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.
The temperament of the typical Afghan Hound can be aloof and dignified, but happy and clownish when it's playing. This breed, as is the case with many sighthounds, has a high prey drive and may not get along with small animals. The Afghan Hound can be a successful competitor in dog agility trials as well as an intuitive therapy dog and companion. Genomic studies have pointed to the Afghan Hound as one of the oldest of dog breeds. The breed has a reputation among some dog trainers of having a relatively slow obedience intelligence as defined by author Stanley Coren in The Intelligence of Dogs.
