RESUMO
Intensive and prolonged practice of sport can lead to cardiovascular and electrocardiographic changes. The purpose of this study was to describe the electrocardiographic changes in some young black Senegalese players practicing competitive basketball. We conducted a prospective descriptive analysis of surface electrocardiogram (ECG) findings related to young Senegalese Black players practicing competitive basketball. The study involved 40 young basketball players, 20 girls and 20 boys, whose average age was 17 ± 0.86 years (ranging from 17 to 19 years) and 15 ± 1.56 years (ranging from 13 to 18 years) respectively. Heart rate was lower among boys, 59 beats ± 9 beats (ranging from 42 to 85) than among girls 73 beats/ min ± 11 beats (ranging from 50 to 95) (p = 0.0004). The following features have been observed: repolarization abnormalities such as T-wave inversion V1-V4 in 3 cases (7.5%), right ventricular hypertrophy in 1 case (2.5%), right axis deviation (QRS axis) in 1 case (2.5%). Intensive and prolonged practice of basketball leads to electrocardiographic changes in the young black Senegalese players.

Poorly tolerated cardiac rhythm disorders in the newborn are a real emergency requiring early and adequate management. We here report the case of 15-day old newborn with atrial tachycardia associated with acute heart failure requiring electrical cardioversion.

Poorly tolerated broad QRS complex tachycardia in a newborn poses problems with its diagnosis and emergency management. We report the case of a 35-day-old newborn with broad QRS complex tachycardia admitted because of cardiocirculatory distress. Doppler echocardiography showed morphologically normal heart. The patient received a loading dose of amiodarone but it didn't attenuate tachycardia. Normal sinus rhythm was restored after cardioversion through Lifeline semi-automatic external defibrillator. Maintenance therapy was based on oral amiodarone. The patient had normal sinus rhythm at 03 months of follow-up.
