The aim of this study was to describe the reference intervals of electrocardiographic patterns and values in conscious healthy domestic geese (). Standard bipolar and augmented unipolar limb lead electrocardiograms with a direct writing electrocardiograph were recorded in 14 domestic geese. The durations of PR interval, QRS complex, ST and QT intervals, the net of the QRS complex, and the P and T amplitudes were determined at 50 mm/s and at 1 cm = 1 mV. The polarity waveform was examined. The mean electrical axis in the frontal plane was determined in leads II and III. Data are expressed as means and standard deviations. The mean (SD) heart rate was 153.8 (22.4) beats/min. The QRS complex was mainly negative in leads II and III; it was positive in the augmented vector right, augmented vector left, and augmented vector foot leads. The T wave was positive in leads II, III, and the augmented vector foot lead and was negative in the augmented vector right and left leads. The mean electrical axis ranged between -30° to -140°. Electrocardiogram recordings were well tolerated by the geese. The reference intervals provided here can be used to assist in the interpretation of electrocardiographic patterns in geese.
本研究旨在描述意识健康家养鹅的心电图模式和数值的参考区间。使用直接书写心电图仪记录了 14 只家养鹅的标准双极和增广单极肢体导联心电图。在 50mm/s 和 1cm=1mV 时，测量 PR 间期、QRS 复合体、ST 和 QT 间期、QRS 复合体的净间距以及 P 和 T 波幅度。检查极性波形。在导联 II 和 III 中确定额面电轴的平均方向。数据表示为平均值和标准差。平均（SD）心率为 153.8（22.4）次/分钟。QRS 复合体在导联 II 和 III 中主要为负性；在增广向量右、增广向量左和增广向量足导联中为正性。T 波在导联 II、III 和增广向量足导联中为正性，在增广向量右和左导联中为负性。平均电轴范围在-30°至-140°之间。心电图记录被鹅很好地耐受。此处提供的参考区间可用于协助解释鹅的心电图模式。
