Do the ventricles have same rate as atria in atrial fibrillation?

No, the ventricles do not have the same rate as the atria in atrial fibrillation.

Atrial fibrillation is a heart condition that causes the heart's upper chambers, called the atria, to beat chaotically. This chaotic beating can cause the heart to beat too fast, too slow, or irregularly.

When the atria are beating chaotically, the electrical signals that normally cause the ventricles to contract are not sent properly. This can cause the ventricles to contract too fast, too slow, or irregularly.

In atrial fibrillation, the ventricles usually contract at a slower rate than the atria. This is because the chaotic electrical signals from the atria do not allow the ventricles to fill completely with blood before they contract. As a result, the ventricles do not pump as much blood as they normally do.

This decreased pumping of blood from the ventricles can cause several symptoms, such as fatigue, shortness of breath, and dizziness. In some cases, atrial fibrillation can also lead to stroke, heart failure, and other complications.
