Ventricular Fibrillation Home > Conditions & Treatments > Arrhythmia > Ventricular Fibrillation. Ventricular fibrillation is a condition in which the heart's electrical activity becomes disordered. When this happens, the heart's ventricles, the lower chambers that pump blood, contract in a rapid, unsynchronized way. The ventricles flutter rather than beat, causing the heart to pump little or no blood. Ventricular fibrillation is life-threatening and requires prompt treatment. Collapse and sudden cardiac death will follow in minutes unless medical help is provided immediately.

- From Wikipedia, the free encyclopedia. Ventricular fibrillation (V-fib or VF) is a condition in which there is uncoordinated contraction of the cardiac muscle of the ventricles in the heart, making them quiver rather than contract properly.entricular fibrillation is the most commonly identified arrhythmia in cardiac arrest patients. While there is some activity, the lay person is usually unable to detect it by palpating (feeling) the major pulse points of the carotid and femoral arteries. Such an arrhythmia is only confirmed by electrocardiography.

- Quink (a portmanteau word from 'quick' and 'ink') is a fountain pen ink developed by the Parker Pen Company.The ink was novel for using isopropyl alcohol as a solvent, which dried by absorption rather than evaporation of previous water-based inks.However the composition of the ink damaged some pen barrels and caps.lthough Quink was indeed ideal for use with the 51, Parker's other pens of this generation were just as capable of using it. The Parker 51 was only made available in 1941, ten years after Quink's development.

- Atrial fibrillation (A-fib) is a type of cardiac arrhythmia, or irregular heartbeat. In a healthy heart, blood moves into your atria and then into your ventricles. The ventricles are the lower chambers of your heart. From there, blood flows around your body and back to your heart.

Overview Atrial fibrillation. Overview. Atrial fibrillation is an irregular and often rapid heart rate that can increase your risk of stroke, heart failure and other heart-related complications. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart.

- An arrhythmia that starts in your ventricle is called ventricular fibrillation. This occurs when the electrical signals that tell your heart muscle to pump cause your ventricles to quiver instead. The quivering means that your blood is not pumping blood throughout your body.ecause V-fib can lead to cardiac arrest and death, it requires immediate medical attention. A defibrillator is an electronic device used to treat V-fib. It produces an electric shock that can restore a normal heartbeat.

Understanding Atrial Fibrillation If you regularly experience a rapid or irregular heartbeat, you may be experiencing atrial fibrillation. Atrial fibrillation is a condition that occurs when the upper chambers of your heart receive irregular electrical signals. The chamber responds by quivering, which in turn overloads the AV node between the atria and the ventricles. The result is the irregular heartbeat called atrial fibrillation.

Overview By Mayo Clinic Staff. Ventricular fibrillation is a heart rhythm problem that 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.

Shockable Rhythms Ventricular Fibrillation. Ventricular fibrillation, or v-fib, is a common cause of out-of-hospital cardiac arrest. In this case, the heart quivers ineffectively and no blood is pumped out of the heart. On the monitor, v-fib will look like a frenetically disorganized wavy line.ine v-fib is sometimes mistaken for asystole. As the treatments for asystole and ventricular fibrillation are different, it is important to differentiate between the two. If in doubt, it is acceptable to deliver a shock.

What Is Atrial Fibrillation? Atrial fibrillation, often referred to as afib, is an irregular heartbeat, a rapid heartbeat, or a quivering of the upper chambers of the heart, called the atria. Atrial fibrillation is due to a malfunction in the heart's electrical system, and is the most common heart irregularity, or cardiac arrhythmia. For more detail about how the heart works and what happens to the heart when it is in atrial fibrillation, see About the Heart.

Atrial Fibrillation: Diagnosis and Treatment Atrial fibrillation is the most common cardiac arrhythmia. It impairs cardiac function and increases the risk of stroke. The incidence of atrial fibrillation increases with age. Key treatment issues include deciding when to restore normal sinus rhythm, when to control rate only, and how to prevent thromboembolism.

What is Auricular Fibrillation? Auricular fibrillation is the same as atrial fibrillation. It is a heart arrhythmia- where the heart beat does not beat at a normal pace or rate. Atrial arrhythmia is diagnosed as rapid and random contractions of areas inside the atrium of the heart, which cause totally irregular and often very rapid, ventricular heart rate.

How does digoxin treat atrial fibrillation? Atrial fibrillation (AF or A-Fib) is a heart rhythm disturbance, that causes an irregular and often very rapid, fluttering heart rate (heart palpitations). A-Fib occurs when the upper chambers of the heart (the atria) beat chaotically and out of sync with the lower chambers (the ventricles).

A Complete List of AFib Medications Atrial fibrillation (AFib) is a type of arrhythmia, or abnormal heart rhythm. According to the American Heart Association, it affects about 2.7 million Americans. People with AFib have an irregular beating of the heart’s upper chambers, called the atria. The atria beat out of synch with the lower chambers, called the ventricles. When this happens, not all blood gets pumped out of the heart. This can cause the blood to pool within the atria. Clots can form when the blood pools.

Overview Atrial fibrillation (AFib) is a medical disorder that affects the upper chambers, known as atria, of the heart. People with AFib experience irregular heartbeats caused by abnormal electrical signals in the atria. The electrical impulses erroneously circulate through the atria, causing the atria to contract with an irregular rhythm and fast rate.

Ventricular Fibrillation Ventricular Fibrillation. Ventricular fibrillation (VF) is a condition in which your heart beats in an abnormal rhythm. While your heart typically beats in a regular, steady pattern, VF causes your heart to beat quickly and out of rhythm. This is an emergency condition that may be brought on by a heart attack.hen VF occurs, the two ventricles (chambers) in the lower portion of your heart are not able to pump hard enough to move blood through your body. This makes your blood pressure drop quickly and keeps blood from traveling through your body. As a result, blood cannot get to your vital organs.

Ventricular Fibrillation Defined Ventricular Fibrillation is the most common arrhythmia in cardiac arrest patients. The only method by which to confirm this arrhythmia is by electrocardiography. The treatment of such an arrhythmia is included in the ACLS pulseless arrest Algorithm. Ventricular Fibrillation is a shockable rhythms and is treated in a similarly to Ventricular Tachycardia (VT). The pulseless arrest algorithm has been established as the best practice in treating ventricular fibrillation.

atrial fibrillation atrial fibrillation (AF) a cardiac arrhythmia characterized by disorganized electrical activity in the atria accompanied by an irregular ventricular response that is usually rapid. The atria quiver instead of pumping in an organized fashion, resulting in compromised ventricular filling and reduced stroke volume.

Overview The cause of ventricular fibrillation isn't always known. The most common cause is a problem in the electrical impulses traveling through your heart after a first heart attack or problems resulting from a scar in your heart's muscle tissue from a previous heart attack. Some cases of ventricular fibrillation begin as a rapid heartbeat called ventricular tachycardia (VT).

Paroxysmal (Lone) Atrial Fibrillation Frequently Asked Questions Atrial fibrillation is characterized by a rapid, irregular heart beat and can be paroxysmal (intermittent) or permanent in nature. It is caused by a dysfunction of the heart tissue or nodes, by a dysfunction of the autonomic nervous system or by a combination of both.

- Fibrillation – A chaotic and unsynchronised quivering of the myocardium during which no effective pumping occurs. Fibrillation may occur in the atria or the ventricles. Heart Block – A condition in which electrical impulses are not conducted in the normal fashion from the atria to the ventricles. May be caused by damage or disease processes within the cardiac conduction system.
