  • The 2009 electrocardiographic Selvester QRS score for LBBB (2009 LBSS) is prognostic in CRT-patients. Previous studies show limited diagnostic performance in detecting and quantifying left ventricular (LV) scar determined by cardiovascular magnetic resonance imaging (CMR). We aimed to develop an improved method for ECG detection of scar using a large and broadly selected dataset of patients with LBBB.  The 2009 LBSS does not accurately detect or quantify CMR scar. Extensive comparison of ECG and CMR identified a single ECG measure (lead I R/S amplitude ratio <12) as predictive of scar presence and poor LV function. Validation of the latter finding in an independent test set is needed.

    JT interval: What does this interval mean?
    by Wojciech Zareba, Scott McNitt, Slava Polonsky, Jean-Philippe Couderc

    The JTp interval gained interest as a marker differentiating effects of drugs on cardiac ion channels. For JTp interval, both the beginning – identification of J point and identification of T wave end remains the subject of substantial variability. We aimed to analyze diagnostic and prognostic performance of JTp interval in the International LQTS Registry data. ECGs from 804 gene carriers and 1139 non-carriers from LQT1 families, 735 carriers and 1145 non-carriers from LQT2 families, and 238 carriers and 554 non-carriers from LQT3 families were evaluated. The diagnostic performance of JTpc was similar to QTc in LQT1 and LQT3 patients but inferior in LQT2 patients, whereas repolarization duration in general had limited diagnostic performance in LQT3 patients. The prognostic significance for predicting cardiac events in LQT1 and LQT2 patients was similar for JTpc and QTc. In LQT3 patients, JTpc fails to be associated with arrhythmic events.

    Gender equity imbalance in electrocardiology: A call to action
    by E Clarke Whalen, G Xu, I Cygankiewicz, L Bacharova, W Zareba, JS Steinberg, LG Tereshchenko, A Baranchuk

    Gender equality in electrocardiology: a work in progress. As more women are entering medicine, gender equality has become an area of great attention. Despite the increasing number of women becoming doctors, cardiology remains a male-dominated profession. The International Society of Electrocardiology and International Society of Holter and Noninvasive Electrocardiology have recently looked at the representation of women within the subspeciality of electrocardiology. A recent analysis suggests that there may be a significant gender imbalance with respect to both leadership and involvement in research in the field. Creating gender diversity in medicine, including electrocardiology, is vital as it allows for access to the full pool of talent in both genders, which will help to generate the highest quality clinicians, educators, and researchers. Closing the gender gap in electrocardiology is an important issue and will be an area of focus for the International Society of Electrocardiology in the future.
