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 moreHow is ventricular fibrillation presented on ECG?
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 ventricular fibrillation be detected by ECG?
Electrocardiogram (ECG or EKG). An ECG can show if your heart is beating too fast, too slow or not at all. If you’re having an episode of ventricular fibrillation, the ECG usually shows a heartbeat of about 300 to 400 beats a minute .

Read moreCan stress cause ventricular fibrillation?
Chronic stress can lead to reduced heart rate variability, increased QT dispersion and reduced baroreceptor sensitivity. Patients with greatest changes in the cardiac neural regulation associated with increased sympathetic activity due to stress have the greatest risk for developing fatal ventricular arrhythmias [9].
Read moreWhat is the first treatment for ventricular fibrillation?
The first response to V-fib may be CPR . This will keep your blood moving to important organs. Defibrillation. This is an electrical shock that is delivered to your chest wall to restore normal rhythm.
