Atrial Fibrillation

What is atrial fibrillation?

Atrial fibrillation is a condition in which your heart's rhythm becomes irregular. Rather than beating in a constant, regulated manner, a heart with atrial fibrillation (AFib) has both long and short gaps between beats.

AFib is due to something going wrong with the electrical system that controls your heart. Instead of beating strongly, the atria (upper chambers) tremble, so blood can't move into the heart's ventricles as efficiently as it should.

Consequently, the atria beat too fast, and the lower ventricles beat too slowly, resulting in the irregularities present when you have atrial fibrillation. It's important to visit Indus Cardiology if you develop an irregular heartbeat to reduce your risk of stroke or heart attack.

What might cause atrial fibrillation?

Some patients have atrial fibrillation without a clear cause, but the most likely triggers are:

  • Congenital heart defects
  • Heart attacks
  • Thyroid disease
  • Obesity
  • Hypertension
  • Coronary artery disease
  • Sleep apnea
  • Stimulants, such as caffeine and tobacco
  • Certain medications

In some cases, atrial fibrillation develops when there are extra electrical currents in the pulmonary veins in your lungs.

As well as the irregular heartbeat, atrial fibrillation can make you feel weak and short of breath, and you might develop chronic fatigue. Chest pain is also a potential symptom, and you could experience dizziness or lightheadedness, confusion, and possibly fainting spells.

What treatment might I need for atrial fibrillation?

Potential treatments for atrial fibrillation include:


Beta blockers and similar drugs like calcium channel blockers help to slow your heart rate down. Anticoagulants — medicines that thin your blood — might be necessary to lower the risk of blood clots forming and giving rise to a heart attack or stroke.

Minimally invasive procedures

If your atrial fibrillation is a result of problems with your lung veins, pulmonary vein isolation ablation (PVA or PVI ablation) can help. This procedure destroys the faulty cells causing the AFib, which helps to restore a normal heart rhythm.

A similar procedure is atrioventricular (AV) node ablation, which destroys faulty cells in your heart. Alternatively, you might need an implantable device like a pacemaker to help regulate your heartbeat.

As well as these interventions, you can also reduce the severity of your atrial fibrillation by managing any underlying conditions more effectively.

Prompt treatment from the expert team at Indus Cardiology can minimize the effects of atrial fibrillation and lead a healthier life. Call today to find out more or book an appointment online.
