The Trouble with Sinus Tachycardia

Entry Img

  Sometimes recognizing sinus tachycardia can give us fits. What? Sinus tachycardia? One of the most basic rhythms? The discussion that follows will highlight some of the difficulties sinus tach can present at high rates. The pitfalls of using the generalized term "SVT" will also be discussed. This discussion is not meant to imply that […]

Snapshot Discussion: 32 year old Male–Chest Discomfort

Entry Img

Here is the discussion for the Snapshot Case: 32 year old male–Chest Discomfort. Sorry for the delay. If you recall, we have a young patient, a 32 year old male, with a heart rate too rapid to count. He is alert and oriented, and has a good pressure (126/70). He has been in the following […]

Narrow complex tachycardias – Part III

Documenting the heart’s response to adenosine Let’s look at some different cases where adenosine was used. Rather than give you all the details about the age, gender, chief complaint, and vital signs, I’m just going to show you the rhythm strips. Right now I’m only concerned with how the heart behaves during the administration adenosine. […]

Narrow complex tachycardias – Part II

Entry Img

Here’s a call that was very well executed. The patient was a 35 year old Hispanic female; walk-in patient at a volunteer clinic. Through an interpreter it was learned that the patient was complaining of palpitations and slight chest discomfort. The onset was sudden. The medical history was significant for “arrhythmias”. No medications. Skin: warm […]

Narrow complex tachycardias – Part I

Entry Img

I've come to dislike the term "SVT" (supraventricular tachycardia). In the first place, it's not an arrhythmia. It's an umbrella term that covers a group of arrhythmias which require the AV node for their maintenance. Most importantly, it includes sinus tachycardia! For some reason, this is a difficult concept for many clinicians to grasp, partly […]

The role of 12 lead ECG in Pediatric Pulmonary Hypertension
Thanks for writing Tyler. They are the same thing. Strain pattern is just the result of increased pressures against the ventricles which alters the way repolarization occurs from epicardium to endocardium. Similar to stepping on a puddle of water. Your show spreads the water away from the area of pressure. The ST segment is slightly…

Can you explain how these ST segment and T wave changes can be differentiated from right strain pattern?
