Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Fibrillation also occurs with individual skeletal muscle fibers. [7] This happens when muscle fibers lose contact with their innervating axon producing a spontaneous action potential, "fibrillation potential" that results in the muscle fiber's contraction.
They may cause symptoms, sickness or the death of the animal. Some diseases are symptomatic in one cat but asymptomatic in others. Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses. Some of these can be treated and the animal can have a complete recovery.
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Cats' eyes are largely similar to ours but with some fascinating differences, and one thing they have that we don't is a third, inner eyelid, called the nictitating membrane.
“Cat colds are usually diagnosed as an Upper Respiratory Infection (URI) and are usually caused by one or more viral and bacterial agents,” says Sakura Davis, a veterinary consultant at CatPet ...
Initial signs of the condition include behavioral changes such as aggression, timidity, hiding, hyperesthesia, loss of motor functions, and polydipsia. [3] Other commonly observed motor signs include gait abnormalities and ataxia, which typically affect the hind legs first.
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
