Let’s talk about sinus rhythm

The term “sinus rhythm” is used when the rhythm originates in the sinus node at atrial rate in between 60-100 bpm.  

Criteria

  • Normal P wave with constant morphology.  
  • Regular atrial rate in between 60-100 bpm.  
  • P wave is upright in lead II. 

Graphic explanation.

 

Another example. 

There are two exceptions where P wave can be negative in lead II and may still sinus originin:

  • Dextrocardia 
  • Limb lead misplacement.

Note: It is important to clarify that sinus rhythm can be present in the setting of 2:1 AV block, third degree or complete AV block, etc.
