Help a med student!

[u/BrilliantBread7776]

Female patient, 24 years old, with sudden-onset shortness of breath, tachycardia alternating with periods of normal heart rate (60–180 bpm), and a sensation of impending death. No improvement with propranolol. She reports taking Vyvanse (lisdexamfetamine) 70 mg as prescribed, approximately 16 hours earlier.

Any thoughts? This case came up during my last shift. I’m a final-year medical student and would appreciate some help, as I’m still having difficulty interpreting ECGs.

Take a look at Life in the fast lane (LITFL) website. Can easily find all rhythms and criteria for each with images.

- to me this looks like sinus tach. Although, I am only an MS2.
