A cardiac condition seen in people who engage in strenuous physical exercise for long periods of time, such as athletes. The heart becomes enlarged on both sides and appears spherical on a chest X-ray. The pulse rate often slows and the pulse pressure also becomes large. This is not necessarily pathological cardiac hypertrophy, and work efficiency actually increases. Source : Heibonsha Encyclopedia About MyPedia Information |
スポーツマンのように長期にわたり,激しい肉体運動を続ける人たちにみられる心臓の状態。心臓は左右に肥大し,胸部X線写真上,球形を呈する。脈拍はゆるやかになり,脈圧も大となることが多い。必ずしも病的な心肥大とはいえず,作業能率はかえって増加している。
