Atrial Fibrillation Overview
Atrial fibrillation describes an irregular and often rapid heart rhythm. The irregular rhythm, or arrhythmia, results from abnormal electrical impulses in the heart. The irregularity can be continuous, or it can come and go.
Normal heart contractions begin as an electrical impulse in the right atrium. This impulse comes from an area of the atrium called the sinoatrial (SA) or sinus node, the "natural pacemaker."
- As the impulse travels through the atrium, it
produces a wave of muscle contractions. This causes the atria to contract.
- The impulse reaches the atrioventricular (AV) node in
the muscle wall between the 2 ventricles. There, it pauses, giving blood from
the atria time to enter the ventricles.
- The impulse then continues into the ventricles, causing ventricular contraction that pushes the blood out of the heart, completing a single heartb...

Medical Dictionary
My daughter is 19 years old. About six months ago, she developed severe chest pain with palpitations. She was admitted to the hospital. Her heart rate remained between 130 and 160 for four days. She had a normal echo, normal EKGs and normal lab results. She was sent home on Toprol and has continued to have a rapid heart rate in the 90s to low 100s with activity. She also continues to have chest pain. She has been told it is stress, but she says she does not feel stressed. We had a stress test done and are waiting on the results, but she says the doctor who performed the test told her she was not active enough. She is a non-smoker, non drinker, no caffenine, young woman. She had no health issues before this. Published: September 11 ::
