There is debate over the use of the electrocardiogram (ECG) to screen athletes for disorders associated with sudden cardiac death, but if screening is completed, accurate ECG interpretation is important. Recently, there has been recognition of a normal black athlete repolarization pattern which includes J-point elevation, convex ST-segment elevation, and T-wave inversions in leads V1 to V4 occurring in 5-15% of black athletes. This pattern must be differentiated from T-wave inversions that are associated with hypertrophic cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy. The combination of J-point elevation >1 mm and T-wave inversions confined to leads V1-V4 excludes cardiomyopathy. If T-wave inversions are present in the inferior or lateral leads or there is no J-point elevation, further evaluation for a cardiomyopathy is required. By recognizing this ECG pattern as a normal variant, unnecessary ancillary testing and restriction from sports can be avoided.

D003937 Diagnosis, Differential Determination of which one of two or more diseases or conditions a patient is suffering from by systematically comparing and contrasting results of diagnostic measures. Diagnoses, Differential,Differential Diagnoses,Differential Diagnosis
D004562 Electrocardiography Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY. 12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001145 Arrhythmias, Cardiac Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction. Arrhythmia,Arrythmia,Cardiac Arrhythmia,Cardiac Arrhythmias,Cardiac Dysrhythmia,Arrhythmia, Cardiac,Dysrhythmia, Cardiac
D016757 Death, Sudden, Cardiac Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.
