What is measured or can be detected on the ECG of my pet?
The underlying rate and rhythm of the heart can be measured, and this is the most important role of the ECG. Other less important and less diagnostic functions include the orientation of the heart (how it is placed) in the chest cavity, evidence of increased thickness (hypertrophy) of the heart muscle, evidence of damage to the various parts of the heart muscle, evidence of acutely impaired blood flow to the heart muscle (very rare in most animals), and patterns of abnormal electric activity that may predispose the patient to abnormal cardiac rhythm disturbances.
