An electrocardiogram â abbreviated as EKG or ECG â is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or âwaveâ) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. The right and left atria or upper chambers make the first wave called a âP wave â following a flat line when the electrical impulse goes to the bottom chambers.
With the thick hair, they may appear sluggish at first glance but the Afghan Houndsâ speed, agility, and endurance is legendary. They are fierce hunters with strong jaws and they have relentless attitudes in hunting. As sight hounds, they are alert and always ready to act.
Underneath the magnificent coat of the Afghan hound there is a sinewy, muscled dog that is powerful and quick. Their body structure is built for a long dayâs hunt with enormous paws that can maneuver across the rough terrain. Today, the Afghan hound is a very impressive sight in the dog show ring. This breed, however, is not the dog for the faint of heart; they are very strong-headed dogs, cute and playful as a puppy but solitary and aloof in adulthood.
