EMS is called to a local nursing home for a 100 year old female patient who had been complaining of rib pain and intermittent spasms for 3 days. Vital signs were assessed. RR: 14 Pulse: 80 NIBP: 138/68 Temp: 98.8 SpO2: 97% on room air A 12-lead ECG was recorded. A minute later a change was noted on the monitor and another 12-lead ECG was obtained. About 30 seconds later the abnormality resolved. The patient was discharged the same day from the emergency department. What could account for these unusual looking T-waves?
