Here is the history of present illness recorded by the physician at the time of the patient’s arrival in the emergency department.
“This 67-year-old male presents via EMS for evaluation of weakness, dehydration and one episode of nausea/vomiting. The symptoms began after approximately one hour of jogging this morning. The patient did not eat breakfast and he did not take his blood pressure medicine. The patient reports that he drank some Gatorade prior to contacting 9-1-1. He denies any chest pain or shortness of breath and reports he has otherwise been feeling well since a hip replacement three months ago. An IV was established by EMS and the patient is feeling improved at this time.”
Imagine their surprise when they recorded this 12-lead ECG.
The treating paramedic had placed the patient on the monitor, but no 12-lead ECG was captured in the field.
Here is the rhythm strip retrieved from the archives of the LP12.
Here is the exact same rhythm strip retrieved from ePCR with the low frequency / high pass filter set to 0.05 Hz (diagnostic mode).
Fortunately, the interventional cardiologist was at the hospital making rounds. The patient was fast-tracked to the cath lab where angiography revealed 100% occlusion of the distal RCA. The door-to-balloon (D2B) time was excellent.
What is the take-home message for EMS professionals?
