28 paź 2022 · Ventricular fibrillation is a type of irregular heart rhythm (arrhythmia). During ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner. As a result, the heart doesn't pump blood to the rest of the body.
24 wrz 2024 · Ventricular fibrillation, or VF, is considered the most serious abnormal heart rhythm. VF is extremely dangerous and can lead to sudden cardiac death. Without treatment, the condition is fatal within minutes.
8 sie 2023 · VF is a WCT caused by irregular electrical activity and characterized by a ventricular rate of usually greater than 300 with discrete QRS complexes on the electrocardiogram (ECG). This activity reviews the causes, pathophysiology, and presentation of VF and highlights the role of the interprofessional team in its management. Objectives:
A more complete definition is that ventricular fibrillation is a "turbulent, disorganized electrical activity of the heart in such a way that the recorded electrocardiographic deflections continuously change in shape, magnitude and direction".
Ventricular fibrillation (or v-fib, for short) is an abnormal heart rhythm that makes your lower heart chambers move quickly and randomly. This life-threatening condition affects your lower heart chambers’ ability to pump blood. You need immediate medical care for this condition.
Ventricular fibrillation is a type of arrhythmia, or irregular heartbeat, that affects your heart’s ventricles. Ventricular fibrillation is life-threatening and needs immediate medical attention. CPR and defibrillation can restore your heart to its normal rhythm and may be lifesaving.
The heart is heterogeneous, and the PSs may be more stable in one region than those in another region, or the fibrillation is a mixture of foci and reentry. Whether a single rate constant for birth and one for death to describe the PS dynamics in the entire ventricles or atria are proper or not need to be investigated.
