AI-ECG Accessory Pathway Localisation Study

This study is looking at how well a special computer program, called Artificial Intelligence (AI), can find the exact spot of an electrical problem in the heart. This problem is called an 'accessory pathway' and can cause the heart to beat too fast or irregularly. The AI program looks at a standard heart tracing (ECG) to try and locate this pathway. Researchers are comparing the AI's findings with the actual spot doctors find and fix during a heart procedure. This helps them see if the AI program is accurate in a real-world setting. If successful, this could one day help doctors plan treatments more effectively for people with this heart condition.

Accessory Pathway Artifical Intelligence ECG

What is this study about?

This study is investigating a new way to help doctors locate a specific type of electrical problem in the heart. Sometimes, people have an extra electrical connection, known as an 'accessory pathway', which can cause their heart to beat too quickly or irregularly. When this happens, doctors often recommend a procedure called an 'electrophysiology study' (EPS) to find and fix this pathway.

Before this procedure, a routine heart tracing called an electrocardiogram (ECG) is often taken. This study is testing a special computer program, using Artificial Intelligence (AI), that can analyse these ECGs. The goal is for this AI program to accurately identify where the accessory pathway is located in the heart.

The study works by taking ECG information from people who are already having an EPS procedure. The AI program will then try to predict where the accessory pathway is. After the procedure, doctors will compare the AI's prediction with where they actually found and successfully treated the pathway. This comparison will help the researchers understand how precise and reliable the AI program is. If the AI is shown to be accurate, it could potentially help doctors better understand a patient's condition and plan their treatment more effectively in the future, possibly making procedures quicker or safer.

Key takeaways

This study evaluates an AI computer program for locating heart problems.
It aims to find an 'accessory pathway', an extra electrical connection in the heart.
The AI uses your routine heart tracing (ECG) to make its prediction.
Your current medical care will not be affected or changed by this study.
Participation involves no extra tests or appointments for you.

Who may be eligible?

To be part of this study, you would need to be scheduled for a special heart procedure called an 'electrophysiology study' (EPS). This procedure is typically done to fix an extra electrical connection in your heart that can cause fast or irregular heartbeats.

You would also need to show signs of this extra electrical connection on your heart tracing (ECG) at some point before your procedure. The study is open to both men and women, aged between 13 and 100 years old, who are able to understand and agree to take part.

However, you wouldn't be able to join if you're unable to give your consent, are outside the age range, or if doctors already know exactly where your accessory pathway is from a previous heart study.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

Are you scheduled for an 'electrophysiology study' (EPS) heart procedure?
Has your ECG (heart tracing) shown signs of an extra electrical connection?
Are you between 13 and 100 years old?
Can you understand and agree to take part in the study?

Answer every question to see your result.

What does participation involve?

Taking part in this study is very straightforward, as it uses information that your doctors will already be collecting as part of your usual care. You won't need to have any extra tests, appointments, or take any additional medication. The researchers will simply use the ECG information taken before your heart procedure (electrophysiology study) and compare it with the details of where your doctors successfully treated the electrical pathway during that procedure. There's no extra time commitment for you beyond your planned medical care, and no follow-up specifically for the study. The total duration of your participation only involves the collection of this existing information.

Potential risks and benefits

There are no direct personal benefits for participating in this study as it involves reviewing existing medical information rather than providing new treatment. Similarly, there are no additional risks to you from taking part, as it doesn't involve any extra tests, procedures, or changes to your care. Your main benefit would be contributing to medical knowledge, which could help future patients with similar heart conditions. You are always free to decide not to participate or to withdraw your consent at any time, and this will not affect your medical care in any way.

Common questions

What is an 'accessory pathway'?

It's an extra electrical connection in the heart that can sometimes cause the heart to beat too fast or irregularly.

What is an 'ECG'?

An ECG is a common and harmless test that records the electrical activity of your heart, often called a heart tracing.

What is 'AI' in this study?

AI, or Artificial Intelligence, is a clever computer program trying to learn and identify patterns in your ECG to find the problem spot.

Will taking part change my medical treatment?

No, taking part will not change the medical care or treatment you receive for your heart condition.

Do I have to do anything extra?

No, you don't need to do anything extra for this study. Researchers will use information already collected for your care.
