| 中文描述 | 心房中的節律點可能會天然地過早在正常節律點釋放訊號前發出不正常的訊號導致心室上方心搏過早，可由仔細地聽診發現。第二心音強度低於正常大小，且可能有代償期。心跳的脈搏通常較正常微弱，但牛卻非如此。這種情況通常被認為是一種心臟疾病的徵兆。由心電圖確認診斷。 |
| 英文描述 | There can be spontaneous discharge of an aberrant pacemaker in the atrium before the normal pacemaker discharges, leading to a supraventricular premature beat, which can be picked up on careful auscultation. The second heart sound will be of less than normal intensity, and there can be a compensatory pause. The pulse is generally weaker than normal on that beat, although that was not true in cattle. This is usually considered a sign of heart disease. Dx confirmed by electrocardiography. |
