64 year old female CC: Trouble Breathing – Conclusion

Entry Img

Lots of great comments and it was good to see the depth of discussion on the appropriate treatment and transport for this patient! This is the conclusion to 64 year old female CC: Trouble Breathing. When we left off our crew was attending to an elderly female patient in respiratory extremis. Pulmonary edema was present […]

88 year old female CC: Chest pain – Conclusion

Entry Img

This is the conclusion to 88 year old male CC: Chest pain. Let's take another look at the 12-lead ECG. This ECG shows acute STEMI in the presence of left bundle branch block. It's also an excellent example of the value of using "excessive discordance" to identify acute STEMI in the presence of left bundle […]

58 year old female CC: Chest pain – Conclusion

Entry Img

Here’s the conclusion to the 58 year old female with chest pain and left bundle branch block. To refresh your memory here is the 12-lead ECG. And for those of you who requested lead V4R. This ECG meets all 3 of Sgarbossa’s criteria to identify acute STEMI in the presence of left bundle branch block. […]

Here’s another case study from an international reader who wishes to remain anonymous. Presenting Complaint – Chest Pain History of Present Complaint – 58 year old female, nil cardiac history, mild smoker, social drinker and overweight. Complaining of acute central chest pain @ rest.

Sgarbossa's Criteria – New Graphic

Entry Img

Here is a graphic I created to help explain Sgarbossa’s criteria for identifying acute myocardial infarction (AMI) in the presence of left bundle branch block (LBBB) or paced rhythm. In a previous article I showed this graphic which was created using PowerPoint. Here is a similar graphic I created this morning by cropping actual ECGs […]

Identifying STEMI in the presence of LBBB – Sgarbossa's Criteria – Part II

Entry Img

In Part I, we discussed Sgarbossa’s Criteria for identifying AMI in the presence of LBBB. We also talked about the “rule of appropriate T wave discordance” for bundle branch blocks and other forms of abnormal depolarization (like ventricular rhythms or paced rhythms). You will recall that I drew a distinction between a QRS complex’s main […]

Identifying STEMI in the presence of LBBB – Sgarbossa's Criteria – Part I

Entry Img

There has been a lot of discussion lately about identifying AMI in the presence of LBBB (see Dr. Bearemy’s “My Emergency Medicine Blog” here and a recent thread on the EKG Club). I’ve also been receiving a lot of emails offlist, so I think a full discussion is in order. In my recent post Who […]

63 year old male CC: Substernal Chest Pain – Discussion
[…] upright T waves is actually not representative of acute occlusion – for more on this, read this discussion on old versus “new” teaching on recognizing posterior MIs. We do not see ST elevation in aVR or V1 that would suggest a concomitant RV infarct, […]

Why give atropine at this time?

“Bad heartburn” – 82 y.o. female without chest pain.
In addition to the above treatment consensus (ASA, Plavix, judicious NTG, fentanyl, fluid bolus, right sided leads), I would absolutely transport this patient to a PCI centre. Culprit artery is the RCA (STE lead III > II) leading to AV nodal ischemia and junctional bradycardia. In addition to the above treatment I would give 0.5…

“Bad heartburn” – 82 y.o. female without chest pain.
Not much to add but my 2 cents...I'd definitely be careful with the nitro, not saying withhold it completely but absolutely use some common sense. I'd have to say probably RCA occlusion, and catch team needs to be activated for a stemi alert immediately. Treat it like a stemi until proven otherwise. If it walks…

The option was indeed turned on! As for non-CP presentations of ACS, I absolutely believe that these warrant the same level of urgency as the "typical" presentations. Both men and women, young and old, all commonly present without classic chest pain. Besides, how much difference is there between "burning in the epigastrium," and "pain in…
