Tachycardia/Atrial Fibrillation

Overview of Tachycardia/Atrial Fibrillation

Atrial Fibrillation or AFib is the irregular rhythm of the heart. It can be a temporary or permanent condition. AFib usually occurs in older people and rarely in children.

Signs and Symptoms of Tachycardia/Atrial Fibrillation

Atrial Fibrillation or AFib is the type of irregular or quivering heartbeat also known as an arrhythmia that leads to blood clots, stroke, heart failure and other complications.
During AFib, the atria beat irregularly and out of coordination with the ventricles. This can cause palpitations, shortness of breath and extreme weakness.
Atrial fibrillation may not need immediate treatment and may come and go. It is a serious condition but not necessarily life-threatening. Blood clots formed due to AFib can block the blood flow.

Types of Tachycardia/Atrial Fibrillation

AFib symptoms include:

  • Fatigue
  • Weakness
  • Dizziness
  • Shortness of breath
  • Palpitations
  • Chest pain
  • Rapid or irregular heartbeat
  • Sweating
  • Lightheadedness

Causes of Tachycardia/Atrial Fibrillation

Type of atrial fibrillation on the basis of duration of AFib and underlying cause of the condition is as follows:

  • Paroxysmal Fibrillation

This type of AFib happens a few times a year, the heart returns to its normal rhythm on its own or with intervention. This type can turn into permanent AFib as well.

  • Persistent AFib

If arrhythmia lasts more than a week (7 days), it is defined as persistent AFib. This type requires treatment; without it the rhythm does not return to normal on its own.

  • Long-standing AFib

If arrhythmia lasts more than a year or 12 months it is considered long-standing AFib.

  • Permanent AFib

Permanent arrhythmia lasts indefinitely and no further treatment is given to maintain the normal sinus rhythm.

  • Nonvalvular AFib

This type of atrial fibrillation is not caused by a heart valve or its issues.


Risk Factors of Tachycardia/Atrial Fibrillation

AFib is caused by the irregular rhythm of the two upper chambers of the heart. The heart beats at a range of 100 to 175 beats per minute while the normal range is 60 to 100 beats per minute.

Risk factors include:

  • Advanced age
  • Hypertension
  • Underlying heart condition
  • Alcohol
  • Family history
  • Previous heart conditions or surgery
  • Sleep apnea
  • Stress
  • Congenital heart defects
  • Heart attack
  • Overactive thyroid gland
  • Obesity



Given below are the risk factors that can increase the chances of this disease:

  • Cardiac Issues

People who are suffering from any heart disease such as congenital heart condition, heart failure or chronic artery disease have an increased chance of atrial fibrillation.

  • High Blood Pressure

High blood pressure increases the risk of cardiac issues because the blood pumps at a pressure that is higher than normal.

  • Chronic Health Conditions

Chronic conditions such as diabetes, hepatitis and renal issues can make a person more susceptible to acquire this disease.

  • Obesity

People who are obese are more prone to the onset of atrial fibrillation. That is why it is often advised to the patients that they should maintain a healthy weight.

  • Alcohol Consumption

Alcohol consumption also increases the chance of atrial fibrillation.

  • Family History or Genetics

Cardiac issues are more common in people who have a significant disease history of such medical conditions.

  • Thyroid Issues

People can also suffer from atrial fibrillation due to thyroid problems.

  • Age

 With age, the arteries tend to narrow down due to the deposition of fatty acids. This condition increases the risk of atrial fibrillation.

Complications of Atrial Fibrillation

There are several complications of atrial fibrillation. Some of them are:

  • Formation of blood clots
  • Chaotic heart rhythm can lead to the formation of blood clots in the arteries. The blood clot can detach and then travel to the brain. This can lead to stroke.
  • A person may also suffer from hypertension
  • Cardiac issues
  • Valvular heart conditions
  • Diabetes


Healthy lifestyle choices can prevent the onset of atrial fibrillation. Some other preventive strategies are as follows:

  • Consume a balanced and healthy diet
  • Quit smoking
  • Limit your alcohol intake
  • Keep the level of caffeine in check
  • Try to manage stress and deal with your anger issues
  • Engage more in physical activities
  • Make sure to maintain a healthy weight

Treatment of Tachycardia/Atrial Fibrillation | When to Consult a Doctor

Signs and symptoms are monitored and a physical exam is conducted. Other tests include:

  • Blood Tests
  • EEG
  • Echocardiogram
  • Holter Monitor
  • Event Recorder
  • Stress Test
  • Chest X-ray
