Abstract
Competitive
athletes are widely regarded as a special group of healthy individuals
with a unique lifestyle who are seemingly invulnerable and often
capable of extraordinary physical achievement. Athlete’s
heart is generally regarded as a benign increase in cardiac mass, with
specific circulatory and cardiac morphological alterations, that
represents a physiological adaptation to systematic training. However,
the clinical profile of athlete’s heart has expanded
considerably over the last several years as a result of greater
accessibility to large populations of trained athletes studied
systematically with, ECG, ambulatory Holter ECG monitoring, stress
test, echocardiography and cardiac magnetic resonance. As a
consequence, there is increasing recognition of the impact that
prolonged conditioning has on cardiac remodeling, which may eventually
mimic certain pathological conditions, such as Brugada
syndrome, with the potential for sudden death or disease
progression. These findings indicate that atrioventricular
conduction system abnormalities may play a fatal arrhythmogenic role
and raise questions regarding the prevention of electrical instability
in young people engaged in active sports. At last many drugs have been
associated with adverse events in Brugada syndrome patients
and have been indicated to provoke the characteristic Brugada
syndrome-linked ECG abnormalities and/or (fatal) ventricular
tachyarrhythmias.
