Smartphone-based technology for electrocardiographic recording is now part of the new concept of mobile health in both human and veterinary medicine. Although smartphone-based ECG for electrocardiographic screening in dogs is reliable, one-lead ECG devices have mainly been evaluated. This prospective study assessed the feasibility and the diagnostic reliability of a new smartphone-based six-lead electrocardiograph (smECG) in dogs, in comparison to a standard six-lead electrocardiograph (stECG). All ECG tracings were blindly reviewed by an expert operator, who judged whether tracings were acceptable for interpretation, performed the electrocardiographic measurements, and assigned a diagnosis. The agreement in the electrocardiographic interpretation and diagnosis between smECG and stECG was assessed using the Bland-Altman test and Cohen's k test. The study included 108 client-owned dogs. The tracings obtained by the smECG were interpretable in 100 % of cases. No clinically relevant differences between smECG and stECG were found in the assessment of heart rate, interval duration, and QRS mean electrical axis. The smECG tended to underestimate the amplitude of the P and R waves. Perfect agreement was found in the detection of sinus rhythm, atrial fibrillation, ventricular arrhythmias, atrioventricular blocks, and bundle branch blocks. Our study suggests that the tested smartphone-based six-lead ECG is a clinically reliable device for the assessment of heart rate and heart rhythm in dogs, and thus could be used in a clinical setting in dogs and for telemedicine.
基于智能手机的心电图记录技术现在是人类和兽医医学中移动健康新概念的一部分。虽然基于智能手机的心电图用于犬心电图筛查是可靠的，但主要评估的是单导联心电图设备。这项前瞻性研究评估了一种新的基于智能手机的六导联心电图（smECG）在犬中的可行性和诊断可靠性，与标准六导联心电图（stECG）相比。所有心电图记录均由一名专家操作员进行盲法审查，该操作员判断记录是否可用于解释，进行心电图测量，并给出诊断。使用 Bland-Altman 检验和 Cohen's k 检验评估 smECG 和 stECG 之间在心电图解释和诊断方面的一致性。该研究纳入了 108 只患犬。smECG 获得的心电图记录在 100%的情况下可解释。在评估心率、间期持续时间和 QRS 平均电轴方面，smECG 和 stECG 之间未发现临床相关差异。smECG 倾向于低估 P 和 R 波的幅度。在检测窦性节律、心房颤动、室性心律失常、房室传导阻滞和束支传导阻滞方面，发现了完美的一致性。我们的研究表明，经过测试的基于智能手机的六导联心电图是一种用于评估犬心率和心律的临床可靠设备，因此可用于犬的临床环境和远程医疗。
