Atrial fibrillation with rapid ventricular response is a fancy name for an irregular heartbeat. When your heart's electrical signals aren't working right, it can lead to a heartbeat that's too fast.

Afib can send many electrical signals to the bottom heart chambers (known as the ventricles) and can trigger RVR (rapid ventricular response), which can cause rapid heart rates. If a heart beats ...

From there, the signals travel to the lower chambers of your heart. The basic cause of AFib is disorganized signals that cause the atria of your heart to squeeze very fast and out of sync.

In AFib with rapid ventricular response, the atria (upper chambers ... between the atria and ventricles of the heart and can cause a fast heart rate. Cardioversion may be part of managing AFib ...

From its triggers to its symptoms, atrial fibrillation, or afib, can be unpredictable. Afib is a type of heart rhythm disorder that starts in the upper chambers of your heart, known as the atria.

If it blocks circulation, that clot can cause a stroke—the disruption of blood flow to brain tissue. An estimated 1 in 7 strokes are caused by AFib, according to the Centers for Disease Control ...

Blood clots are one of the more common complications. AFib interferes with the flow of blood through your heart. This can cause blood to pool in your heart’s upper chambers, which can cause ...

It may be hard to separate cause from effect as people with AFib are more likely to develop gastrointestinal issues, but your story of severe cramps just before the onset of AFib is suggestive ...

[1],[2],[3] Patients with AFib-RVR continue to face a significant unmet need for symptom relief. They can experience the burden of symptomatic acute attacks and our market research indicates 30-40 ...

It may be hard to separate cause from effect as people with AFib are more likely to develop gastrointestinal issues, but your story of severe cramps just before the onset of AFib is suggestive that in ...
