Medical Assistant Prep / Unit 23 MAS 562 short lesson, about 20 seconds
Normal Sinus Rhythm
Captions available
The idea
Normal sinus rhythm means the heartbeat starts in the SA node and follows the normal pathway.
In practice
The rhythm is regular, a P wave comes before every QRS complex, and the rate is within the normal range.
Where people slip
A normal-looking tracing does not override a patient's symptoms; report symptoms regardless.
