==Interpretation of the heart rhythm==
==Interpretation of the heart rhythm==
 
A good stepwise approach to interprete the heart rhythm is to follow these steps:
# '''Cherchez le P''', French for ''find the P waves''.
** Do you see P waves? Leads II and V1 are often most suitable to find P waves.
** What is the [[rate]] of the P waves?
** What is the [[P wave morphology]]?
# What is the relationship between P waves and QRS complexes?
** Is every P wave followed by a QRS complex? And every QRS preceded by a P wave? In short: is there a 1:1 relation between P waves and QRS complexes?
** What is the [[Conduction|PR interval]] and does it change?
# What is the ventricular [[heart rate]]?
# What is the [[QRS morphology]]?
# What is the clinical setting?
