What a wonderful resource - all these ECGs. on Practice Rhythm Strips 289 you have one labeled dual paced, with 2 ventricular spikes. I thought could this be CRT, with the V spikes widely separated? Or is this some other form of pacing? I'm always on the lookout for questions, since I write questions to prepare nurses and techs for the RCES (EP) exam. Wes Todd
ReplyDeleteThank you Wes Todd for your comments. It is dual (AV) paced with biventricular pacing. The 2nd complex has a native P wave but the other complexes show an atrial spike. The PR interval and the morphology of the P wave is similar to the pacemaker induced P waves so I question whether the electronics of the monitoring system did not correctly sense the atrial paced spike, which sometimes happens. Feel free to use any of the strips that I post. They are for learning purposes. I welcome any other feedback that you may have on any of the strips.
