The Underlying Causes of AFib

AFib is a cause for concern to a huge number of individuals all over the world. Also known as Atrial fibrillation, it involves a quivering or an abnormal rate or rhythm in your heartbeat. This basically means that your heart rate is beating too slow or too fast than intended. It should be noted that for adults, their normal resting heart rate can range from 60 to 100 beats a minute. Such is not the cause however, when one is suffering from atrial fibrillation. AFib patients have reported to have 100 to 175 beats per minute which is alarming as it can lead to blood clots, stroke, heart failure and other heart-related complications. Let us consider AFib causes and how it develops.

How AFib Develops

Atrial Fibrillation is often the result of abnormalities or damage to the heart’s structure. AFib cause can stem from high blood pressure, heart attacks, coronary artery disease, abnormal heart valves, heart defects, lung disease, viral infections, stress, sleep apnea and the likes. AFib is often considered as a silent condition especially since it can show no symptoms until it’s discovered during a physical examination making them even more dangerous. Their symptoms include palpitations, weakness, fatigue, lightheadedness, dizziness, confusion, shortness of breath as well as chest pain.

AFib with RVR

Atrial fibrillation with rapid ventricular response is considered to be the most common type of arrhythmia. This often occurs when the lower chambers of the heart, to beat too fast which can result to a rapid or fluttering heartbeat. Atrial fibrillation with rapid ventricular response is something that should not be taken lightly or for granted as it can cause serious complications.

One of the worst case scenario that can happen to a person who has an atrial fibrillation with rapid ventricular response is heart failure resulting to the ventricles not efficiently pump blood out to meet the needs and demands of the body. AFib with RVR can also cause the development of chest pains which makes conditions like congestive heart failure much worse.


For some, AFib does not need any form of treatment. Such is not the case however, with regards to AFib with RVR as it can contribute in making the arrhythmia more serious. During such cases, finding the necessary treatment is heavily advised.

AFib medications can range from beta blockers, calcium channel blockers, and digoxin which are all utilised to slow the ventricular rate in patients with this condition. If medications don’t provide the much needed effect, patients can opt to have an artificial pacemaker installed to them. Regulating the beating of the heart is what this electronic device does which allows patients to achieve safe heart rate levels in a timely and effective manner.

AFib causes a lot of stress to an individual. With that being said, patients should not take all of the load directly on their own. Doctors will be able to help them manage AFib through careful diagnosis and come up with an effective prognosis to reduce its risk.
