Electrocardiography scar quantification correlates with scar size of hypertrophic cardiomyopathy seen by multidetector computed tomography

Abstract

The Selvester QRS score provides reliable quantification of myocardial fibrosis and was well correlated with MDCT in patients with HCM.

Detecting myocardial scar using electrocardiogram data and deep neural networks

“…Comparing our results with that of the other methods listed in Table 2, it must be taken into account that the underlying cohorts differ in size, structure and time of study. Considering the larger training sets used by Goovaerts et al (2019) and by Dima et al (2013) and the limited number of cases used by Chaudhry et al (2017) and Bignoto et al (2018), our results are similar. For a more substantiated comparison, the methods would have to be applied to the identical data, see Bengio and Grandvalet (2004).…”

Prediction of nonviable myocardium by ECG Q-Wave parameters: A 3.0 T cardiovascular magnetic resonance study

“…This study provides one of the first analyses using a 3 Tesla CMR and a simplified quantification method for QWA compared to the previously more complicated method for QWA quantification. 10 , 11 , 12 , 13 Our enrolled subjects had stable infarct size due to timing of CMR assessment in contrast to previous studies on acute myocardial infarctions. 14 Our results support the same direction found in prior studies revealing the correlation between global QWA and total scar volume.…”

Predictive role of Selvester QRS score in patients undergoing transcatheter aortic valve replacement

“…The amount of myocardial fibrosis is not a component of traditional surgical risk scores, and in the literature some studies have reported a correlation between the amount of fibrosis and mortality, both in other heart diseases 17,18,30 and also in AS 31 . Other publications have shown that the Selvester QRS score was well correlated with the estimation of fibrosis and cardiac imaging studies 32‐36 . Other publications have shown that use of the Selvester QRS score should be used with caution in patients with low LV ejection fraction and LBBB 37 .…”

“…31 Other publications have shown that the Selvester QRS score was well correlated with the estimation of fibrosis and cardiac imaging studies. [32][33][34][35][36] Other publications have shown that use of the Selvester QRS score should be used with caution in patients with low LV ejection fraction and LBBB. 37 In patients with low pretest probability of myocardial scar, Selvester QRS score requires greater clinical evidence.…”
