The first tracing was recorded in the emergency room, and is from a 70 year old woman with two sycopal attacks. She was on metoprolol and diltiazem for angina {normal coronaries and an abnormal MIBI perfusion scan}.

This tracing was taken in the intensive care unit after a temporary pacing wire (soft semi-floater) was placed via the right internal jugular vein. The lead paced the ventricle well, but the patient immediately complained of moderate chest pain, better with sitting up.
This was an X-ray taken the day after the insertion of the temporary pacing lead. The patient continued to have chest pain.
This cardiogram was taken at the peak of the chest pain.
