One of the measures of the strength of an encryption system is how long it would theoretically take an attacker to mount a successful brute-force attack against it. Brute-force attacks are an application of brute-force search, the general problem-solving technique of enumerating all candidates and checking each one.
Ventricular fibrillation is one type of arrhythmia that can be deadly. It occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly instead of pumping blood. Without an effective heartbeat, blood pressure plummets, cutting off blood supply to your vital organs.
You can describe the heart as having two separate systems; the electrical system and the plumbing system. Some electrical irregularities may cause flutter, fibrillation, pauses, brady cardia (slow rate), tachycardia (fast rate) to name some.You could also have an abnormal or imperfect heart (valve, artery, chamber etc.), a blockage due to plaque or hardening of the arteries, a congenital heart defect or something else.ome electrical irregularities may cause flutter, fibrillation, pauses, brady cardia (slow rate), tachycardia (fast rate) to name some.
