Women and patients who have atrial fibrillation long-term may underestimate afib.When working well, the 4 chambers of the heart contract (squeeze) in an organized way.See a picture of the Heart and learn more about the health topic.

This discharge causes the muscle of the atria and ventricles to contract and pump blood.Signals from the atria must pass through the AV node to reach the ventricles.
Symptoms of Atrial Fibrillation (AFib) - HRSGenetic factors, high salt intake, and increased arterial stiffness cause high blood pressure.The blood then flows from the lungs to the left atrium, and then down into the adjacent left ventricle.Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema.
This reduces the ability of the atria to pump blood into the ventricles.Electrical cardioversion is successful in over 95% of individuals with AF, but 75% of them have a recurrence of the disease within 1 to 2 years.
Live better and be healthier with these quick nutritional tips from the experts.Symptoms of the condition include: Palpitations Dizziness Fainting Weakness Fatigue Shortness of breath Chest pain Some people have no signs or symptoms.During exercise or excitement, the frequency of discharges from the SA node increases, increasing the rate in individuals that are in good clinical health.The current passes from the SA node, through the special tissues of the atria and into the AV node.
Atrial fibrillation (A-fib) is most common cardiac arrhythmia (irregular heart beat), high blood calcium and primary hyperparathyroidism is a leading cause.Primarily a disease of aging, causes of Atrial Fibrillation may be heart, thyroid or lung disease, and is associated with high blood pressure, diabetes, sleep apnea.These drugs may include beta-blockers, calcium channel blockers, and digoxin.What is the normal function of the heart, and how does its electrical system work.This blood flows into the right atrium and then down into the adjacent right ventricle.
A procedure called radiofrequency ablation can be used to scar areas in your heart where the heart rhythm problems are triggered.Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart.

Atrial flutter (AFL) is a common abnormal heart rhythm, similar to atrial fibrillation, the most common abnormal heart rhythm.Atrial fibrillation is a irregular heartbeat (arrhythmia) that can lead to blood clots, stroke and other heart related complications.This is because the sinoatrial node no longer controls the heart rhythm.
The rapid and irregular discharges from the atria then pass through the AV node and into the ventricles, causing the ventricles to contract irregularly and (usually) rapidly.Non-medication treatments of atrial fibrillation include pacemakers, AV node ablation, atrial defibrillators, and the Maze procedure.
