Inheritance of atrioventricular conduction time in Tokelau Islanders. 1986

L H Griggs, and C J Chapman, and D J McHaffie

The inheritance of A-V conduction time in Polynesians has been examined, using ECGs taken from the population of the Tokelau Islands. As has been demonstrated in other racial groups, A-V conduction time was influenced by sex, age, and heart rate. Complex segregation analysis provides evidence for a significant polygenic influence on A-V conduction, but no evidence for a major gene. Familial correlations and commingling analysis are in agreement with this conclusion. The heritability of A-V conduction time was 0.46. The hypothesis of Møller & Heiberg (1980a) that a major gene could be influencing A-V conduction, is not supported by these data.

D009520	New Zealand	A group of islands in the southwest Pacific. Its capital is Wellington. It was discovered by the Dutch explorer Abel Tasman in 1642 and circumnavigated by Cook in 1769. Colonized in 1840 by the New Zealand Company, it became a British crown colony in 1840 until 1907 when colonial status was terminated. New Zealand is a partly anglicized form of the original Dutch name Nieuw Zeeland, new sea land, possibly with reference to the Dutch province of Zeeland.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D001283	Atrioventricular Node	A small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus. It gives rise to the atrioventricular bundle of the conduction system of the heart.

D044468	Native Hawaiian or Other Pacific Islander	A person having origins in any of the original peoples of Hawaii, Guam, Samoa, or other Pacific Islands (https://www.federalregister.gov/documents/1997/10/30/97-28653/revisions-to-the-standards-for-the-classification-of-federal-data-on-race-and-ethnicity). In the United States it is used for classification of federal government data on race and ethnicity. Race and ethnicity terms are self-identified social construct and may include terms outdated and offensive in MeSH to assist users who are interested in retrieving comprehensive search results for studies such as in longitudinal studies.
