By Adrian Monti for the Daily Mail. Ever since he took up competitive swimming aged nine, Aron Preece has been the epitome of a fit and healthy young man. Now 19, his slim but powerful frame is testament to the thousands of hours he has spent ploughing up and down the pool doing the sport he loves. But just over 18 months ago, Aron was diagnosed with a potentially fatal heart condition: Wolff-Parkinson-White WPW syndrome, an electrical fault that causes the heart to beat too fast.

Curious Kids: how does our heart beat?
Jump to content. Having bradycardia say "bray-dee-KAR-dee-uh" means that your heart beats very slowly. For most people, a heart rate of 60 to beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal.

Arrhythmias are abnormal heartbeats usually caused by an electrical "short circuit" in the heart. The heart normally beats in a consistent pattern, but an arrhythmia can make it beat too slowly, too quickly, or irregularly. This can cause the heart to pump inconsistently, leading to symptoms like fatigue, dizziness, and chest pain. Your heart has its own electrical system that sends electrical signals around the heart, telling it when to contract and pump blood around the body. The electrical signals start in a group of cells, called the sinus node , located in the right atrium.
