First of all, what is atrial fibrillation anyway? It is a condition that's characterized by irregular and often rapid heart rate. It happens when the two upper heart chambers (the atria) suffer from chaotic electrical signals. It's usually caused by damage to the sinus node – your heart's natural pacemaker. It produces impulses that start at each heartbeat and controls the pace of the pumping blood. When the sinus node gets damages, atrial fibrillation occurs. The damage may be the result of a few known conditions. These are high blood pressure, heart attacks, congenital heart defects, abnormal valves, and sleep apnea. It can be dangerous and affect some aspects of your daily lives. If not treated right away or timely, it can cause major difficulties. There are few forms of atrial fibrillation – occasional, persistent, long-standing or permanent.
Because of those irregular electric signals, your heart will go into a frenzy. That frenzy can manifest itself through flip-flopping in your chest. It can be visible at certain times. Also, your chest muscles will experience shaking and constant strikes. Note that all this happens from your heart muscles. To see which kind of atrial fibrillation you have, it's best to wait out and see how long it persists. When concluding the duration, you should visit your cardiologist. You should describe to him in detail what have you felt and how long it lasted.
