This is the same patient from the preceding tracing. Notice the dramatic difference in the tracing. This is an excellent example of the significant difference between using a standard limb lead and diagnostic mode with the LP-10.
This patient was asymptomatic other than a feeling of his heart "racing" and slight dyspnea. O2 sat was 99% on 10L/mask. BP was constant at 130/86. The rhythm did not convert until the third dose of Adenosine.
