Plain-English translation of NCT03880708 on ClinicalTrials.gov ↗ · Source last updated · Translation generated · How we translate trials
This is an observational study — meaning researchers aren't testing a new medication, but rather collecting real-world information from patients with inherited heart rhythm disorders like Brugada syndrome, Long QT syndrome, and similar conditions. Researchers will review your medical records, ask about your health history, and collect blood samples to study how genetic changes relate to your symptoms and how doctors can better predict and treat these conditions.
In China, doctors don't yet have clear information about how common these inherited heart rhythm disorders are, what factors make them more dangerous, or the best ways to prevent serious events. This study aims to build a better understanding so that treatment can be more personalized and effective for future patients.

At enrollment, you'll meet with trained staff who will ask questions about your medical history, review your medical records, and take a blood sample for genetic testing. After that, you'll have follow-up visits every 6 months where the research team will check in on your heart rhythm, any medications you're taking, and any health events you've experienced. The study aims to track your health over time to better understand your condition.
