Sentences with phrase «ventricular fibrillation»
Ventricular fibrillation is a condition where the heart's lower chambers start shaking in an abnormal way, preventing them from pumping blood effectively. This can be very dangerous as it can lead to a sudden stoppage of the heart, which is a medical emergency. Full definition

Patients who experienced SCA related to sexual activity also had a higher rate of ventricular fibrillation / tachycardia than those who did not.
This trial is the first and largest randomized, double - blind, placebo - controlled study to assess the impact of amiodarone and lidocaine on survival to hospital discharge after out - of - hospital cardiac arrest triggered by two types of dangerous heart rhythms known as ventricular fibrillation and pulseless ventricular tachycardia.
In a test of this theory, researchers have demonstrated that mice harboring a human SCN1A gene mutation that results in Dravet Syndrome (DS), a severe and intractable genetic epilepsy, have electrical disturbances in the heart that culminate in ventricular fibrillation and sudden cardiac death.
Alternatively, it could cause ventricular fibrillation which essentially refers to disorganized and useless fluttering of the ventricles found in the heart.
Sudden cardiac arrest (SCA) is an electrical malfunction of the heart which causes the heart to beat in an abnormal, chaotic rhythm called ventricular fibrillation (VF).
Defibrillation is a technique used in emergency medicine to terminate ventricular fibrillation or pulseless ventricular tachycardia.
Francis Kim, M.D., of Harborview Medical Center, Seattle, and colleagues evaluated whether early prehospital cooling (lowering body temperature) improved survival to hospital discharge and neurological outcome in cardiac arrest patients with or without ventricular fibrillation (VF).
Previous research has shown carbon monoxide, which is produced naturally in heart cells, can guard against ventricular fibrillation, however the mechanism behind why this happens was unknown.
If the thin wires running to the chambers of the heart detect ventricular fibrillation — an often lethal arrhythmia — the ICD will unleash a burst of electricity to force the heart back into rhythm.

This arrhythmias may degenerate into ventricular fibrillation which is a fatal abnormal rhythm.
According to the American Heart Association, out of the 250,000 sudden cardiac deaths per year, most are believed to be caused by ventricular fibrillation.
Restoring blood flow to the heart following a heart attack can leave patients with ventricular fibrillation, a dangerous heart rhythm which puts people at greater risk of sudden cardiac death.
Women in danger of ventricular fibrillation are about 40 % as likely as white men to get the devices, even though the device is equally effective for both sexes.
Cardiac arrest is the loss of mechanical activity of the heart that often begins as ventricular fibrillation.
Defibrillation is a medical technique used to counter the onset of ventricular fibrillation, (VF) a common cause of cardiac arrest, and pulseless ventricular tachycardia, which sometimes precedes ventricular fibrillation but can be just as dangerous on its own.
Nearly all patients had ventricular fibrillation, the kind of cardiac arrest that can be restored with a shock to the heart.
The most common cause is ventricular fibrillation, the irregular elec...

Ventricular fibrillation, whether brought on by myocardial infarction or as the result of chronic instability of the heart's rhythm, is a killer.
Study participation was restricted to patients with either ventricular fibrillation or ventricular tachycardia who did not achieve a stable heart rhythm after at least one defibrillator shock and, therefore, represent the typical group of those who receive such medications for cardiac arrest in clinical practice.
Cardiac arrhythmias are cardiomyopathies that regroup different pathophysiological syndromes such as atrial fibrillation, tachycardia and ventricular fibrillation.
