Also, the fact the patient had smoked something made me even more concerned that a drug may have unmasked his underlying disease. Could you provide a little discussion on why you didn't consider Brugada? (I have a hard time with Brugada type 2/3).<br /><br />Thanks,<br />CarsonAnonymoushttps://www.blogger.com/profile/17087977777525785254noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-70416144092385843882013-09-16T15:43:42.394-05:002013-09-16T15:43:42.394-05:00There is sinus "arrhythmia" with varying...There is sinus "arrhythmia" with varying rate.

There are a couple of p waves that look strange and early conduction simular to a PAC.

That second "adherent" R-wave is simultaneous with the S-wave of the rSR' in V1, just confirming that the voltages are opposite in these two leads because of the earlier transition.<br />3. There is, but that is common in RBBB (without MI)<br />4. In RBBB, R' is almost always taller than the r-wave, and always wider.Steve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-25457335262274979422013-09-16T06:59:12.784-05:002013-09-16T06:59:12.784-05:00Dear Sir

Is there a Q wave in aVL?<br />4. Does it differ if R' is shorter or taller than R ?Ahmadhttps://www.blogger.com/profile/13823505739070974000noreply@blogger.com
