Plain-language summary

The Hearts in Rhythm Organization (HiRO) is a national network of Canadian researchers/clinicians, working towards a better understanding of the rare genetic causes of sudden cardiac death (SCD). Canadian adult and pediatric electrophysiology centres across Canada work together to gather data and bio sample in a national data registry and bio bank hoping to improve the detection and treatment of inherited heart rhythm disorders to prevent sudden death.

Inclusion Criteria: * All Canadian patients referred for cardiac investigations related to inherited heart rhythm (IHR) conditions will be invited to participate if they meet the following criteria: * They understand the registry/bio bank purpose, potential risks and willingly sign consent * Recognized genetic syndromes; Long QT syndrome (LQT), Short QT Syndrome (SQT), catecholaminergic polymorphic ventricular tachycardia (CPVT), Brugada (BrS), Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), Familial Cardiac Conduction Disease (FCCD). * Deceased cases of SCD, suspicious for an inherited heart rhythm condition. Included with signed consent from next of kin (NOK). * IHR patients referred for risk of SCD enrolled (includes first degree and second degree relatives) SCD syndromes seen in heart rhythm clinics; Unexplained cardiac arrest (UCA), Early Repolarization (ER), Idiopathic Ventricular Fibrillation (IVF), Short Coupled IVF (SCIF), Polymorphic Ventricular Tachycardia Not Otherwise Diagnosed (PMVT, NYD), Sudden Arrhythmic Death Syndromes (SADS) that are SCD cases with negative autopsy results. * Mendelian cardiomyopathies (hypertrophic cardiomyopathy (HCM), Mendelian Dilated Cardiomyopathy (DCM) including Lamin and Phosopholambin (LMNA, \& PLN), and Left Ventricular Non -Compaction (LVNC). \*\*Must have either a probable or definite clinical diagnosis, first degree relative (FDR) with a known diagnosis, gene carrier (disease causing or likely disease c…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
