An arrhythmia (also called dysrhythmia) refers to what is usually an irregular heartbeat. The heart rate can be fast, slow, or irregular, taking into consideration age and activity. For example, a newborn's heart beats much faster than a 5-year-old child's heart. A fast heart rate is called tachycardia. A slow heart rate is called bradycardia. Some irregular heartbeats are normal: Sinus arrhythmia is the normal variation in heart rate that accompanies breathing in and out.
Image Source. The awesome-looking Toyger is probably the most remarkable striped breed of cat in the world. This breed is the result of breeding domestic shorthaired Tabbies to make it looks like a âtoy tigerâ. The breeding started in the 1980s.
The biggest species of the cat family, the tiger is a solitary hunter. They can reach 3.3 meters and weigh up to 300lbs. They stalk their prey and hunt at night. Like lions, they tend to bite the throat of their prey to cut the flow of air and blood to the animals head. They have a powerful bite, nearly twice that of the lion. There are more tigers in captivity than in the wild.
