Teaching Series - Tachycardia and Left Anterior Fascicular Block

This series of three ECGs is from a 60-year-old man who was brought to the Emergency Department after being involved in a motor vehicle accident.  No injuries were found, but the patient was severely intoxicated by alcohol consumption.  He was conscious but agitated.

ECG Basics: Sinus Tachycardia vs. PSVT

Thu, 04/21/2016 - 00:13 -- Dawn

Narrow-complex tachycardias can be very confusing to students of basic-level ECG.  There are very many rhythms that fall into the broad category of narrow-complex tachycardia.  We usually further divide them into sinus tachycardia and other "supraventricular tachycardias".  The basic student will want to make this distinction, as well as be able to differentiate atrial fib and atrial flutter from the other SVTs.  The more advanced student will want to go into more detail about which mechanism for supraventricular tachycardia is present.

ECG Basics: Supraventricular Tachycardia

Fri, 05/17/2013 - 22:20 -- Dawn

This strip is from a patient who experienced a sudden onset of palpitations and rapid pulse while at rest.  It shows a narrow-complex tachycardia, specifically a paroxysmal supraventricular tachycardia.  The subject of supraventricular tachycardias is a fascinating one, and is covered extensively throughout this website.  The mechanisms of SVT are many, and can be complex for the beginning student to understand.  Search the search terms on the left side of the page for entries from ASK the EXPERT and JASON's BLOG for more advanced information about SVT.
