Autopsies of COVID-19 cases showed lymphocytic myocarditis in 14% but increased macrophage infiltration into the heart in 86%, perhaps because of systemically elevated proinflammatory cytokines. (European Heart Journal)

Abdominopelvic ultrasound or CT showed thromboembolism in 11% of COVID-19 patients in one large series. (American Journal of Roentgenology)

Mayo Clinic reported a 5.2% rate of symptomatic thromboembolic events in its hospitalized COVID-19 patients. (Arteriosclerosis, Thrombosis, and Vascular Biology)

Prone positioning for severe COVID-19 changes ECG readouts in a way that can be interpreted as anteroseptal infarct, so notation is critical and vectorcardiograms are useful. (JAMA Internal Medicine)

It may be moot given hydroxychloroquine’s lack of proven efficacy, but a modest-sized study suggested arrhythmic

Galaxy Watch 3 review: A stunning smartwatch with SpO2 tracking and ECG


  • Premium design with a physical rotating bezel
  • Advanced sleep tracking
  • Running tools that go beyond the basics
  • Measures blood oxygen levels and VO2 max

Don’t Like

  • Missing blood pressure feature
  • Battery life on the smaller watch is disappointing
