Why the study?
Does an algorithm based on the polarity of the QRS complex on five surface ECG leads reliably localize accessory pathways during sinus rhythm?
Does an algorithm based on the polarity of the QRS complex on five surface ECG leads reliably localize accessory pathways during sinus rhythm?
A simple algorithm using QRS polarity on five ECG leads offers a fast and reliable method for localizing accessory pathways.
May simplify accessory pathway localization via QRS polarity; leaves open prospective validation before routine use.
Analysis of the polarity of the QRS complex on five electrocardiographic leads provides an easy, fast and reliable way to localize accessory pathways during sinus rhythm.
