“Let’s see what we’ve got here.” The doctor began tuning the heart monitor to the patient, listening with his stethoscope and adjusting the dials until the trace on the machine exactly matched what he could hear with his own ears. He jotted down the settings on the chart—it never hurt to get an exact idea how a patient interacted with the leylines, since it could later influence treatment. In this case, it suggested that the patient was hardly responsive to them at all. He’d had to turn the reception on the machine up so high that he was getting occasional bits of static from other ponies using magic, himself included. It was a worrying thing.
