    • A novel method and apparatus for obtaining the electrocardiogram (ECG) in small conscious animals, such as mice, without the need to anesthetize or instrument the animal, are described. The apparatus includes an array of conductive pads, embedded in a platform, the pads sized and spaced to advance contact between an animal's paws and the pads as the animal freely moves upon the platform. Electrical circuitry to the pads is configured to sense the parings of pads and paws that render an interpretable ECG signal and to activate or deactivate recording of the signals. The apparatus is suspended above a surface to minimize the range of motion of the animal without physical restraint. The method and apparatus of the present invention are intended to replace the use of anesthetics or invasive procedures to obtain ECGs in mice, to limit the range of motion of mice without physical restraint or harnessing, and to advance a common level of animal activity for animal-to-animal comparisons of cardiovascular function.

    • The mdx mouse is a model of Duchenne muscular dystrophy. The present invention describes that mdx mice exhibited clinically relevant cardiac phenotypes. A non-invasive method of recording electrocardiograms (ECGs) was used to a study mdx mice (n=15) and control mice (n=15). The mdx mice had significant tachycardia, consistent with observations in patients with muscular dystrophy. Heart-rate was nearly 15% faster in mdx mice than control mice (P
    • mdx小鼠是Duchenne肌营养不良症的模型。 本发明描述了mdx小鼠表现出临床相关的心脏表型。 记录心电图(ECG)的非侵入性方法用于研究mdx小鼠(n = 15)和对照小鼠(n = 15)。 mdx小鼠具有显着的心动过速,与肌营养不良患者的观察结果一致。 mdx小鼠的心率比对照组高出近15%(P <0.01)。 与对照小鼠相比,心电图显示mdx小鼠中速率校正的QT间期持续时间(QTc)显着缩短(P <0.05)。 与对照小鼠相比,mdx基线时PR间期持续时间更短(P <0.05)。 毒蕈碱拮抗剂阿托品在C57小鼠中显着增加心率和减少PR间期持续时间。 矛盾的是,阿托品在所有mdx小鼠中显着降低心率和增加PR间期持续时间。 药理学自主性阻断和压力反射敏感性检测显示,心肌率的自主神经系统调节失调,mdx小鼠副交感神经活动减少,交感神经活动增强。 肌营养不良蛋白缺陷型小鼠的这些心电图发现为诊断,理解和治疗杜氏肌营养不良患者提供了新的基础。

    • An apparatus for non-invasively measuring an electrocardiogram (ECG) in a conscious ambulatory subject includes an electrically conductive platform. The electrically conductive platform establishes an electrical connection with the subject at one of a position forward (e.g., rostral to) or a position rearward (e.g., caudal to) the heart. An additional electrical connection is established at the other of a position forward (e.g., rostral to) or a position rearward (e.g., caudal to) on the subject. The position rearward to (e.g., caudal to) the heart can be the tail of the subject. The additional electrical connection can be established by a movable electrode, an electrically conductive ringlet, an additional electrically conductive platform, a region of conductive material, an electrically conductive dome, a food element, or one or more electrically conductive posts.

    • A method and apparatus for recording and analyzing the gait of an animal is provided. The apparatus can take the form of a gait imaging system. The system includes a movable belt track upon which a subject can ambulate. An imaging device is disposed below the belt track to record contact between at least one limb of the subject and the belt track. The subject can ambulate along the belt track in a substantially stationary location above the imaging device as the belt track moves, and the imaging device can record the contact by the subject. A method of recording a gait of an ambulating subject is also provided. The method includes locating the subject on a movable belt track. The subject is motivated to ambulate along the movable belt track at about the same rate as the movable belt track, while the belt track is moving, such that the location of the subject does not substantially change. Contact made by at least one limb of the subject with the belt track is recorded with a recording device underneath the belt track. Additional kinematic analysis can occur of the subject's gait. The method of recording can further include transmission of the gait images to a computing apparatus. The computing apparatus can identify footprint image data, including filtering out unwanted noise. The computing apparatus can then carry out the kinematic analysis, including calculation of physiological information relating to the subject.
