BACKGROUND Endocardial voltage mapping (EVM) identifies low-voltage right ventricular (RV) areas, which may represent the electroanatomic scar substrate of life-threatening tachyarrhythmias. We prospectively assessed the prognostic value of EVM in a consecutive series of patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D). (More)
In his quest to comprehend his existence, Man has long been exploring his outer world (macro-cosmos), as well as his inner world (micro-cosmos). In modern times, monmental advances in the fields of physics, chemistry, and other natural sciences have reflected on how we understand the anatomy and physiology of the human body and circulation. Yet, humanity(More)
Takotsubo cardiomyopathy (TTC) is a transient left ventricular (LV) dysfunction due to akinesia of the LV mid-apical segments ('apical ballooning') in the absence of critical coronary stenoses which can be complicated in the acute phase by heart failure, mitral regurgitation, life-threatening ventricular arrhythmias, or apical LV thrombosis. The syndrome is(More)
Electrocardiographic (ECG) pre-participation screening can prevent sudden cardiac death in the athletes by early diagnosis and disqualification of affected individuals. Interpretation of the athlete's ECG should be based on specific criteria, because ECG changes that would be considered abnormal in the untrained population may develop in trained athletes as(More)
INTRODUCTION The extent of right ventricular (RV) electroanatomic scar (EAS) detected by endocardial voltage mapping (EVM) is a powerful invasive predictor of arrhythmic outcome in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Electrocardiogram (ECG) and signal-averaged ECG are noninvasive tools of established clinical value for the(More)
BACKGROUND There are few data on heart failure (HF) patients from Africa, Asia, the Middle East and South America. METHODS INTER-CHF is a prospective study that enrolled HF patients in 108 centers in 16 countries from 2012 to 2014. Consecutive ambulatory or hospitalized adult patients with HF were enrolled. Baseline data were recorded on(More)
Takotsubo cardiomyopathy (TTC) is a transient left ventricular dysfunction due to akinesia of the left-ventricular (LV) mid-apical segments (apical ballooning), which can cause severe reduction in LV systolic function. The typical clinical picture of TTC include chest pain, electrocardiographic changes consisting of mild ST-segment elevation followed by(More)
BACKGROUND Although heart failure (HF) has been referred to as a global epidemic, most HF information comes from high-income countries, with little information about low-income countries (LIC) and middle-income countries (MIC) in Africa, Asia, the Middle East, and South America, which make up the majority of the world's population. METHODS The(More)
Negative T waves (NTWs) in right precordial leads (V₁ to V₃) may be observed on the electrocardiogram (ECG) of healthy subjects but can also represent the hallmark of an underlying arrhythmogenic right ventricular cardiomyopathy (ARVC). It has been a consistent observation that NTWs usually become upright with exercise in healthy subjects without underlying(More)
BACKGROUND Most data on mortality and prognostic factors in patients with heart failure come from North America and Europe, with little information from other regions. Here, in the International Congestive Heart Failure (INTER-CHF) study, we aimed to measure mortality at 1 year in patients with heart failure in Africa, China, India, the Middle East,(More)
