, as well as further publications collected by us individually...

INTRODUCTION: The vagus nerve has sensory and motor function in the larynx, as well as parasympathetic function in the thorax and abdomen. Stimulation of the superior laryngeal nerve can cause reflexive bradycardia. CASE: We describe a case of a 45-year-old man with pre-syncopal symptoms while exercising, and bradycardia found during cardiology workup. Radiography and flexible laryngoscopy showed evidence of a right-sided, vascular laryngeal mass. Exercise testing before and after superior laryngeal nerve block showed reversal of the symptoms with the block...

A young man suffered cardiac arrests with polymorphic ventricular tachycardia (PVT) and ventricular fibrillation (VF) triggered by ventricular premature contractions (PVCs). The arrhythmia was resistant to anti-arrhythmics, so after ICD implantation he underwent successful ablation of the triggering VE beat, which was pace-mapped to the left posterior hemi-fascicle. We review the evidence for the role of the Purkinje network in the initiation and maintenance of PVT and VF, postulating a channelopathy as a possible underlying cause, and provide recommendations for PVC ablation...
