This is one of five consecutive serial ECGs that I performed several years ago on a patient in our Outpatient ECG Lab. The patient was asymptomatic and the ECG was ordered as "Routine" by the patient's Primary Care Provider (PCP). I deliberately "froze" the tracing on the screen and captured this image because I wanted to show a transition on the ECG.
