Difference Between AFIB and CHF (With Table)

In the human body, there are various organs to be found. These organs perform a variety of functions. Different organs have a variety of responsibilities in the human body, each with its own set of requirements. When all of a person’s organs are in good working order and are in good health, they can function appropriately. The human people themselves must take care of them during their lives. Every organ in the body must function properly for the body to function correctly, and this can only be accomplished if a person has cultivated a sense of balance in their life.

Whether through nutrition or lifestyle, one must maintain good health to avoid diseases, disorders, and any other type of ailment. Nevertheless, if the human heart does not operate correctly or is not healthy, it can cause various health problems. AFIB, also known as atrial fibrillation, and CHF, often known as congestive heart failure, are two of these conditions.


The main difference between AFIB, also known as atrial fibrillation, and CHF, also known as congestive heart failure, is the underlying cause of each illness. On the other hand, it is believed that difficulties with the heart valves cause atrial fibrillation. Congestive heart failure results when the coronary arteries are weakened due to a heart attack or another disease.

Atrial fibrillation, also known as AFIB, is a heart condition in which the atria or chambers of the human heart do not beat in rhythm or do so in an erratic manner. Many factors contribute to its development, but the most common are high blood pressure and abnormalities with the heart’s valves, both preventable. Medication can be used to treat and cure this condition, and there are a variety of additional therapeutic choices available.

Congestive heart failure, also known as CHF, is a condition in which the heart’s pumping function is impaired, resulting in the accumulation of fluids in the body and fluids in the body. Several different diagnostic procedures can detect CHF. The most common diagnostic methods are an ECG or a chest X-ray.

Comparison Table Between AFIB and CHF

Parameters of ComparisonAFIBCHF
Full formsHaving an erratic heartbeat is known as atrial fibrillation.A common medical illness affecting the heart, congestive heart failure (CHF).
Meaning/ DefinitionAtrial fibrillation, also known as AFIB, is a condition in which the atria present in the human heart either does not beat at all or beat erratically. AFIB occurs when the atria fail to win or beat irregularly.Congestive heart failure, also known as CHF, is a condition in which the heart’s pumping function is impaired, resulting in the accumulation of fluids in the body and fluids in the body.
Risk factorsPeople in the 60-year-old and older age group and those who suffer from high blood pressure or coronary artery disease are more likely to suffer from this ailment.This issue affects patients who have had a family history of heart failure, diabetes, and coronary artery disease, among others.
What happensThe atria have an uneven beat to their rhythm.The fluids build-up due to the heart’s inefficient pumping activity.
SymptomsShortness of breath, difficulties in doing tasks such as exercising, feeling lightness in the brain, etc.It is common to notice swelling in the ankles, weariness, and difficulty breathing.

What is AFIB?

Atrial fibrillation, often known as AFIB, is when the atrial cardiac rhythm is abnormal. People over the age of sixty are more likely to be diagnosed with this severe heart disease than any other. It is a treatable condition that can be cured if the patient takes the right meds and follows the proper procedures.

You may have atrial fibrillation if you have high blood pressure, difficulties with your heart valves, or coronary artery disease. The disease can also be caused by hyperthyroidism, in which excessive thyroxine production from the thyroid gland causes the body’s metabolism to speed up.

The symptoms of atrial fibrillation include difficulty breathing, lightheadedness, exhaustion, and difficulties engaging in activities such as exercise.

It’s still possible to treat atrial fibrillation effectively and even get rid of it entirely in some instances. AV node ablation is one of doctors’ most commonly given or followed therapies. Heat is delivered to the area between the heart’s ventricles and atria via a catheter to kill the not working tissue.

What is CHF?

Congestive heart failure, also known as CHF, is a cardiac condition in which the heart’s ability to pump blood is impaired, causing fluid to build up in the body. If left untreated, it can cause significant harm to the heart and the overall health of the human body.

People with high blood pressure, cardiac valve abnormalities, coronary artery disease, or cardiomyopathy are more likely to have congestive heart failure than those without these factors. Non-diabetics have a lower chance of getting the disease than those with type 2 diabetes. Constipation, fatigue, and shortness of breath are signs of congestive heart failure, depending on which ventricle is afflicted. If your heart’s left ventricle is impacted, you may feel weak and exhausted, have difficulties breathing, or decrease cardiac output.

One may have weariness, ankle swells, and abdominal pain resulting from congested liver if their right ventricle is inflamed. Patients can be healed by making dietary and lifestyle modifications and taking prescribed medication

Main Differences Between AFIB and CHF

  1. Heartbeat irregularities are known as atrial fibrillation (AFIB). However, congestive heart failure (CHF) refers to this.
  2. Atrial fibrillation causes a wide range of symptoms, regardless of which organs are damaged. On the other hand, Congestive heart failure causes various symptoms depending on which ventricle is damaged.
  3. Atrial fibrillation causes an irregularity in the atrial heartbeat. On the other hand, Congestive heart failure causes fluid to accumulate in the body because of the heart’s inability to pump effectively.
  4. If you have a history of congestive heart failure in your family, you are at risk. A family history of atrial fibrillation, on the other hand, precludes a person from developing the condition on their own.
  5. To cure atrial fibrillation, AV node ablation is among the options. On the other side, congestive heart failure therapies include a heart transplant if the severity is more significant, medicine, and lifestyle adjustments.


People can avoid atrial fibrillation (AF) and congestive heart failure (CHF) by eating healthily and exercising regularly. These illnesses can be prevented if a person adopts healthy behaviours and maintains a healthy weight.

People must realize the importance of maintaining healthy body weight and lifestyle. As part of their everyday routine, they should incorporate healthy practices. Mental and physical well-being is essential, and they should strive to maintain a healthy lifestyle.
