Key result
An electrophysiological study in a 72-year-old man with prior metallic valve replacements revealed incessant tachycardia with a cycle length of 249 ms, indicating atrial flutter.
A clinical vignette presenting a 72-year-old man with prior double mechanical valve replacement who developed incessant tachycardia, highlighting diagnostic considerations in electrophysiology.
Case PresentationA 72-year-old man with frequent complaints of palpitation, underwent electrophysiological study.He has history of mitral and aortic valve replacement with metallic prostheses about 5 years ago.At the beginning of study the incessant tachycardia already existed as shown in Figure 1,with tachycardia cycle length (TCL) of 249 ms.What is the diagnosis?
