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.
Read moreCan ventricular fibrillation correct itself?
Ventricular fibrillation seldom terminates spontaneously , since several re-entrant wavefronts, independent from each other, coexist, and the simultaneous extinction of all the circuits is unlikely.
Read moreCan ECG detect ventricular tachycardia?
A wearable cardiac event monitor may be used to diagnose tachycardia. This type of portable ECG device records heart activity only during episodes of irregular heart rhythms (arrythmias). An electrocardiogram is the most common tool used to diagnose tachycardia .
Read moreDoes VT always require immediate cardioversion?
Individuals suffering from pulseless VT or unstable VT are hemodynamically compromised and require immediate electric cardioversion to shock them out of the VT rhythm.
Read moreCan stress cause ventricular tachycardia?
Emotional stressors can lead to ventricular ectopic beats and ventricular tachycardia . Though disturbances of cardiac rhythm due to emotional stress are often transient, sometimes the consequences can be seriously damaging and even fatal [11].
Read moreWho is most at risk for ventricular tachycardia?
The condition most commonly affects people who have heart disorders, such as coronary artery disease and cardiomyopathy . A heart rhythm is considered ventricular tachycardia if it has more than 100 beats per minute with at least three ventricular heartbeats in a row.
Read moreCan ventricular tachycardia be cured?
Ablation of ventricular tachycardia has a long history of safety and success. For some patients, ablation completely cures the abnormal rhythm, and no other treatment is needed . Ablation can also improve treatment with an implantable cardioverter defibrillator.10 May 2019
