Lead II electrocardiography in standing and right lateral recumbency in dogs with normal echocardiographic heart chamber values

The electrocardiographic (ECG) exam has been routinely used in veterinary cardiology with reference values available for the right lateral recumbent position. Many situations require the exam to be performed in the standing position. The study presents that the quality of the ECG recording is comparable for the standing and right lateral recumbent positions, as well as significant differences of the P, S and T waves recorded in two positions.
