Fibrillation is a heart condition where the heart beats irregularly and rapidly. Atrial fibrillation affects the heart’s upper chambers and can be treated with medication, surgery, or electrical cardioversion. Ventricular fibrillation is a serious medical emergency that can lead to death if not treated immediately. It affects the heart’s lower chambers and can occur in both diseased and healthy hearts.
Fibrillation, also known as cardiac arrhythmia, is a natural phenomenon of the heart that can be a serious condition. During fibrillation, the heart beats irregularly and rapidly, with unsynchronized contractions. A fibrillation falls into one of two categories: an atrial fibrillation or a ventricular fibrillation.
Patients with atrial fibrillation experience the condition throughout their lives, although it can be treated with blood thinner medications. Other treatments may include surgery and electrical cardioversion. The condition specifically affects the atria, which are the heart’s two upper chambers. With atrial fibrillation, the electrical impulses that normally send signals to the heart are disorganized. This leads to the irregular heartbeats that the person experiences.
Atrial fibrillation occurs more often in the elderly, although it can occur at any age. Also, it is possible for a person to alternate between having a normal heart rhythm and experiencing atrial fibrillation. There are usually no symptoms associated with atrial fibrillation, although a person may experience chest pains, fainting, palpitations and, in more extreme cases, heart failure. A person suffering from atrial fibrillation is also more likely to have blood clots, which can travel to the brain and heart.
Cardiac arrest is caused by ventricular fibrillation. Regardless of what it leads to or what it is caused by, ventricular fibrillation is a serious disease that can quickly lead to death if the situation is not reversed through a process called defibrillation. For this reason, ventricular fibrillation is considered a medical emergency.
A person with ventricular fibrillation has heart muscles that are unable to coordinate with the large chambers, or ventricles, in the heart. This causes the ventricular muscle to contract and contract in an unusual way. As a result, the ventricles do not pump blood through the arteries. If left untreated, the heart will stop working completely. In fact, it only takes a few seconds for the patient’s blood to stop circulating, which will cause the pulse, breathing and blood pressure to stop.
For the most part, ventricular fibrillation occurs in diseased hearts. At the same time, it can occur in hearts that appear healthy and strong. For these reasons, researchers are still unsure of the exact cause of the disorder.
