Ventricular fibrillation is a type of irregular heart rhythm (arrhythmia). During ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner. As a result, the heart doesn't pump blood to the rest of the body.
Ventricular fibrillation requires emergency medical treatment to prevent sudden cardiac death. The goal of emergency treatment is to restore blood flow as quickly as possible to prevent organ and brain damage.
During atrial fibrillation, the heart's upper chambers — called the atria — beat chaotically and irregularly. They beat out of sync with the lower heart chambers, called the ventricles. For many people, AFib may have no symptoms. But AFib may cause a fast, pounding heartbeat, shortness of breath or light-headedness.
A life-threatening complication of V-tach is ventricular fibrillation, also called V-fib. V-fib can cause all heart activity to suddenly stop, called sudden cardiac arrest. Emergency treatment is needed to prevent death.
Ventricular fibrillation. In a typical heart rhythm, electrical signals travel from the heart's upper chambers (atria) to the heart's lower chambers (ventricles), causing the ventricles to contract and pump blood.
Make your tax-deductible gift and be a part of the cutting-edge research and care that's changing medicine. Without fast treatment, this heart rhythm problem can cause death within minutes. Learn the symptoms of VFib and what actions to take to save a life.
Less commonly, ablation is done using a scalpel during open-heart surgery. There are several types of cardiac ablation. The type used to treat atrial fibrillation depends on your specific symptoms, overall health and whether you're having another heart surgery. Atrioventricular (AV) node ablation.
A type of arrhythmia called ventricular fibrillation can cause a dramatic drop in blood pressure. This can cause the person to fall to the ground within seconds, also called collapse. Soon the person's breathing and pulse will stop.
Uncontrolled high blood pressure is the most common cause of left ventricular hypertrophy. Complications include irregular heart rhythms, called arrhythmias, and heart failure. Treatment of left ventricular hypertrophy depends on the cause. Treatment may include medications or surgery.
A Mayo Clinic healthcare professional delivers specialized care for ventricular tachycardia. Ventricular tachycardia that lasts longer than 30 seconds, called sustained V-tach , needs emergency medical treatment.
