11. ISE/ISHNE expert consensus statement on the ECG diagnosis of left ventricular hypertrophy: The change of the paradigm.

Abstract

The ECG diagnosis of LVH is predominantly based on the QRS voltage criteria. The classical paradigm postulates that the increased left ventricular mass generates a stronger electrical field, increasing the leftward and posterior QRS forces, reflected in the augmented QRS amplitude. However, the low sensitivity of voltage criteria has been repeatedly documented. We discuss possible reasons for this shortcoming and proposal of a new paradigm. The theoretical background for voltage measured at the body surface is defined by the solid angle theorem, which relates the measured voltage to spatial and non‐spatial determinants. The spatial determinants are represented by the extent of the activation front and the distance of the recording electrodes. The non‐spatial determinants comprise electrical characteristics of the myocardium, which are comparatively neglected in the interpretation of the QRS patterns. Various clinical conditions are associated with LVH. These conditions produce considerable diversity of electrical properties alterations thereby modifying the resultant QRS patterns. The spectrum of QRS patterns observed in LVH patients is quite broad, including also left axis deviation, left anterior fascicular block, incomplete and complete left bundle branch blocks, Q waves, and fragmented QRS. Importantly, the QRS complex can be within normal limits. The new paradigm stresses the electrophysiological background in interpreting QRS changes, i.e., the effect of the non‐spatial determinants. This postulates that the role of ECG is not to estimate LV size in LVH, but to understand and decode the underlying electrical processes, which are crucial in relation to cardiovascular risk assessment.

12. Moving from a training project to a real international project: an experience with an on-line mentorship model.

Abstract

The International Research Interdisciplinary School (IRIS) program is a training for young researchers with a biomedical background who are interested in acquiring the methodological knowledge and experience in preparing a study protocol for a project. The IRIS program is an outcome-oriented problem-solving workshop designed to promote team collaboration. The paper describes the process of moving from the training project proposal into a real-life research project. It compares the initial proposal and its assumptions with the reality of writing a research protocol and management of the study. It also reflects on the obstacles met at each stage of the project (protocol preparation / team recruitment / data collection and analysis / manuscript writing) and strategies to overcome difficulties regarding conducting the study inspired by the training project proposal.

48. Changing the diagnostic paradigm of the ECG diagnosis of left ventricular hypertrophy.

Abstract

This document is an editorial discussing the diagnostic paradigm of the electrocardiographic (ECG) diagnosis of left ventricular hypertrophy (LVH). The author highlights the limitations of using ECG criteria to estimate LV mass compared to imaging methods like echocardiography and cardiac magnetic resonance. The editorial emphasizes the unique diagnostic strength of ECG in recording the electrical phenomena of the heart on the body surface. It also discusses the complex rebuilding of the left ventricle at various levels and the need to better understand the spectrum of QRS patterns associated with LVH. The document suggests that the new paradigm of ECG diagnosis of LVH opens up exciting opportunities for clinical and basic research. [Extracted from the article]
