Atrial fibrillation is the most common heart rhythm problem in the UK.

It can cause fatigue and dizziness and increases the risk of stroke and heart failure.

Traditional procedures used to treat the condition can come with complications including nerve damage.

Doctors at St George’s Hospital have been using a new technique called Pulsed Field Ablation.

This uses thousands of electrical pulses every second to silence areas of the heart causing abnormal signals.

Several hundred patients have been treated at George’s through this method under general anaesthetic in the past three years.

The hospital says it has cut waiting lists by around 20%.
