INTRODUCTION Cardiovascular disease (CVD) can be detected and quantified by analysis of the electrocardiogram (ECG); however the effects of smoking and smoking cessation on the ECG have not been characterized. METHODS Standard 12-lead ECGs were performed at baseline and 3 years after subjects enrolled in a prospective, randomized, placebo-controlled clinical trial of smoking cessation pharmac...

Cardiovascular diseases (CVDs) are a leading cause of death worldwide. Early detection and diagnosis these can greatly reduce complications improve outcomes for high-risk individuals. One method detecting CVDs is through the use electrocardiogram (ECG) monitoring systems, which various technologies such as Internet Things (IoT), mobile applications, wireless sensor networks (WSN), wearable devi...

BACKGROUND Brugada syndrome (BrS) is characterized by the presence of coved ST-segment elevations in the right precordial leads (so-called type I ECG) and additional clinical features. Caused by cardiac ion channel gene mutations, BrS may be associated with ventricular and atrial conduction disturbances as well as ventricular fibrillation. Recent studies have discussed whether BrS is merely a p...

OBJECTIVE To obtain accurate estimates of the prevalence of ECG abnormalities in the general population and to describe them in relation to age, sex, and some lifestyle related factors. DESIGN The results were obtained from the records of 47 358 men and women participating in four large Belgian epidemiological studies during the past 30 years. All tracings were read and coded by two trained c...

BACKGROUND Left-ventricular hypertrophy (LVH) is a recognized risk factor for myocardial infarction (MI). However, detection of MI by standard electrocardiographic (ECG) criteria may be hampered in patients with LVH. In this setting of hypertensive LVH, the accuracy of two-dimensional (2D) echocardiography in detecting incident MI is unknown. Thus, we compared the accuracy of 2D echocardiograph...

The exact prevalence and nature of cardiac involvement in facioscapulohumeral muscular dystrophy (FSHD) is unknown. Nevertheless, the current opinion is that symptomatic cardiac disease is rare. We performed a cardiac screening [electrocardiogram (ECG) and echocardiography in the event of ECG abnormalities] in 75 genetically confirmed, ambulant FSHD patients without cardiac symptoms, with an ei...

The aim of this retrospective observational case series was to determine electrocardiographic (ECG) manifestations in patients poisoned with methanol and see whether they could predict mortality. We also wanted to see whether there was an association between ECG changes and time elapsed between ingestion and treatment, age, sex, seizure, coma (Glasgow Coma Scale ≤8), arterial blood gas (ABG) pa...

OBJECTIVE To document the prevalence of ECG abnormalities in young healthy smokers and compare ECG changes in smokers, young healthy non-smokers and amongst smokers with different pack years. METHODS This was a prospective case-control study consisting of 200 young healthy male and female individuals, 150 smokers and 50 non-smokers between ages 25-40 years, further categorized and compared ac...
