AFIB vs Tachycardia: Difference and Comparison

The heart is one of the most vital organs of the human body. One must take care of their heart to live a healthy and long life.

Various heart diseases may cause trouble to people who lie in the age group of 30-70 years. Atrial fibrillation, or afib and tachycardia, are two abnormalities of the heart rhythm.

Key Takeaways

  1. Afib, or atrial fibrillation, involves irregular and rapid heartbeats in the atria, while tachycardia denotes a fast heart rate.
  2. Afib increases the risk of blood clots and stroke, while tachycardia can cause complications like heart failure and sudden cardiac arrest.
  3. Doctors use different treatments for Afib and tachycardia, depending on the severity and underlying causes.

AFIB vs Tachycardia

AFib can cause symptoms such as palpitations, shortness of breath, and dizziness and can lead to stroke, blood clots, and heart failure. Tachycardia is a fast heartbeat that exceeds 100 beats per minute, caused by stress, anxiety, exercise, medications, or underlying medical conditions.

AFIB vs Tachycardia

Afib or atrial fibrillation is the rapid or irregular heart rate that can significantly increase the chances of strokes, heart failure, and other types of heart diseases. The major symptoms of Afib include shortness of breath, sweating, fatigue, and heart palpitations.

Tachycardia is a heart condition in which the rate of heartbeat is abnormally high (100 beats per minute). This may happen due to an increased pumping rate in one of the heart chambers or even in both chambers.

The efficiency of decreases with the increase in heart rate.

Contraction of heart musclesThe heart muscles in the case of afib or atrial fibrillation do not contract at regular intervals.The heart muscles in the case of tachycardia contract regularly.
SymptomsThe major symptoms of afib are palpitations, fatigue, dizziness, and shortness of breath.The major symptoms of tachycardia are confusion, chest pain or discomfort, and low blood pressure.
CausesThe main causes of afib may be coronary artery disease, high blood pressure, and lung diseases.The main causes of tachycardia may be excessive smoking and drinking, hypertension, and electrolyte imbalances.
PreventionSome of the ways to prevent afib are eating a healthy diet, avoiding smoking, and maintaining a healthy weight.Some of the ways to prevent tachycardia are eating the right quantity of food, avoiding smoking, and doing regular exercise.

  • Fatigue and weakness are two major symptoms of afib.
  • Chest pain and reduced capability of exercise are also some symptoms of afib.
  • Weakness and dizziness are also two indications of afib.

There are various types of atrial fibrillation, like occasional afib, persistent afib, permanent afib, and long-standing persistent afib. These types differ in intensity, timings, and nature.

If you are experiencing symptoms of Atrial fibrillation, then you should immediately fix an appointment with your doctor and get the necessary checkups done.

The main causes of afib or atrial fibrillation are:-

  • One of the major reasons for afib may be increased blood pressure or any sort of coronary artery disease.
  • Various types of metabolical imbalances and an overactive thyroid gland may also be a reason for atrial fibrillation.
  • If an individual has previously suffered from heart disease and undergone heart surgery may also be prone to afib.

What is Tachycardia?

It is a heart condition where the rate is abnormally high that is around 100 beats per minute. Our blood circulation will come down initially if the heart pumps quickly and at a faster rate. Persistent tachycardia may result in a heart attack.

The main symptoms of tachycardia are:-

  • If an individual suddenly faints on a regular basis, then he may suffer from tachycardia.
  • Hypotension or low blood pressure may also indicate the chance of tachycardia.
  • Constant shortness of breath and palpitations also indicate the chance of tachycardia in an individual.

  1. AFIB is a heart condition that is characterized by rapid and continuous heartbeat, whereas tachycardia is a heart condition characterized by a high abnormal heart rate.
  2. The heart muscles, in the case of afib, do not contract on a regular basis. On the other hand, in tachycardia, the heart muscles contract regularly.
  3. High blood pressure may be the main reason for afib, whereas low blood pressure may be a reason for tachycardia.
  4. The main symptoms of afib are palpitations, fatigue, and dizziness, whereas the symptoms of tachycardia are shortness of breath and low blood pressure.
  5. One of the ways to prevent afib is to avoid smoking and drinking, whereas to prevent tachycardia is to exercise regularly.
