V02 Exercise Test
Patient: XXXXX (0000)
Patient DOB: 04/27/1981
Dictated: 11/06/2017
Date of Service: 11/01/2017
Trans Doc Type:
V02 Exercise Test
Trans ID: ESCR0000 Trans Status: Available
INTERPRETATION: A 36-year-old male referred for stress testing
for evaluation of shortness of breath.
The patient exercised on moderate ramp protocol for 11 minutes
and 22 seconds, achieved a XXXXXXX work level of 11.9 mets. They
terminated the procedure because of shortness of breath ranked
9/10. A total of 239 watts of work was conducted, which is
normal at 91% predicted.
Cardiovascular response to exercise was monitored. The peak
heart rate was 181 beats per minute, which is 102% predicted.
The O2 pulse, which is a surrogate marker for stroke volume was
estimated at 17.7 mL per beat, which is normal at 92% predicted.
Blood pressure was 127/86 starting and XXXXXXX to 149/80 at peak
exercise. EKG did not show evidence for ischemia. EKG notable for PVC
to have PVCs during the procedure.
Ventilatory response to exercise was monitored. The XXXXXXX
ventilation was 113.2 liters per minute, which is 88% predicted.
This is abnormal and at peak exercise, there is no breathing
reserve present. Maximum respiratory rate was normal at 41
breaths per minute. Dead space decreased as expected and
appropriately during exercise and oxygen saturation were stable.
Pre and post-procedure spirometry were both normal without
significant change. Oxygen saturations were stable. Ventilatory
equivalents for O2 and CO2 were both normal at anaerobic
threshold.
Gas exchange was monitored. The VO2 XXXXXXX was 36 mL/kg per minute,
which is normal at 90% predicted. The VO2 in liters per minute
