MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html).

Accession:MP:0003233 term browser browse the term
Definition:increase in the length of time required for ventricular depolarization and repolarization to occur, usually as a result of increased repolarization time, and is measured from the beginning of the QRS complex to the end of the T wave
Comment:A prolonged QT interval is a risk factor for ventricular tachyarrhythmias and sudden death. It varies with heart rate and for clinical relevance requires a correction for this, giving the QTc.
Synonyms:exact_synonym: increased QT interval;   widened QT interval
 related_synonym: long QT syndrome
