Incidence and prognosis of early primary ventricular fibrillation
in acute myocardial infarction.
Ventricular tachycardia (VT) and ventricular fibrillation
(VF) are dangerous abnormal heart rhythms, and the most common causes of sudden cardiac arrest, so they always require the urgent attention of a cardiologist.
Wearable defibrillators delivered 223 inappropriate shocks to 213 people who weren't experiencing ventricular fibrillation
or ventricular tachycardia.
Patients in the ICD-alone group had a recurrence of ventricular tachycardia or ventricular fibrillation
after a median of 6 months, compared with 19 months in patients who underwent ablation before ICD implantation, a significant difference.
To estimate the effect of a increasing chest compression fraction (CCF)--the proportion of time spent performing chest compressions--during cardiac arrest on survival to hospital discharge, researchers analysed data from CPR tracings in patients who had a ventricular fibrillation
or pulseless ventricular tachycardia cardiac arrest prior to the arrival of the emergency medical services.
With that cut-off and other criteria, such as previous ventricular fibrillation
or advanced heart failure, about 1.
Atrial fibrillation is a very rapid beat in the top chamber and does not produce ventricular fibrillation
except in extremely rare circumstances.
NHW readers know ventricular fibrillation
(VF) strikes suddenly and without warning.
It knows if the heart's electrical system is in an abnormal rhythm called ventricular fibrillation
(v fib) or pulseless ventricular tachycardia (v tach).
The VENTAK[R] PRIZM 2[R] AICD automatic implantable cardioverter defibrillators are designed to detect and terminate ventricular tachycardia (VT) and ventricular fibrillation
(VF), as well as provide bradycardia therapy (atrial and/or ventricular pacing).
The prolongation of the QT interval can trigger life-threatening ventricular arrlrythmias, including Torsades de Pointes and ventricular fibrillation
This is very good news to the residents of Thousand Oaks considering that, according to the American Heart Association, early defibrillation is the only treatment to correct ventricular fibrillation
, the most common cause of death from sudden cardiac arrest.
