Changes in heart rate during exercise and recovery from exercise are mediated by the balance between sympathetic and vagal activity. Since alterations in the neural control of cardiac function contribute to the risk of sudden death, we tested the hypothesis that among apparently healthy persons, sudde...
Competitive sports activity is associated with an increase in the risk of sudden cardiovascular death (SCD) in susceptible adolescents and young adults with clinically silent cardiovascular disorders. Screening including 12-lead electrocardiogram (ECG) has been demonstrated to allow identification of athletes...
Information from the death certificate was not used in the determination of the timing of death. To increase our specificity for "arrhythmic death," we excluded anyone who had evidence of collapse of the circulation (hypotension, exacerbation of congestive heart failure, and/or altered mental ...
Sudden cardiac death (SCD) is one of the most feared manifestations of cardiovascular disease and is responsible for as many as 5% to 15% of total deaths in the United States.1,2 Heart rate–corrected QT interval prolongation has long been established as an important risk factor for SCD, ...
but this value decreased in trained people (around 60 bpm). The exercise training influences the parasympathetic tone, reducing HR [44]. In fact, practicing endurance sport can lead to slow heart rate below 60 bpm at rest, so-called "bradycardia", and it is considered a training status inde...
either by recruiting other veterinary schools in Australia and overseas to supplement this retrospective study, or by collaboration to conduct a prospective study of SUD. A prospective study could implement a standardized approach to necropsy and ancillary testing which may increase the rate of definitiv...
When a heart attack occurs in the left ventricle (left lower pumping chamber of the heart), a scar forms. The scarred tissue may increase the risk of ventricular tachycardia. The electrophysiologist (doctor specializing in electrical disorders of the heart) can determine the exact area causing th...
The downward trend of fatal events from this cardiomyopathy paralleled the concomitant increase in the number of athletes with cardiomyopathies successfully identified and hence disqualified from competition over the screening periods. All these findings suggest that screening athletes for cardiomyopathies ...
