What is the atrial and ventricular rate?
Is the rhythm regular or irregular?
If irregular, does it follow any repeatable pattern?
What is the axis?
ERAD often seen in VT but not SVT
What is the P wave amplitude, duration, morphology, and synchrony with QRS complex?
Is the P wave positive in Lead II
What is the QRS complex amplitude, duration, morphology?
What is the T wave amplitude, duration, morphology?
Is the T wave positive in Lead II
What is the length of PR and QT intervals?
Is there ST Elevation/Depression or Hyperacute T waves?
If yes, does it follow any anatomical pattern or is it diffuse?
Is there anything else abnormal about this ECG?
