The paper describes observations on the distributions of the P, QRS and T cardiac vectors in the horizontal plane, comparing healthy horses with those with arrhythmia and cardiac murmurs. Deviation of the T vector from the normal range appeared to occur most commonly in association with cardiac murmurs, particularly those involving the semilunar valves and aorta.
本文描述了对马匹心脏P、QRS和T向量在水平面分布的观察结果,比较了健康马匹与有心律失常和心脏杂音的马匹。T向量偏离正常范围似乎最常与心脏杂音有关,尤其是那些涉及半月瓣和主动脉的杂音。
