Type 1 myotonic dystrophy (DM1) is a hereditary neuromuscular disease affecting multiple organs in human adults. Here we report a 42-year-old man diagnosed with DM1. Having a history of progressive muscular weakness and gradual loss of visual acuity, he was referred to us by his ophthalmologist for risk assessment of undergoing cataract surgery. Cardiology workup revealed type 1 Brugada ECG pattern, positive late potentials and inducible ventricular fibrillation in an electrophysiology study. Literature review revealed that those ECG changes may be observed in DM1, suggesting that DM1 and Brugada syndrome may share a common pathophysiologic pathway...

BACKGROUND: Brugada syndrome is an inherited arrhythmogenic disease that may cause sudden cardiac death due to ventricular fibrillation in young adults. Brugada syndrome caused by propafenone intoxication has been noted rarely in the literature. We reported a rare case, Brugada-phenocopy due to propafenone intoxication and its treatment. CASE REPORT: A fifteen-year-old girl having a seizure was brought to the emergency room. She took 1.5 g propafenone (Rythmol, Abbott, Chicago, IL, USA) for suicidal intention...

Aims: Risk stratification in Brugada Syndrome (BS) remains challenging. Arrhythmic events can occur life-long and studies with long follow-ups are sparse. The aim of our study was to investigate long-term prognosis and risk stratification of BS patients. Methods and results: A single centre consecutive cohort of 400 BS patients was included and analysed. Mean age was 41.1 years, 78 patients (19.5%) had a spontaneous type I electrocardiogram (ECG). Clinical presentation was aborted sudden cardiac death (SCD) in 20 patients (5...

Non-invasive risk stratification for ventricular fibrillation (VF) in Brugada syndrome (BrS) has not been fully evaluated. The aim of this study was to assess the utility of signal-averaged Holter electrocardiogram (Holter SAECG) and 12-lead Holter electrocardiogram (Holter ECG) after a pilsicainide provocation test for non-invasive risk stratification in BrS. We enrolled 30 consecutive patients with BrS [divided into 2 groups: the VF group, those with a previous history of VF (n = 10); and the non-VF group, those without a history of VF (n = 20)] and 10 control subjects without type 1 ECG...

The cardiac channelopathies are a group of diseases with (disease-) specific electrocardiographic (ECG) characteristics and a disease-specific risk of sudden cardiac death (SCD). This group includes the Long QT Syndromes (LQTS), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), Brugada Syndrome (BrS), Short QT Syndromes (SQTS), and Early Repolarization Syndrome (ERS). In the past 2 decades the genetic basis for these disease entities has largely been unraveled and that, together with the identification of the genetic basis of the cardiomyopathies, has paved the way for the complete new field of Cardiogenetics...

Background -The genotype-phenotype correlation of SCN5A mutations as a predictor of cardiac events in Brugada syndrome remains controversial. We aimed to establish a registry limited to probands, with a long follow-up period, so that the genotype-phenotype correlation of SCN5A mutations in Brugada syndrome can be examined without patient selection bias. Methods -This multicenter registry enrolled 415 probands (n=403; men, 97%; age, 46±14 years) diagnosed with Brugada syndrome whose SCN5A gene was analyzed for mutations...

Aims: Subcutaneous implantable cardioverter-defibrillator (S-ICD) can avoid important complications associated with transvenous leads in patients with inherited primary arrhythmia syndromes, who do not need pacing therapy. Few data are available on the percentage of patients with inherited arrhythmia syndromes eligible for S-ICD implantation. Aim of this study was to analyse the eligibility for S-ICD in a series of patients with Brugada syndrome (BrS), and to compare it with patients with other channelopathies...

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)...

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...
