What is Atrial Fibrillation

Atrial FibrillationA normal heart beats between 60 and 100 per minute when resting but someone with Atrial Fibrillation this may be increased to over 140 beats per minute and be irregular.  You may detect this when caring for someone by a pulse check. In the heart of someone with the condition, the upper chambers of the heart called Atria contract randomly and so fast that they do not allow complete filling of the chamber and do not relax correctly between contractions therefore reducing the efficiency of the heart.

There are about 500,000 people in the UK with the condition and it is the most common heart rhythm disturbance.  The condition affects the person by fast irregular heartbeat, out of breath, dizziness as well as other symptoms but in some people it has no sign or symptoms.  It can affect adults of any age but it affects more as you get older and more men than women.  About 10% of over 75’s have the condition and risk is increased in people who excessively smoke or drink. It is also more likely to affect people with high blood pressure, heart valve problems and other conditions. Read the rest of this entry →
