BACKGROUND: Loperamide has been increasing in popularity recently for its effects separate from treatment of diarrhea. In large doses or in combination with other agents, it can lead to desirable effects in the central nervous system. However, cardiotoxicity has been reported with its abuse. CASE REPORT: A 49-year-old male who had been chronically abusing loperamide was found to have Brugada-like changes on his electrocardiogram (ECG). He had no other clinical symptoms associated with Brugada syndrome and did not have similar findings on previous ECGs...

Brugada phenocopies (BrPs) are clinical entities that differ in etiology from true congenital Brugada syndrome but have identical electrocardiographic (ECG) patterns. Hyperkalemia is known to be one of the causes of BrP. The aim of this study was to determine the clinical characteristics and evolution of hyperkalemia-induced BrP. Data from 27 cases of hyperkalemia-induced BrP were collected from the International Registry at www.brugadaphenocopy.com. Data were extracted from publications. Of the 27 patients included in the analysis, 18 (67%) were male; mean age was 53 ± 15 years (range 31 to 89)...

Background: Brugada syndrome (BrS) is an inherited channelopathy, which is associated with sudden cardiac death due to rapid polymorphic VT or VF. There is no definite consensus regarding the management of asymptomatic patients. Some experts advocate close follow-up; others propose the programmed stimulation for risk stratification. We aimed to evaluate the benefit of complete atrial and ventricular stimulation in patients with BrS and palpitation. Case Presentation: A 30-year-old man was admitted to our hospital because of a family history of sudden cardiac death (SCD) at age less than 45 years...

RATIONALE: Brugada syndrome (BrS) is a cardiac ion channel disease that is caused by an autosomal dominant genetic abnormality. A ventricular septal defect is a common congenital heart disease, in which genetic defects play a significant role. PATIENT CONCERNS: We report an extremely rare case of a 42-year-old male with congenital heart disease, who suffered recurrent syncope and gastrointestinal bleeding. His electrocardiogram showed an unusual right bundle branch block-like pattern and ST-segment elevation in leads V1-V3...

Objectives: According to recent publications, some patients with spinal and bulbar muscular atrophy (BSMA) develop cardiac disease, manifesting as ST-segment abnormalities, Brugada-syndrome, dilative cardiomyopathy, or sudden cardiac death. Here we present neurological and cardiac data of a BSMA patient who was followed up for 10 y. Case report: In a male patient aged 47 y, BSMA was diagnosed at age 37 y upon the typical clinical presentation (postural tremor since age 12 y, dysarthria since age 15 y, muscle cramps since age 29 y, general myalgias since age 32 y, general fasciculations since age 34 y, myoclonic jerks, easy fatigability, dyspnea upon exercise since age 36 y) and a CAG-repeat expansion of 47 ± 1 repeats in the androgen-receptor gene detected at age 37 y...

BACKGROUND: Young patients presenting with symptomatic Brugada syndrome have very high risks for ventricular arrhythmias and should be carefully considered for implantable cardioverter-defibrillator (ICD) placement. However, this therapy is associated with high rates of inappropriate shocks and device-related complications. OBJECTIVES: This study investigated clinical features, management, and long-term follow-up of young patients with Brugada syndrome and ICD. METHODS: Patients diagnosed with Brugada syndrome, who underwent implantation of an ICD at an age of ≤20 years, were studied...

OBJECTIVES: The electrocardiogram (ECG) of patients with BrS in sinus rhythm might reflect intrinsic atrial electrical abnormalities independent from any previous atrial fibrillation (AF). Aim of this study is to investigate the presence of P-wave abnormalities in patients with BrS and no history of AF, and to compare them with those displayed by patients with documented paroxysmal AF and by healthy subjects. METHODS: Continuous 5-min 16-lead ECG recordings in sinus rhythm were obtained from 72 participants: 32 patients with a type 1 Brugada ECG, 20 patients with a history of paroxysmal AF and 20 age-matched healthy subjects...

We describe the use of extracorporeal cardiopulmonary resuscitation (E-CPR) to transiently stabilize a 3-month-old patient who presented with ventricular tachyarrhythmias leading to spontaneous cardiac arrest. The patient required 4 days of extracorporeal life support (ECLS) where he was diagnosed with probable Brugada syndrome (BS). The patient was discharged home in stable condition after implantable cardioverter defibrillator placement. This case highlights the importance of early transfer to extracorporeal membrane oxygenation (ECMO) center in the setting of unexplained cardiac arrhythmia in a pediatric patient...

BACKGROUND Brugada pattern on electrocardiogram (ECG) is seen when there are at least 2 mm J-point elevation and 1 mm ST-segment elevation in two or more of the right precordial leads, with right bundle-branch block (RBBB)-like morphology. Elevation of a coved-type shape in leads V1 and V2 is consistent with type I Brugada pattern, whereas elevation of a saddle-back configuration distinguishes type II Brugada. If accompanied by life-threatening arrhythmias or sudden cardiac death, Brugada syndrome (BrS) is diagnosed...

BACKGROUND AND OBJECTIVE: The occurrence of cardiac electrical abnormalities such as repolarization disorders in patients with epilepsy was previously documented and may, in part, clarify the mechanism of sudden unexpected death in those patients. The aim of this study was to investigate the frequency of cardiac repolarization disorders among patients with epilepsy and whether specific demographic- or disease-related features were associated with their occurrence. SUBJECTS AND METHODS: This cross-sectional study was carried out on 1000 subjects with epilepsy who were compared with age- and sex-matched 2500 subjects without epilepsy...

Nikhil Mehta, Robert Vannozzi
Lithium has been used for the treatment of bipolar disorder for more than 6 decades. Reports of cardiac side effects resulting in both benign electrocardiographic (ECG) changes and near fatal arrhythmias have been reported in the literature. A systematic literature search was conducted on 2 electronic databases-PubMed and Medline-for the time period between January 1970 and March 2016 using the key word "lithium," along with "electrocardiography" or "ECG." All articles and their references were then screened by title for relevance by 2 authors and a librarian...

A Brugada phenocopy has been defined as a clinical situation that presents with an abnormal electrocardiogram identical to any of the electrocardiographic patterns found in Brugada syndrome in the absence of the characteristic congenital genetic abnormalities. The first confirmed case of type 1 Brugada phenocopy associated with severe left pneumothorax is presented. A provocative test with ajmaline, which proved to be negative, was performed to confirm the diagnosis. The presence of ST-segment elevation in the context of pneumothorax is most infrequent...

REVIEW
Gonçalo Tomé, João Freitas
Brugada syndrome is an inherited cardiac condition with the potential for development of life-threatening arrhythmias in relatively young individuals without significant structural cardiac abnormalities. The condition is characterized by a distinct coved-type ST segment elevation in the right precordial leads (V1-V3). This hallmark pattern (type 1) is often dynamic and sometimes concealed, and may be unmasked in certain conditions or under the effect of certain agents, which include variation of sympathovagal balance, hormones, metabolic factors and drugs...

#17
Samuel Chauveau, Olivier Le Vavasseur, Philippe Chevalier
A negative flecainide challenge does not rule out Brugada syndrome even in the presence of nonfatal cardiac arrest as the first manifestation of the disease. This should prompt clinicians to ensure long-term ECG follow-up and consider repeating a drug test with another sodium channel blocker.

OBJECTIVE: Typical Brugada ECG pattern is the keystone in the diagnosis of Brugada syndrome. However, the exact prevalence remains unclear, especially in Asia. The present study was designed to systematically evaluate the prevalence of spontaneous Brugada ECG pattern recorded at standard leads. METHODS: We searched the Medline, Embase and Chinese National Knowledge Infrastructure (CNKI) for studies of the prevalence of Brugada ECG pattern, published between Jan 1, 2003, and September 1, 2016...

BACKGROUND: A common SCN5A polymorphism H558R (c.1673 A > G, rs1805124) improves sodium channel activity in mutated channels and known to be a genetic modifier of Brugada syndrome patients (BrS). We investigated clinical manifestations and underlying mechanisms of H558R in BrS. METHODS AND RESULTS: We genotyped H558R in 100 BrS (mean age 45 ± 14 years; 91 men) and 1875 controls (mean age 54 ± 18 years; 1546 men). We compared clinical parameters in BrS with and without H558R (H558R+ vs...
