МЕТОДОЛОГИЧЕСКИЕ ПОДХОДЫ К ИЗМЕРЕНИЮ И ОЦЕНКЕ ДЛИТЕЛЬНОСТИ ИНТЕРВАЛА QT СТАНДАРТНОЙ ЭЛЕКТРОКАРДИОГРАММЫ
Аннотация
Интерпретация каждой электрокардиограммы должна включать измерение и оценку интервала QT, как увеличение, так и уменьшение продолжительности которого ассоциировано с риском возникновения жизнеугрожающих желудочковых аритмий и внезапной сердечной смерти. В настоящей статье отражены методологические подходы к определению, измерению и оценке длительности интервала QT, рассмотрен характер его зависимости от пола, возраста и частоты сердечных сокращений у пациента, а также описан ряд показателей, вычисляемых на его основе. На основании проведенного анализа литературы сформулированы рекомендации по измерению и оценке интервала QT стандартной электрокардиограммы.
