Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a recognised cause of sudden cardiac death during exercise in young athletes. Competitive exercise is also known to accelerate progression of ARVC and exercise restriction is an important part of disease management. Regular endurance training can induce physiological changes detectable on electrocardiography and imaging which may overlap with pathological findings caused by ARVC, thus making differentiation of athlete's heart from ARVC difficult in some cases...

OBJECTIVES: Intense exercise elevates all heart chambers' dimensions, left ventricular mass (LV mass), and left ventricular mass index (LV mass index). The relationship between increased ventricular arrhythmias and sudden cardiac death with LV dilatation and elevated LV mass has been previously demonstrated. We investigated whether sports-related LV dilatation and elevated LV mass and LV mass index cause an increase in ventricular repolarization heterogeneity. PATIENTS AND METHODS: This prospective observational study recruited 565 participants...

BACKGROUND: Exercise mitigates many cardiovascular risk factors associated with atrial fibrillation. Endurance training has been associated with atrial structural changes which can increase the risk for atrial fibrillation. The dose of exercise training required for these changes is uncertain. We sought to evaluate the impact of exercise on left atrial (LA) mechanical and electrical function in healthy, sedentary, middle-aged adults. METHODS: Sixty-one adults (52±5 years) were randomized to either 10 months of high-intensity exercise training or yoga...

Exercising horses uniquely accommodate 7-8-fold increases in heart rate (HR). The present experiments for the first time analysed the related adaptations in action potential (AP) restitution properties recorded by in vivo telemetric electrocardiography from Thoroughbred horses. The horses were subjected to a period of acceleration from walk to canter. The QRS durations, and QT and TQ intervals yielded AP conduction velocities, AP durations (APDs) and diastolic intervals respectively. From these, indices of active, λ = QT/(QRS duration), and resting, λ0 = TQ/(QRS duration), AP wavelengths were calculated...

Blood flow is a clinical metric for monitoring of cardiovascular diseases but current measurements methods are costly or uncomfortable for patients. It was shown that the interaction of the magnetic field (B 0) during MRI and blood flow in the body, through the magnetohydrodynamic (MHD) effect, produce voltages (V MHD) observable through intra-MRI electrocardiography (ECG), which are correlated with regional blood flow. This study shows the reproducibility of V MHD outside the MRI and its application in a portable flow monitoring device...

Sudden cardiac death (SCD) is the leading cause of death during exercise in young athletes. Preparticipation physical examinations were developed to maintain the health and safety of athletes, including the prompt identification of those at risk for SCD. The use of medical history and physical examinations, electrocardiography, and echocardiography, or some combination thereof, is the source of continued debate. This article provides an overview of the etiology of SCD and reviews literature relating to preparticipation echocardiography, with a focus on its evolution, utility, and effectiveness...

Congenital coronary artery abnormalities may cause sudden death, particularly in athletes. Two siblings, aged 10 and 9 years, respectively, were diagnosed with anomalous origin of the right coronary artery on multi-detector computed tomography (MDCT). The right coronary artery arose from the left coronary cusp, and was wedged between the aorta and pulmonary artery. This was also noted on cardiac ultrasonography (UCG), but in general this might not be seen on electrocardiography at rest. Although the surgical indications are unclear in the case of unproven ischemia, early recognition of the condition may reduce risk of the cardiac events during exercise...

BACKGROUND: Most exercise-related cardiac arrests in men aged ≥45 years are due to coronary artery disease (CAD). The current sports medical evaluation (SME) of middle-aged sportsmen includes medical history, physical examination and resting and exercise electrocardiography (ECG). We investigated the added value of low-dose cardiac computed tomography (CCT) - both non-contrast CT for coronary artery calcium scoring (CACS) and contrast-enhanced coronary CT angiography (CCTA) - in order to detect occult CAD in asymptomatic recreational sportsmen aged ≥45 years without known cardiovascular disease...

OBJECTIVES: Although regular physical exercise clearly reduces cardiovascular morbidity risk, long-term endurance sports practice has been recognized as a risk factor for atrial fibrillation (AF). However, the mechanisms how endurance sports can lead to AF are not yet clear. The aim of our present study was to investigate the influence of long-term endurance training on vagal tone, atrial size, and inflammatory profile in professional elite soccer players. METHODS: A total of 25 professional major league soccer players (mean age 24±4 years) and 20 sedentary controls (mean age 26±3 years) were included in the study and consecutively examined...

BACKGROUND: Physiological cardiac adaptation to regular exercise, including biventricular dilation and T-wave inversion (TWI), may create diagnostic overlap with arrhythmogenic right ventricular cardiomyopathy (ARVC). OBJECTIVES: The goal of this study was to assess the accuracy of diagnostic criteria for ARVC when applied to athletes exhibiting electrocardiographic TWI and to identify discriminators between physiology and disease. METHODS: The study population consisted of athletes with TWI (n = 45), athletes without TWI (n = 35), and ARVC patients (n = 35)...

OBJECTIVES: Aberrant origin of the coronary arteries is rare but can be life threatening. It is an important cause of sudden death in athletes and other young adults, and may be treated surgically. Consensus exists that interarterial left coronary artery (LCA) should be surgically repaired. For interarterial right coronary artery (RCA), the discussion remains open. The purpose of this study was to analyse our surgical experience. METHODS: From 2001 until 2014, 31 patients were operated for interarterial RCA, interarterial LCA or intraseptal course of the LCA...

Vasovagal (neurocardiogenic) syncope, a subtype of reflex syncope, has many well-known triggers. However, we found no previous report of vasovagal exercise-induced syncope in a sedentary person. We present the case of a 35-year-old sedentary woman who experienced vasovagal syncope as she underwent an exercise stress test. Results of evaluations, including resting and stress electrocardiography and echocardiography, were normal. Her presentation is highly unusual: syncope has typically not been associated with exercise except in young athletes, people with structural heart abnormalities, or people with a prolonged QT syndrome...

BACKGROUND: Pre-participation cardiovascular evaluation is being recommended by a growing number of sporting bodies and scientific organisations in an attempt to identify athletes harbouring quiescent cardiac conditions which put them at risk of exercise-related sudden cardiac death (SCD). However cardiac adaptation to exercise may itself result in ECG patterns that overlap with those observed in several cardiac conditions, including hypertrophic cardiomyopathy (HCM), the leading cause of SCD in athletes worldwide...

Sudden deaths occurring during exercise are rare and are most commonly due to cardiac arrest. It is most commonly underlain by symptomless cardiomyopathy or coronary artery disease. Preventive work comes up against a diagnostic problem in distinguishing adaptational changes of the athletic heart from a heart disorder. To reveal the danger of cardiac arrest and reduce human tragedies international sports organizations and cardiologic expert groups recommend screening of cardiac disorders among competing athletes...
