To clarify my other post: Resting EKGs on humans can and often do, show no abnormalities...it is when the patient is "stressed" (ie connected to 12 lead ekg and then either chemically stressed or put on a treadmill and exercised until heart rates reach specific rates and/ or arrhythemias begin to occur)..., that T waves drop or flip, rhythm and rate disturbances become evident. If you have a heart issue that is just beginning, more often than not, a resting EKG will not be able to see any abnormalities, because your heart is not challenged. I was referring to EKGs more on humans, than your pup....For humans and pets, a holter monitor that is worn over several days continously, will catch abnormalities, whereas one shot taken over the span of 3 minutes on a simple EKG, will probably not reveal anything UNLESS damage has already been done, or if your baby happens to pass out right at the time the resting EKG is being one. |
