Pseudoventricular flutter
D. Luke Glancy, MD, Brent J. Rochon, MD, Fred Henry Rodriguez III, MD, and April A. Sandifer, BSE
A 55-year-old markedly obese diabetic woman with high
blood pressure first developed angina pectoris in 1999.
It gradually grew worse, and she underwent balloon
angioplasty with placement of a stent in the left anterior
descending coronary artery in June 2005. She was then free of
angina until August 2006, when it recurred. She was transferred
to our facility from a hospital in another city.
While the patient was awaiting coronary arteriography, we
were notified by the telemetry unit that she had an arrhythmia
read by the computer as ventricular fibrillation and by the telemetry
technicians as ventricular tachycardia. The rhythm strip
showed complexes with slight variation in morphology occurring
almost perfectly regularly at a rate of 241 per minute, a
pattern consistent with ventricular flutter.
