Respuesta :

A sinus rhythm is any cardiac rhythm in which depolarization of the cardiac muscle begins at the sinus node. It is characterized by the presence of correctly oriented P waves on the electrocardiogram (ECG).

What sinus rhythm?

  • Regular rhythm can be inferred from the RR interval's constancy.
  • Each complex begins with a normal P wave, indicating the impulse started in the SA node.
  • To get the heart rate, multiply the number of complexes in a 6 second strip by 10. The heart beats normally between 60 and 100 times per minute.
  • Elevation of the ST segment, which has nothing to do with the rhythm, is a symptom of myocardial ischemia.
  • The PR interval should be between 0.12 and 0.20 seconds, and the QRS duration should be less than 0.12 seconds.
  • The term "sinus rhythm" refers to the heart's typical beat, which is initiated at the SA node and propagated through the AV node, bundle of His, bundle branches, and Purkinje fibers.
