Sinus Tachycardia
A new Sinus Tachycardia Section has been added to the ECG Analysis Module on www.richacls.com. Below are some of the Key Learning Points (KLP)
Sinus Tachycardia: Introduction
- Sinus tachycardia is defined as a sinus rhythm with a rate greater than 100 beats/min.
- Sinus tachycardia differs from other tachycardias in that it is the body’s response to an underlying issue.
- Since Sinus tachycardia is a symptom of an issue, it is the underlying issue which needs to be treated, not the rhythm.
Terminology, Supraventricular
- Supraventricular is used to describe any rhythm which originates from above the ventricles, specifically abovethe bifurcation of the bundle of HIS(a.).
- Supraventricular Tachycardia is used to describe the various supraventricular rhythms with rates above 100 beatsper minute
Characteristics
- Sinus Tachycardia usually begins and ends gradually.
- The rhythm is regular.
- The heart rate is above 100bpm (adults).
- P wave before each QRS.
- All p waves are the same shape.
- PR Interval 0.12-0.20 sec.
- QRS duration equal to or less than .10 seconds.
I hate to be one of those kind of people but shouldn’t the following:
“Supraventricular Tachycardia is used to describe the various supraventricular rhythms with rates above 100 beats per minute”
Be “rates above 150 beats per minute”?
Thanks for the site, Really enjoying it!

“I hate to be one of those kind of people but shouldn’t the following” this questioning is a quality which will allow you and others around you to learn; don’t lose it.
Supraventricular Tachycardia, which you probably know, is a general term used to describe the many rhythms arising from above the ventricles i.e.: Sinus rhythm, Atrial fibrillation, Atrial Flutter. Any rhythm above 100 beats/min is considered tachycardic and if it is coming from above the ventricles it is considered Supraventricular Tachycardia. During the research for our online ECG class it became apparent there is no one source everyone uses for EKG standards. The standards we used are from the American Heart Association whenever possible. One good way to search for EKG information is to Google “AHA xxxxxxx” and it will often take you to some AHA information.
Good Luck to you in your career.
