[{'content': "ECG features of Athlete's Hea include all of the following except: \nSelect and explain. \nA. High QRS Voltage, B. Early repolarization, C. Tall peaked T waves, D. Shoened QT Interval", 'role': 'user'}, {'content': "Answer: D \nExplanation: Answer is D (Shoened QTc Interval) Athletes Hea is associated with a prolonged QT Interval and not a shoened QT interval. Athlete's hea is usually associated with a prolonged QT interval because of bradycardia. When corrected for hea rate the QT Interval (QT c) is usually at the upper limit. Common ECG findings in Athletic Hea syndrome Sinus bradycardia Sinus arrhythmia First-degree AV block Second Degree Hea Block (Mobitz 1; Wenckebach AV block) Incomplete RBBB Notched p waves (increase in amplitude and duration) RVH by voltage criteria (High QRS Voltage) LVH by voltage criteria (High QRS Voltage) Early repolarization changes Prolonged QT Interval (Due to bradycardia) QTc interval at upper limit (QTc is QT Interval corrected for Hea Rate) Tall, Peaked T waves Prominent U Waves", 'role': 'assistant'}]
