This research aims to introduce and validate a new method for interpreting electrocardiographic leads based on spatial vectors and resultant electrical forces.
Used spatial vector analysis to study QRS vectors.
Analyzed variations in QRS and T contours across different leads.
Compared findings to existing methods of interpretation.
The new method reveals distinct differences in QRS vectors based on lead direction.
Illustration of the S1 S2 S3 pattern supports improved clarity in interpreting electrocardiographic data.
Demonstrates advantages over traditional pattern methods.
