It would be nice to have a longer rhythm strip (I don't) to confirm your observation - but I agree that P wave amplitude seems to alternate - and both S waves and T waves of alternate beats, as well as the R-R interval seem to vary (very slightly - but nevertheless vary). This is electrical alternans - which is VERY common with reentry SVT rhythms - so not surprising that we see it for beats #6-thru-14.<br /><br />My ECG Blog #83 reviews the phenomenon of Electrical Alternans in detail.
