    This study establishes normal electrocardiogram (ECG) values for right chest leads (V3R-V7R) in healthy adults. Findings detail common QRS configurations and amplitudes, providing a reference for interpreting right ventricular function.

    Area of Science:

    • Cardiology
    • Electrocardiography
    • Cardiac Electrophysiology

    Background:

    • Right chest leads (V3R-V7R) are crucial for assessing right ventricular function.
    • Establishing normal electrocardiogram (ECG) parameters is essential for accurate diagnosis.
    • Previous data on normal right chest lead ECG findings in a healthy population is limited.

    Purpose of the Study:

    • To define normal QRS amplitudes and configurations in right chest leads (V3R-V7R) in a healthy adult cohort.
    • To present reference values for QRS duration, J-point, and ST-segment in these leads.
    • To investigate the impact of body position and respiration on right chest lead ECG parameters.

    Main Methods:

    • Recorded right chest leads (V3R-V7R) in 109 healthy individuals (40 women, 69 men; mean age 41 years).

  • Analyzed QRS configurations (rS, rSr', qS) and wave amplitudes.
  • Measured QRS duration, J-point, and ST-segment deviations at 40 and 80 msec post-QRS.
  • Evaluated ECGs in a 45-degree sitting position with deep inspiration and expiration.

    • Main Results:

    • High prevalence of rS or rSr' configurations in V3R (98%) and V4R (91%).
    • Secondary r waves increased in amplitude and frequency laterally, present in V7R (65%) with amplitudes not exceeding 5 mm.
    • qS configuration was most frequent in V6R (16%); r/s ratio > 1 was rare (8%) and never exceeded 1.5.
    • Body position and respiratory maneuvers did not significantly alter amplitudes.

    Conclusions:

    • Provides normative data for right chest lead ECG parameters in healthy adults.
    • Defines typical QRS morphologies and amplitude ranges for V3R-V7R.
    • These findings serve as a valuable reference for interpreting right ventricular abnormalities.
