This leaves us with the usual differential diagnosis for this rhythm presentation ( as per ECG Blog #361 ) ==> We need to consider i ) VT until proven otherwise: ii ) SVT with either preexisting BBB or aberrant conduction; — or , iii ) Something else ( ie, WPW, hyperkalemia, some other toxicity, etc. ). What Kind of Conduction Defect?

The ECG in Figure-1 was obtained from a middle-aged man with known hypertension — who presented to the ED ( E mergency D epartment ) for CP ( C hest P ain ) over the preceding 2-3 days. For more regarding ECG criteria for LVH — See the ADDENDUM below and/or ECG Blog #73 and ECG Blog #245. Should you activate the cath lab?

NOTE: For more on ECG recognition of RVH and/or pulmonary hypertension ( re the qR pattern in lead V1 ) — See ECG Blog #234 and Blog #248. This could have been an optimal time to try a Lewis Lead — which sometimes reveals atrial activity not evident with standard lead placement ( See ECG Blog #223 ).

The ECG in Figure-1 was obtained from a middle-aged woman — who presented with low back pain, shortness of breath and marked hypertension — but no CP ( C hest P ain ). Today's patient is a middle-aged woman who presented with low back pain, shortness of breath and marked hypertension — but no chest pain. The KEY lies in the history.

== P lease N OTE : After today — No new ECG Blog posts for 2- to -3 weeks. — I will also not be prompt in replying to emails. == All material on this ECG Blog site remains open! IF you scroll down a little on the right-hand column of this blog — You'll see a lot of icons. Figure-1: The initial ECG in today's case.

She had a history of hypertension, and was on medication for this — but she was otherwise healthy. Contrast today's rhythm with true ventricular bigeminy — that was seen in ECG Blog #343 ). Contrast today's rhythm with true alternating bundle branch block — that was seen in ECG Blog #306 ). Is this Ventricular Bigeminy?

In this ECG Cases blog we look at 10 patients with shortness of breath, and discuss how the ECG can be used to help diagnose cardiac, respiratory and metabolic emergencies. For RV strain, acute vs chronic, we should look for signs of acute RV strain and chronic pulmonary hypertension.
