Physical Examination as a Helpful Aid in Decision-Making in Challenging ECGs

Dr. Smith's ECG Blog

While the initial impression might not immediately suggest ventricular tachycardia (VT), a closer examination raises suspicion. Additionally, the qR morphology, particularly in a patient with right bundle branch block (RBBB) type wide QRS complex tachycardia (WQCT), lends further support for VT. What is the rhythm?

In that study commonest ECG abnormalites were QTc prolongation followed by brady/tachycardia and then ST segment deviations [3]. 2009 Nov;40(11):3478-84. Epub 2009 Aug 27. But the number of persons with lobar hemorrhage in that study was only 17%. doi: 10.1161/STROKEAHA.109.556753. 109.556753.

Precordial ST depression. What is the diagnosis?

Dr. Smith's ECG Blog

Notice there is tachycardia. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. In this case, the patient had failed to take his atenolol in the AM and was having reflex tachycardia in addition to ACS. Blackwell Publishing 2009. BP was 160/100. younger smoker).

What do you think of this "Ventricular Bigeminy"?

Dr. Smith's ECG Blog

Another way that WPW can be concealed is in the very rare (~15% of all WPW patients) retrograde-only conduction, in which the accessory pathway ONLY allows retrograde conduction, which obviously wouldn't show a delta wave on sinus EKG but still predisposes the patient to re-entry tachycardias.

From The Vault: RBBB

EMS 12-Lead

Original publication date July, 2009. If this was a tachycardia at a rate of 150, it might appear to be a narrow complex tachycardia, when in fact, it would be a wide complex tachycardia! Concept Review How do you identify right bundle branch block (RBBB) on the 12 lead ECG? In other words, are the QRS complexes “wide”?

A young lady with wide complex tachycardia. My first time actually making this diagnosis de novo in real life in the ED!

Dr. Smith's ECG Blog

She was awake, alert, well perfused, with normal mental status and overall unremarkable physical exam except for a regular tachycardia, possible rales at both bases, some mild RUQ abdominal tenderness. Thus, I believe it is a regular, monomorphic, wide complex tachycardia. J Electrocardiol, 42 (2009), pp. What is the Diagnosis?
