Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Electrocardiography

Background:

  • Left ventricular (LV) hypertrophy is a significant cardiovascular condition.
  • Accurate diagnosis of LV hypertrophy is crucial for patient management.
  • Current diagnostic methods may have limitations.

Purpose of the Study:

  • To identify and validate body surface potential map (BSPM) patterns indicative of left ventricular hypertrophy (LVH).
  • To assess the diagnostic performance of BSPM criteria for LVH.
  • To compare BSPM criteria with standard electrocardiographic lead criteria.

Main Methods:

  • Recorded body surface potential maps from 117 thoracic sites and 3 limb electrodes.
  • Analyzed PQRST waveform patterns in 173 normal subjects and 122 patients with LVH.

  • Identified discriminant LVH patterns by comparing patient maps to normal variability ranges.
  • Validated criteria on a new cohort of 169 subjects.

    • Main Results:

    • Specific patterns of excessive negative voltages in the anterior torso and reciprocal positive voltages in the upper right chest were identified.
    • ST-T wave features provided the best classification, followed by P wave features.
    • Combined ST-T and P wave features achieved 94% specificity and 88% sensitivity.
    • Validated criteria showed high specificity (93%) and sensitivity (90%) in a new cohort.

    Conclusions:

    • BSPM analysis reveals distinct, location-specific electrical patterns associated with LVH.
    • Discriminant criteria derived from BSPMs demonstrate high diagnostic accuracy for LVH.
    • BSPMs offer a promising non-invasive tool for diagnosing LVH, potentially outperforming standard lead criteria.
