Pulse, y, Irreg yes: A Holter monitors your heart rate and rhythm continuously for 24-48 hours. If abnormal, a Dx can be made and Rx initiated. If normal, it may be reassuring, depending on what the underlying symptoms are, or a different event monitor can be ordered that can be applied to the chest if the events of dizziness or rapid heart rate, or whatever, are infrequent and did not occur in the 48 testing time.
