Brugada syndrome (BrS) is an inherited disorder of cardiac ion channels characterized by peculiar ECG findings predisposing individuals to ventricular arrhythmias, syncope, and sudden cardiac death (SCD). Various electrolyte disturbances and ion channels blocking drugs could also provoke BrS ECG findings without genetic BrS. Clinical differentiation and recognition are essential for guiding the legitimate action. Hyperkalemia is well known to cause a wide variety of ECG manifestations. Severe hyperkalemia can even cause life threatening ventricular arrhythmias and cardiac conduction abnormalities...

A novel cardiac health device technique development for reliable, non-invasive and cost-effective heart screening in preventive cardiovascular healthcare is presented. In particular, identification of apparently healthy individuals involved in sports activities (particularly in the young, age <; 35 years) who may be at-risk of sudden-cardiac-death (SCD) is mainly focused here. Nevertheless, the same device technique may be prospectively extended for detecting cardiovascular abnormalities in children and adolescents with type1-diabetes, and also in detecting patients with Brugada syndrome...

Pectus excavatum (PE), the most common skeletal anomaly of chest wall, sometimes requires a surgical correction but recurrent PE is not uncommon. PE usually has a benign course; however, this chest deformity may be associated with symptomatic tachyarrhythmias due to mechanical compression. We report a case of a patient with recurrent PE after surgical correction presenting with palpitation and electrocardiogram (ECG) showing ST-segment elevation on the right precordial leads, which could be mistaken for a Brugada syndrome (BrS)...

INTRODUCTION: Risk stratification of asymptomatic patients with a Brugada type 1 ECG pattern remains an unresolved clinical conundrum. In contrast to provocative pharmacological testing in Brugada syndrome, there is limited data on the role of exercise stress testing as a risk stratification modality. The objective of this study was to evaluate the utility of exercise testing in asymptomatic patients with type 1 Brugada pattern to prognosticate major arrhythmic events(MAE) during follow-up...

BACKGROUND: The second-generation cryoballoon (cryoballoon Advance; CB-A) offers excellent outcomes on the mid-term follow-up. To the best of our knowledge, little is known regarding the long-term outcome after CB-A ablation for paroxysmal atrial fibrillation (AF). OBJECTIVE: The aim of the study was to evaluate the freedom from recurrence of AF during a 3-year follow-up period, among consecutive patients having undergone pulmonary vein isolation (PVI) with the CB-A for paroxysmal AF (PAF)...

This study analyzes the natural history of a large cohort of probands with Brugada syndrome (BrS) to assess the predictive value of different clinical and electrocardiographic parameters for the development of ventricular fibrillation (VF) or sudden cardiac death (SCD) during a long-term follow-up. Baseline characteristics of 289 consecutive probands (203 men; mean age 45 ± 16 years) with a Brugada type 1 electrocardiogram were analyzed. After a mean follow-up of 10.1 ± 4.6 years, 29 malignant arrhythmias occurred...

This short communication accompanies my presentation at the International Congress on Sudden Cardiac Death held in Prague, March 30-April 1, 2017. It summarizes briefly studies of the cardiac electrophysiological substrate in patients with hereditary arrhythmogenic syndromes - the Long QT and Brugada syndromes - conducted noninvasively, in situ, using Electrocardiographic Imaging (ECGI). The same noninvasive approach was used to map the electrophysiological substrate of a post-infarction myocardial scar and to relate this substrate to the pattern of activation during reentrant ventricular tachycardia...

The Brugada syndrome is a rare condition associated with increased risk of ventricular tachyarrhythmias and sudden cardiac death (SCD). The Brugada pattern on electrocardiogram (EKG) is known to be revealed by several precipitants including febrile illnesses. The appearance of a Brugada pattern on EKG with fever may indicate an elevated risk of arrhythmia or sudden cardiac death. We report a case in which the electrocardiographic abnormality of Brugada pattern induced by sepsis was initially misinterpreted as a ST-segment elevation myocardial infarction (STEMI)...

Coved-type ST-segment elevation in the right precordial leads are the characteristics of Brugada syndrome, an inherited arrhythmogenic ion channel disease, which could lead to ventricular arrhythmia and sudden death. Hypokalemia alone may induce Type 1 Brugada pattern electrocardiogram (EKG), and the association has rarely been reported. We describe a patient with hypokalemia 2.9 mmol/L and the appearance of new right bundle branch block pattern with coved ST-segment elevations with inverted T wave in leads V1-V2...

Background: Brugada syndrome (BrS) is characterized by J-point or ST-segment elevation on electrocardiograms (ECGs) and increased risk of ventricular fibrillation (VF). In BrS, epicardial depolarization abnormality with delayed potential on the right ventricular outflow tract is reportedly the predominant mechanism underlying VF. Yet VF occurrence is also associated with early repolarization (ER) pattern in the inferolateral ECG leads, which may represent the inferior and/or left lateral ventricular myocardium...

Brugada syndrome is a rare inherited arrhythmia syndrome leading to an increased risk of sudden cardiac death, despite a structurally normal heart. Diagnosis is based on a specific electrocardiogram pattern, observed either spontaneously or during a sodium channel blocker test. Among affected patients, risk stratification remains a challenge, despite recent insights from large population cohorts. As implantable cardiac defibrillators - the main therapy in Brugada syndrome - are associated with a high rate of complications in this population, the main challenge is risk stratification of patients with Brugada syndrome...

We report the case of a 2-month old infant who experienced recurrent sustained ventricular tachycardia (VT) in a structurally normal heart. Resting electrocardiogram (ECG) showed wide QRS with a complete right bundle branch bloc (RBBB) morphology. There was no family history of syncope or sudden death, but the ECGs of the father and the brother showed incomplete RBBB with negative T waves on V1 lead. This case seems to fit well with the newly defined entity of Brugada-like syndrome with a highly suspected genetic underlying disposition...

Brugada syndrome is an inherited disorder that can present with syncope, cardiac arrest, or sudden cardiac death. Multiple genetic mutations have been described that cause this disease. We present a 56-year-old man who sustained an out-of-hospital cardiac arrest, was resuscitated, and was found to have typical features of the Brugada criteria on the electrocardiogram. Genetic testing was positive for a heterozygous mutation in the sodium voltage-gated channel alpha subunit 5 (SCN5A) gene with a p. Leu227Pro (L227P) variant located on exon 6...

BACKGROUND: Brugada-type ECG (Br-ECG) is occasionally observed during acute myocardial ischemia of the right ventricular outflow tract (RVOT). No studies have explored, however, the association of ventricular tachyarrhythmia and development of Br-ECG due to acute ischemia of the RVOT.Methods and Results:The study included 13 consecutive patients with acute ischemia of the RVOT during coronary catheterization. Patients were divided into 2 groups: those with Br-ECG (group B) and those without (group N)...

BACKGROUND: The role of J-waves in the pathogenesis of ventricular fibrillation (VF) occurring in structurally normal hearts is important. METHODS: We evaluated 127 patients who received an implantable cardioverter-defibrillator (ICD) for Brugada syndrome (BS, n = 53), early repolarization syndrome (ERS, n = 24), and patients with unknown or deferred diagnosis (n = 50). Electrocardiography (ECG), clinical characteristics, and ICD data were analyzed. RESULTS: J-waves were found in 27/50 patients with VF of unknown/deferred diagnosis...

BACKGROUND: Sport is very important for health promotion and conservation. Active lifestyle and regular exercise reduce cardiovascular disease incidence. The Italian Ministry of Health issued the Law Decree no. 243 (10/18/2014) concerning "guidelines for certification about non-competitive sports" to promote safety in sports. This regulation defines the activities for which a certificate is required, the professional actors involved and the clinical exams to be performed according to the patient's health status...
