Deciphering hypertrophic cardiomyopathy with electrocardiography

Area of Science:

• Cardiology
• Medical Diagnostics
• Genetics

Background:

• Hypertrophic cardiomyopathy (HCM) assessment is complex, involving diagnosis confirmation, differentiation from non-sarcomeric phenocopies, and prognostication.
• Advanced diagnostics like genetic testing and imaging have improved understanding but lack universal availability and require expertise.
• Electrocardiography (ECG) is a readily available, rapid method essential for daily clinical evaluation of HCM patients.

Purpose of the Study:

• To review the role of electrocardiography in the comprehensive assessment of hypertrophic cardiomyopathy.
• To discuss the interpretation of ECG segments and their clinical implications in sarcomeric HCM.
• To highlight ECG's value in differentiating HCM from phenocopies and guiding patient management.

Main Methods:

• Systematic review of existing literature on electrocardiography in hypertrophic cardiomyopathy.
• Stepwise approach to interpreting ECG segments in the context of HCM.
• Analysis of clinical implications, differential diagnostic value, and prognostic impact of ECG findings.

Main Results:

• Specific electrocardiographic patterns provide significant diagnostic and prognostic information in hypertrophic cardiomyopathy.
• ECG is valuable in distinguishing sarcomeric HCM from non-sarcomeric phenocopies.
• Interpretation of ECG findings directly impacts clinical decision-making and patient management strategies.

Conclusions:

• Electrocardiography offers substantial diagnostic insights despite advancements in other modalities.
• The accessibility and interpretability of ECG ensure its continued integral role in hypertrophic cardiomyopathy assessment.
• ECG remains a cornerstone diagnostic tool for managing patients with hypertrophic cardiomyopathy.
