What is CIDG and CIDRNZ?
CIDG is a national network of specialist clinicians and scientists working to prevent sudden death due to inherited heart diseases. The Cardiac Inherited Disease Registry N.Z. (CIDRNZ) is an ethically approved national clinical registry designed to track registrants (individuals and families with known cardiac inherited disease) or cases of young sudden death typically 1 - 40 yrs (referred by the Forensic Pathologists/Coroner).
Each CIDG member has their own employing hospital or District Health Board. Aside from the coordinators based within ADHB, Waikato DHB and Capital and Coast DHB, CIDG does not receive individual funding, but works within existing clinical systems to facilitate clinical screening for families across the country.
Which conditions does CIDG deal with?
The commonest familial heart conditions are long QT syndrome (LQTS), Brugada syndrome (BRS) and Hypertrophic Cardiomyopathy (HCM). CIDG also coordinates nationally the family and genetic investigation for sudden unexpected natural deaths in 1-40 year olds. CIDG works closely with the national forensic and coronial services.
Who leads CIDG?
The national clinical leader is currently Dr Andrew Martin, Adult Heart Rhythm Specialist and he is supported by Dr Luciana Marcondes Paediatric Heart Rhythm Specialist, Dr Miriam Wheeler Adult Cardiomyopathy Specialist and Dr Ivor Gerber Adult Cardiomyopathy Specialist. Professor Jon Skinner, Children's Heart Rhythm Specialist, is taking a year long sabbatical leave (August 2019 - August 2020).
Which doctors belong to CIDG?
A group of clinicians from each region belong to CIDG, and these can be found on the CIDG website (www.cidg.org.nz). The majority are Cardiologists (heart doctors), Paediatricians, Geneticists and Pathologists.
Is this just for children?
No, CIDG facilitates family screening for all family members. The heart tests are usually performed locally, in your local hospital. Children sometimes have specialised heart tests at the Starship Hospital and test results can be copied and sent to other specialists for opinion.
Note: Please note below that some people are not available at all locations.
Anybody can refer to CIDG for advice, including the patients themselves. The coordinator will help them link to a local clinician with the necessary expertise. We hold a weekly case meeting and discuss cases from around New Zealand, to provide Specialist opinion and advice.
Pathologists dealing with a sudden death who require advice should call Dr. Skinner in the first instance via the hospital switch board, or relay a question via the Clinical Coordinator (email@example.com); information for review can be sent to our team support/administrator ( ).
Any clinician is welcome to phone or write for advice regarding their patients or families. It is almost always appropriate for the patient to be seen by a local specialist first.
Regarding written requests, please include as much detail about the family and the clinical presentation, including test results (particularly ECGs) necessary to permit an informed response.

The heart rate is controlled by a complex electrical system within the heart muscle which drives it to go faster when you exert yourself and slower when you rest. A number of conditions can affect the heart rate or rhythm. Heart rate simply refers to how fast the heart is… More
