Comparing 12-Leads: Discussion

Entry Img

This is the discussion for Comparing 12-Leads: Common Error or Common Disease? All of our readers were on the right track, and many were spot on! Sometimes, troubleshooting an ECG is more than just lead placement. In this case report, we had three 12-Lead ECG's, all featuring a similar pattern: inappropriate R-wave progression. Initially, when […]

Precordial Leads – The Transition, R-Wave Progression, R/S Ratio in Lead V1

Entry Img

Since we covered the first 6 leads of the 12 lead ECG in the 6-part tutorial on axis determination, a few words about the precordial leads might be in order. These are leads V1-V6, the unipolar leads that are placed directly on the patient’s chest. The heart is a 3 dimensional object, and calculating the […]

Infero-lateral MI therefore circumflex and not RV wall. Possibly posterior involvement but irrelevant.

Adenosine for sinus tachycardia: Try to avoid this!

Adenosine given for a narrow-complex tachycardia over 150
If things such as Sepsis, Drug Use, Medication issues, Anxiety, Pain, etc.. have been ruled out, and the rate is still >160 (or whatever number you use). How else do you determine S-Tach Vs. SVT? Does a 12 Lead Help (QRS Complexes facing different directions due to different pathways etc..) or a simple 4 Lead?…
