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.
Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not.Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests.
You might also notice other symptoms such as swollen lymph nodes, conjunctivitis, ulcers in the mouth, discharge from eyes, and even anorexia, according to Davis.
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 ...
