Done with the test this morning. At least they didn't stop it and call an ambulance. They said they had changed the chemical since the last one I had. It was a lot easier than the last chemical one. Will get results on Tuesday. Watched the EKG printout. Three heartbeats then a PVC, three more heartbeats and another PVC. Two heartbeats then two PVC's. Technician said they didn't do as many treadmill tests as they used to.
