A case report of long-term wireless electrocardiographic monitoring in a dog with dilated cardiomyopathy

Wireless electrocardiographic (ECG) sensor attached to the skin and connected to a smart device via low power Bluetooth technology has been used to record more than 500 hours of ECG data in a German shepherd dog with dilated cardiomyopathy (DCM). Wireless ECG monitoring has been used for a period of 6 months. With the wireless body electrodes, the ECG data were obtained while the dog was resting, walking, playing and eating. Atrial fibrillation, ventricular premature complexes, occasional ventricular tachycardia and multiform ventricular beats were observed. Numerous standard 6-lead ECG recordings have been compared to the recordings obtained with wireless body electrodes. Instantaneous and average heart rates and standard duration measurements evaluated with the two devices were identical in all cases. The extended ECG monitoring time with the wireless device increased the diagnostic yield of arrhythmias.
