The two forms of ECG were analyzed by 2 cardiologists blinded to the method/posture of the participants. The following variables were examined:

Heart rate

Mean QRS vector

Mean P wave vector

Mean T wave vector

Mean QRS amplitude

QRS duration

QRS morphology

T wave polarity

PR interval

ST segment changes

Mean corrected QT interval (QTc)(Bazett's Formula)

All ECG variables were recorded using the computed ECG machine except for the QRS amplitude that was measured to the nearest 0.5 mm by calculating the sum of the highest positive and lowest negative deflection in the limbs and precordial leads with the help of magnifying glass and calipers, and the calibration was 1 mV = 10 mm. ST-T changes reported with positional changes were defined as a deviation (elevation or depression) of at least 1 mm in at least one lead.
