Phase N/A

Study Objective: Researchers aim to understand why some hearts experience ventricular arrhythmias, which are unusual heart rhythms in the lower chambers. They will study the heart's electrical signals to find problem areas that might cause these arrhythmias. This research may improve results for those undergoing ventricular tachycardia (VT) ablation, a procedure to treat fast heartbeats.

Current Challenges: VT ablation is the main treatment for those whose conditions don't improve with medication. However, it often doesn't work well because it’s hard to find key areas of heart muscle causing VT. Newer methods to map the heart have not significantly increased success rates. The study will use a special tool, the MAP catheter, to better detect areas critical for treating VT. This catheter records electrical activity without disrupting standard treatment.

  • Participation might involve using a special catheter during a typical VT ablation.
  • Eligible participants must have a specific heart condition and an implantable defibrillator.
  • Exclusion criteria include certain heart conditions and recent heart surgeries.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
