Objectives: Electrocardiogram (ECG) data are important for the study of cardiovascular disease and adverse drug reactions. Although the development of analytical techniques such as machine learning has improved our ability to extract useful information from ECGs, there is a lack of easily available ECG data for research purposes. We previously published an article on a database of ECG parameters and related clinical data (ECG-ViEW), which we have now updated with additional 12-lead waveform information...

Sarcoidosis is a multisystem granulomatous disease predominantly affecting the lungs, with increased risk of cardiovascular disease, pulmonary hypertension and cardiac sarcoidosis (CS), the latter due to direct granuloma infiltration. Sarcoidosis is often managed by chest physicians who need to understand the diagnostic pathways and initial management plans for patients with cardiac involvement. Areas covered: The most serious consequence of CS is sudden cardiac death due to ventricular tachyarrhythmias or complete atrioventricular block...

Objectives: Cardiovascular diseaseand heart failure (CHF) are leading causes of death in systemic lupus erythematosus (SLE). The underlying mechanisms for increased CHF in SLE are unclear but myocardial inflammation and lupus myocarditis (LM) may play a role. We propose that 18 F-fluorodeoxyglucose-positron emission tomography (18 F-FDG-PET)/CT can help diagnose LM. Methods: This report describes eight patients with presumed LM; five patients were evaluated due to active cardiorespiratory symptoms and three patients were participating in a pilot study to determine the prevalence of subclinical myocarditis in SLE...

Reflex anoxic seizures (RAS) present with a transient loss of consciousness and are triggered by an unexpected stimuli. These are paroxysmal, short-lived episodes of pronounced bradycardia or transient asystole; the episodes are self-limiting, lasting between 15 seconds and 1 minute. RAS are an important differential diagnosis of transient loss of consciousness but they are commonly misdiagnosed as epileptic events. An accurate and focused history is key to the diagnosis. They are mostly managed by performing an ECG to rule out other causes of arrhythmia, with subsequent explanation of the condition and reassurance given to parents...

Methadone is known to be a risk factor for sudden death by enlarging ECG QT corrected (QTc) interval. For other medical conditions, QTc lengthening has been described as the result of interactions between pharmacological treatments and genetic factors. Former heroin dependent subjects under methadone maintenance treatment in remission for at last 3 months were recruited. We studied the association between QTc length (Bazett formula) and 126 SNPs located on 5 genes (KCNE1, KCNQ1, KCNH2, NOS1AP and SCN5A) previously associated with drug-induced QT prolongation...

INTRODUCTION: Rheumatic heart disease (RHD) is the commonest cause of valvular heart disease and a common cause of heart failure in sub-Saharan Africa (SSA). Atrial fibrillation (AF) complicates RHD, precipitates and worsens heart failure and cause unfavourable outcomes. We set out to describe the prevalence, clinical characteristics and outcomes of valvular atrial fibrillation in a cohort of African patients with acute heart failure (AHF). METHODS: The sub-Saharan Africa Survey of Heart Failure (THESUS-HF) was a prospective, observational survey of AHF in nine countries...

BACKGROUND: Investigating regarding a predicted risk score of incident atrial fibrillation (AF) for an Asian general population has not been enough. Whether addition of electrocardiogram (ECG) variables to risk factors improves prediction of incident AF is unclear in a context that ECGs are extensively used at medical check-ups and outpatient clinics in Japan. METHODS: Participants undergoing periodic health check-ups during 2008-2014 followed-up by December 2015 including 96,841 (65...

According to the present European Society of Cardiology's guidelines for atrial fibrillation (AF), the definition of AF contains a 30-second time criterion, based on consensus. The aim of this cohort study is to evaluate whether very short-lasting episodes of AF, micro-AF, are risk factors for developing AF and to compare AF detection between continuous and intermittent ECG recordings applied in parallel. All participants, n = 102, were identified from the STROKESTOP study, a Swedish mass-screening study for AF...

Aripiprazole is an atypical antipsychotic drug with a polypharmacological mechanism of action and a favorable tolerability profile. Its major indications are schizophrenia and mania in adults and adolescents. Here we present the case of a 43-year-old Caucasian man with schizophrenia who developed atrial fibrillation (AF) after starting aripiprazole treatment. Prior to this treatment, he had never received any antipsychotic drugs. On admission to our inpatient unit, he showed severe psychotic symptoms and was started on aripiprazole with a rapid titration regimen (15 mg on the first day and then 15 mg twice daily thereafter) in combination with lorazepam (2...

Orthodromic atrioventricular reentrant tachycardia (AVRT) is the second-most-common form of supraventricular tachycardia (SVT) and is inducible in approximately 55% of individuals with Wolff Parkinson White (WPW) syndrome. Antidromic AVRT, where the accessory atrioventricular connection is used as the antegrade limb and the atrioventricular node serves as the retrograde limb of the circuit, has been clinically documented in less than 5% of patients with WPW syndrome and may be induced in less than 10% of these WPW cases in the electrophysiology laboratory...

Chest pain and shortness of breath are chief complaints frequently evaluated in the emergency department. ACS, pulmonary embolism, and disorders involving the lung parenchyma are some of the disease processes commonly screened for. Occasionally, patients presenting with histories and clinical exams consistent with these common illnesses may end up having more rare pathology. We present the case of a young patient who presented with chest pain and dyspnea with ECG changes and history concerning for pulmonary embolism who was ultimately diagnosed with idiopathic primary pulmonary hypertension...

BACKGROUND: Epileptic seizures can lead to cardiac arrhythmias. The arrhythmias may be in the form of tachycardia, bradycardia or asystole. Ictal bradycardia and asystole can lead to sudden unexpected death. CASE PRESENTATION: A case report of a 40-year-old male with complex partial temporal lobe epilepsy. He has coincident attacks of fall and pallor. The patient underwent simultaneous electrocardiogram (ECG) and video electroencephalogram (EEG) monitoring. The slow activity in EEG coincide with the appearance of bradycardia in ECG then cardiac asystole which clinically correspond to the patient syncope...

We present a case of a 59-year-old man with acute abdominal pain and progressive shortness of breath. A focused assessment with sonography for trauma scan showed free fluid in the hepatorenal recess and in the recto-uterine recess. Later, due to clinical deterioration and the differential possibility of a pulmonary embolism or aortic dissection, a CT scan was performed which revealed large pericardial effusion. This, together with a dilated vena cava inferior and portal system, raised the suspicion of cardiac tamponade...

INTRODUCTION: Pheochromocytomas are infrequent tumors arised from the chromaphine cells of the adrenal sympathetic system. The excess of circulating catecholamines may lead to different cardiovascular disorders from silent alterations of the myocardial conduction to different forms of cardiomyopathy. The onset as cardiogenic shock is exceptional. PRESENTATION OF CASE: A 35-year-old male, with a known history of acute myopericarditis of unknown origin which debuted as acute pulmonary edema, was admitted with dyspnea in the context of a new heart failure episode with pulmonary edema...

Introduction: The Revised Trauma Score (RTS) accurately identifies trauma patients at high risk of adverse events or death. Less is known about its usefulness in the general population and non-trauma recipients of Helicopter Emergency Medical Service (HEMS). The RTS is a simple tool and omits a lot of other data obtained during clinical evaluation. The aim was to assess the role of the RTS to identify patients at risk of major complications (death, cardiopulmonary resuscitation, defibrillation, intubation) in the general population of HEMS patients...

INTRODUCTION: Mutations within SCN5A are found in a significant proportion (15-30%) of Brugada syndrome (BrS) cases and impair sodium transport across excitable cardiac cells that mediate ventricular contractions. Genetic testing offers a means to clinically assess and manage affected individuals and their family members. METHODS AND RESULTS: The proband at age 44 years old exhibited a syncopal event during exercise, and presented later with a spontaneous type-I BrS pattern on 12‑lead resting electrocardiogram (ECG)...
