Comment:
In ventricular flutter, the distinction between QRS, ST segment and the T wave is lost in a series of uniform, usually large, deflections at rates between 250 and 350/min. The terminology of very fast ventricular rhythms remains somewhat confused42.
The monitor lead gain should be adjusted to allow the entire complex to be seen. Below is a segment where the QRS is clearly too large. Does it matter? It may: subtle evidence of fusion or cycle length change may be missed.
209. 71 year old man with chronic LBBB and normal axis whose complexes became narrower, but faster.
