 These last two definitions will be discussed in the topic [[P wave morphology]].
 Heart rhythms which are not sinus rhythm are [[arrhythmias]].
-==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?
 ==Sinus arrhythmias==

+Arrhythmias are discussed in the [[Arrhythmia]] chapter.
 If the heart rate exceeds 100 bpm, the [[Arrhythmias#Tachyarrhythmias|tachcyardia flow chart]] should be followed.
