What is the electrocardiographic and vectorcardiographic diagnosis

How to explain the aberrant location of ventricular depolarization in a patient with normal left ventricular wall location, size, wall thickness,and left ventricular ejection fraction?

How to explain the extreme low voltage of the QRS complexes in the frontal plane?

Why is the transition R-wave progression (isodiphasic R/S ratio) not present across the unipolar precordial leads?

What is the proper approach and risk stratification?
