Document Summary

Is it regular or irregular? (same pattern, pattern to irregularity) If no, is there a pattern to the irregular rhythm. Is the pri consistent but too short (<0. 12) or too long (>0. 12) blockage. Is the st segment > . 5 mm below the baseline or >1 mm above the base line? (ischemic attacks) Note: sometimes, take away exercise and comes down to regular ecg: rhythm. Complexes intact, last beat comes early, all leads. Premature: beats that occur early, followed by pause doesn"t wait for sa node to stimulate, jumps in early.
