BACKGROUND AND AIMS: Sudden cardiac death (SCD) is challenging to predict. Electrocardiogram (ECG) derived, heart rate corrected QT-interval (QTc) is used for SCD-risk assessment. QTc is preferably determined manually, but vendor-provided automatic results from ECG-recorders are convenient. Agreement between manual and automatic assessments is unclear for populations with aberrant QTc. We aimed to systematically assess pairwise agreement of automatic and manual QT-intervals and QTc. METHODS: A multi-center cohort enriching aberrant QTc comprised ECGs of healthy controls and Long-QT Syndrome (LQTS) patients...
