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 line treatment for ventricular fibrillation?
If the patient remains in ventricular fibrillation, pharmacological treatment should begin. Epinephrine is the first drug given and may be repeated every 3 to 5 minutes . If epinephrine is not effective, the next medication in the algorithm is amiodarone 300 mg.
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.
Read moreWhat medication is given during ventricular fibrillation?
In acute ventricular fibrillation (VF), drugs (eg, vasopressin, epinephrine, amiodarone ) are used after three defibrillation attempts are performed to restore normal rhythm.
Read moreWhat to do if there is ventricular fibrillation?
Emergency treatment for ventricular fibrillation includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called an automated external defibrillator (AED) . Medications, implanted devices or surgery may be recommended to prevent episodes of ventricular fibrillation.
Read moreIs fine VF shockable?
If there is doubt about whether the rhythm is asystole or very fine VF, revert to the non-shockable arm of the algorithm, since: True fine VF is unlikely to be shocked successfully . Repeated shock of fine VF or asystole will cause myocardial injury, from both the electricity delivered and the interruptions to CPR.
Read moreWhat is the most common cause of ventricular fibrillation?
V-fib most commonly occurs during an acute heart attack or shortly thereafter. When heart muscle does not get enough blood flow, it can become electrically unstable and cause dangerous heart rhythms. A heart that has been damaged by a heart attack or other heart muscle damage is vulnerable to V-fib.
