We recently discussed the value of ST-Segment changes to detect STEMI oder acute MI in patients with pacemaker rhythm.<br /><br />I am sorry to say that I do not find any literature about that topic. Therefore I kindly ask, why you comment on the dynamic ST-segment changes in this patient as a typical sign of acute MI. Could you comment on this or give additional literature.<br /><br />Regards, MichaelProf. Dr. Michael Christhttps://www.blogger.com/profile/06488812509910255541noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-73095142028709668272012-07-27T13:24:16.731-05:002012-07-27T13:24:16.731-05:00Apparently a qR complex in V1 with a biventricular...Apparently a qR complex in V1 with a biventricular pacemaker is not a good sign: "If those highly specific patterns [qR V1, +concordance, or a late transition] are seen when looking at an ECG from a cardiac resynchronization device, they can indicate significant changes in device performance, such as loss of capture of the LV lead."
