From the Guidelines
Research ideas within electrophysiology (EP) should prioritize investigating the role of wearable defibrillators as a therapeutic option in selected patients, as well as the feasibility of risk stratification with invasive electrophysiological study early after myocardial infarction, as highlighted in the 2015 ESC guidelines 1. These areas of research are crucial in advancing our understanding of cardiac arrhythmias and improving treatment outcomes, ultimately reducing morbidity, mortality, and enhancing quality of life. Some potential research directions include:
- Investigating the use of wearable defibrillators in patients with high-risk arrhythmias, such as those with inherited cardiomyopathies or arrhythmogenic disorders, to determine their efficacy and safety in preventing sudden cardiac death 1.
- Examining the role of invasive electrophysiological study in risk stratification after myocardial infarction, including the identification of patients at high risk for ventricular tachycardia or sudden cardiac death, and the development of personalized treatment strategies 1.
- Developing evidence-based interventions to reduce the psychosocial impact of arrhythmias on patients and families, and optimizing care and support for those at risk of sudden cardiac death, as emphasized in the 2015 ESC guidelines 1.
- Investigating the use of cardiac resynchronization therapy (CRT) in patients with atrial fibrillation, and the role of AV nodal ablation in this population, to improve treatment outcomes and reduce morbidity and mortality 1. These research areas address current knowledge gaps in electrophysiology and have the potential to directly impact clinical practice, improving arrhythmia management strategies and patient outcomes.
