WebThe T wave is quite variable in the dog and cat. In most leads, the T wave may be positive, negative or biphasic. The height of the T wave should not exceed one-fourth the height of the R wave, one-fourth the height of the Q wave (if Q wave is greater than R wave), or 0.5 mV to 1.0 mV in any lead. The T wave should be positive in CV 5 RL in ... WebST and T waves changes may not be apparent in hypertrophic cardiomyopathy, but if there is presence of ST and T waves changes indicates severe hypertrophy or ventricular systolic dysfunction.
