LAD occlusion in the setting of paced rhythm by Stephen Smith Posted Wed 22 Dec 2010 11:47am An 80 yo male presented with chest pain. There is clearly a ventricular paced rhythm. Normally in a paced rhythm, the QRS is all negative from V1-V6 because the pacing wire is in the apex of the RV and thus all depolarization goes away from the apex. . In the above ECG, the QRS in V2 is positive and all others are negative, as in the ... Read on »

Discordant ST-Segment Elevation in LBBB or Paced Rhythm by Adam THOMPSON Posted Wed 27 Jan 2010 8:23am If you've been following the Prehospital 12-Lead ECG blog for a while, you know that I'm advocate of using Sgarbossa's criteria to help identify acute STEMI in the presence of left bundle branch block (LBBB) or paced rhythm. According the Sgarbossa's original criteria, 5 mm of discordant ST-segment elevation is required to identify AMI in the ... Read on »
