Heart arrhythmia

Heart arrhythmias are disruptions in a regular heart rhythm, which can include slow, irregular or fast heart beats. They occur when the electrical impulses to the heart stray from their normal sequence and can range from being harmless to life-threatening.

Frequently asked questions

What is A-fib? Atrial fibrillation or A-fib is an irregular and often rapid heartbeat in which the top two chambers of the heart, called atria, do not beat in coordination with the two lower chambers of the heart, called ventricles. When the heart is beating in A-fib, it may not pump enough oxygen-rich blood to the rest of the body, which can lead to blood clots as well as causing chest pain, dizziness, weakness and fatigue

What are common symptoms of A-fib? Some people have no symptoms and do not know when their heart is in A-fib. Other people may feel dizziness, shortness of breath particularly with any exertion, chest discomfort, sensations of a racing or pounding heartbeat (palpitations) and weakness or fatigue.

What are the greatest risks of having A-fib? The greatest risks are stroke, heart failure fainting or near-fainting (syncope) and long-term detrimental health effects such as dementia.

What are the signs of a stroke? Healthcare professionals use the acronym FAST:

  • Facial drooping/numbness (ask them to smile)
  • Arm weakness/numbness (ask them to raise both arms)
  • Speech difficulties (ask them to repeat a simple phase like Jack and Jill went up the hill)
  • Time to call 911 if the person fails any part of the test. You should note the time and call 911 for help. Time is the most critical thing!

What are some risk factors for A-fib? High blood pressure, prior heart attack, advanced age, heart disease, heart valve problems, thyroid disease, diabetes, weighing more than you should, sleep apnea, alcohol, family history, stress, not exercising or extreme exercise as well as other less common factors all may cause atrial fibrillation.
