ST elevation

Brugada Pattern

Tue, 06/06/2017 - 14:41 -- Dawn

This patient is a 50-year-old man with a history of epilepsy and early dementia. He had a VP shunt placed in the hospital and was then discharged home.  He became extremely weak, which was not characteristic of him, and 911 was called.  He was transported to the hospital uneventfully. He was found to be afebrile.

Acute M.I. In Patient With Pacemaker

Wed, 01/04/2017 - 21:07 -- Dawn

This ECG is taken from an elderly man who has a history of complete heart block and AV sequential pacemaker.  On the day of this ECG, he presented to the Emergency Department with chest pain and shortness of breath. His vital signs were stable and within normal limits.  We do not have information about his treatment or outcome. 

Teaching Series: Acute Anterior Wall M.I.

Sun, 06/26/2016 - 15:33 -- Dawn

Intermittent chest pain.     This series of three ECG were taken from a 41-year-old man with a two-week history of intermittent chest pain.  At the time of the first ECG, 12:05 pm, he was pain-free.  We see a sinus tachycardia at 102 bpm, and has just come under the care of paramedics. There is a very subtle ST sagging and T wave inversion in Lead III, and no other ST changes. He had an uneventful trip to the hospital.

Inferior Wall M.I. With Subtle ST Elevation

Mon, 01/18/2016 - 00:24 -- Dawn

This ECG is a good example of an inferior wall M.I. that was confirmed and treated in the cath lab.

The ST segments are elevated in Leads II, III, and aVF, but the amount of elevation may look subtle to some.   When the amount of elevation seems small, what other signs can help us recognize acute ST-elevation M.I.? 

Anterior Wall M.I.

Sun, 07/26/2015 - 13:10 -- Dawn

This is a very interesting ECG taken from an acute M.I. patient.  Your basic level students will be able to appreciate the ST elevation in V1 through V3. Although the elevations are not very high, there are plenty of other abnormalities that point to acute STEMI: the ST segments are flat and there are marked ischemic T waves in the lateral leads: V4 through V6 and I and aVL.  The patient was suffering an acute episode of chest pain.

Second-Degree AV Block, Type I

Sat, 06/13/2015 - 22:07 -- Dawn

This ECG is from an 80-year-old woman who had an acute inferior wall M.I. with a second-degree AV block.
 
Some people incorrectly call ALL second-degree AV blocks that are conducting 2:1 "Type II".  This is incorrect, as Mobitz Type I can also conduct with a 2:1 ratio.  The progressive prolongation of the PR interval will not be seen with a 2:1 conduction ratio, because there are not two PR intervals in a row.
