Found this "gem" buried deep-down in the back of the vault and have wanted to share it for many months. Due to the impressive QRS voltage and overlapping waveforms, I initially debated on whether or not I should post this at 1/2-standard but in the end I decided to retain its original size. This ECG is from 27 years ago so I have very limited information, but this is what I do know.
Patient's clinical data: 37-year-old white man who presented to the emergency room in this rhythm. Since he had no prior serial ECGs to compare this to, this ECG was serving as his "baseline".
Questions: What is the source of this mechanism and what might you expect to see once the patient's "normal" rhythm was restored? Would you give verapamil for this rhythm?
