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). QRS morphology in VF varies in shape, amplitude, and duration with a prominent irregular rhythm.
On an EKG, ventricular arrhythmias are characterized by wide QRS complexes (≥0.12 secs), reflecting the abnormal, delayed conduction pathway through the ventricular myocardium rather than the normal conduction system.
Ventricular fibrillation can occur due to coronary heart disease, valvular heart disease, cardiomyopathy, Brugada syndrome, long QT syndrome, electric shock, or intracranial hemorrhage. [2][1][6] Diagnosis is by an electrocardiogram (ECG) showing irregular unformed QRS complexes without any clear P waves. [1]
Ventricular fibrillation (VF) occurs when there are uncoordinated contractions within the ventricles of the heart. The primary cause of VF is hypoxia (lack of oxygen) to the heart muscle, which causes hyperirritability in the cardiac muscle tissue.
10 lis 2022 · This article is a guide for interpreting abnormal Ventricular Fibrillation EKGs, including qualifying criteria and a sample EKG rhythnm strip. Ventricular fibrillation is an abnormal, irregular heart rhythm with uncoordinated electrical activity and contractions.
