The risk of recurrent VT/VF after a first event, without suppressive therapy is approximately 22% after 1 year and approximately 53% after 2 years. 29-31 Catheter ablation after the first episode of monomorphic VT reduces recurrences of VT (hazard ratios 0.54-0.61 vs controls for recurrent VT at 1-2 years), 31-33 but these studies did not routinely use active controls with AAD therapy (AAD use ...

Aug 30, 2010 · Background—Current resuscitation guidelines (2005 guidelines [G2005]) accelerate ventricular fibrillation (VF) recurrence. We investigated whether patients resuscitated under G2005 spend more time in VF and have better survival rates than patients treated under the 2000 guidelines (G2000). Methods and Results—We analyzed continuous ECG recordings of out-of-hospital cardiac arrests ...

Of these 814,000 patients, approximately 163,000 have an initial recorded rhythm indicating ventricular fibrillation (VF), which hereafter includes pulseless ventricular tachycardia (VT) and rhythms interpreted as shockable by an automated external defibrillator (AED). The incidence of VF has decreased over time in multiple communities .

Jun 1, 2020 · 1. Scope of the Position Statement. This Canadian Cardiovascular Society position statement is focused on the acute and long-term management of sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) in patients with structural heart disease (SHD), defined by the presence of abnormal myocardium and scar.

Oct 18, 2011 · The extent to which VT termination extends survival, however, depends on the severity of the underlying heart disease and associated comorbidities. 3 – 6 The occurrence of VT or VF is associated with increased mortality and heart failure hospitalizations in ICD patients, despite effective termination of the arrhythmia. 7 VT or VF is associated with heart disease severity and, in some ...

VT in structurally normal hearts. VT and VF can be challenging to manage, particularly if they recur despite initial therapy. The diversity of pharmaco-therapy, devices, catheter ablation techniques, and other interventions increases the complexity of management. Prognostic Significance Sustained VT and VF have a high acute mortality

Nov 2, 2010 · For every minute that passes between collapse and defibrillation, survival rates from witnessed VF SCA decrease 7% to 10% if no CPR is provided. 1 When bystander CPR is provided, the decrease in survival rates is more gradual and averages 3% to 4% per minute from collapse to defibrillation. 1,2,5,7 CPR can double 1,3 or triple 4 survival from witnessed SCA at most intervals to defibrillation.
