Tear in My Heart: ECG Interpretation and Common Cardiac Abnormalities

“I know it’s abnormal, but I don’t know what it is” is a great starting point when teaching ECG evaluation to new technicians or veterinary students. Once we know and are familiar with the normal, we can begin to evaluate and recognize the abnormal. Starting with basic normal cardiac anatomy and physiology, we will evaluate normal sinus rhythm and what the P, QRS, and T correspond to anatomically, then delve into common abnormal electrical, flow, acquired and congenital cardiac abnormalities.
