Ventricular Fibrillation

Signs and Symptoms:

Chest pain, rapid heart beat, dizziness, nausea.

Shortness of breath, loss of responsiveness, loss of conciousness.

This is a medical emergency. Call 9-1-1 immediately. Then find an AED and start CPR.

Definition:

Ventricular Fibrillation is the most serious cardiac rhythm disturbance. The lower chambers quiver and the heart can't pump blood, causing cardiac arrest.

- Echocardiogram-Electrophysiology study-Stress test- Holter monitoring-EKG

Assement:-Complete cardiopulmonary assements including heart and lung sounds, cardiac rate and rhythm, on a monitor. -Blood pressure, quality of peripheral pulses, capillary refill, respiratory rate and rhythm. -Watch for dizziness, syncope, hypotension, loss of conciousness and electrolyte imbalance. Diagnosis;-Altered tissue perfusion related to rapid heart rate.Goal: -Patient maintans normal vital signs. - Adequate tissue perfusion.Patient Discharge: - Educate patient on importance of compliance with medications. - Educate patient on importance of reducing controlable factors in their life that contribute to an increased risk of reoccurance.-Educate patient on how pacemaker works and when to call physician.

Treatment:

- Maintain ABCs-Rapid defibrillation is the most important intervention for a patient without a pulse- Low flow oxygen by either nasal cannula or mask helps decrease the rate of PVCs- Maintain CPR-Lidocaine IV may be given to a patient with a pulse-Long term drug use may include propranolol(beta blocker) and lidocaine (antidysrhythmic)-Surgery done to treat underlining cause.

Nursing Role:

Diagnosis:

Causes/Risk factors:

-An exact cause is usually unknown but typically stems from an interuption of the electrical impulses that control your heart beat.- Can be secondary to an MI, heart muscle damage or other heart conditions. - Having previous episodes, use of street drugs, smoking, poor diet, congenital heart disease, and electrocution or other injuries that cause heart muslce damage put you at a greater risk.
