A
The selection of an electrocardiographic monitoring lead is not a decision to be made casually or according to habit.The monitoring lead should be chosen with consideration of the patient's clinical condition and recent clinical history.Lead II is recommended for monitoring of atrial dysrhythmias and would be appropriate in this case as due to inferior wall injuries.Lead V1 is recommended for monitoring of ventricular dysrhythmias.Leads I and aVF are selected to detect a sudden change in ventricular axis.
