The QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ 0,12 seconds (120 milliseconds) then the QRS complex is abnormally wide (broad). This is very common and a …

How to Calculate the Heart Axis - My EKG

https://en.my-ekg.com/how-read-ekg/heart-axis.html

How? Very simple. We check whether the QRS deflection in leads I and aVF are positive or negative. With this we will be able to determine if the heart axis is normal or a deviation is present. 1. If the …
