| Definitions |
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.[url:http://purl.obolibrary.org/obo/MP_0003233] 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 [url:http://purl.obolibrary.org/obo/MP_0003233] |
