Implication

Provides reference ranges for orthogonal ECG/VCG parameters in men; leaves open prospective validation before clinical adoption.

Structured PICO

What are the normal ranges for corrected orthogonal electrocardiogram and vectorcardiogram measurements in normal men?

Population

510 normal male subjects, age ranging from 19 to 84 years.

Intervention

Corrected orthogonal electrocardiogram and vectorcardiogram (Frank Lead System)

Outcome

Normal ranges for instantaneous vectors of the QRS complex, ST segment, and T wave, as well as time integrals, polar vectors, and Eigenvectors for P, QRS, and Tsurrogate

This study establishes normal reference ranges for corrected orthogonal electrocardiogram and vectorcardiogram measurements in healthy men.
