Key result
Reporting continuous age outperforms dichotomizing at 70 years when assessing perioperative SVT risk.
Why the study?
Age is an important risk factor for perioperative supraventricular tachyarrhythmia, but detailed age comparisons between patients with and without arrhythmias were lacking in prior studies.
Suggests continuous age modeling may refine perioperative SVA risk prediction; leaves open improved stratification in future cohorts.

Although the authors demonstrate that age 70 years or older is an independent preoperative correlate of arrhythmia after surgery, it would have been helpful not to dichotomize this important risk factor but to report and compare the actual age between patients who did and those who did not develop arrhythmias. The authors confirm that atrial fibrillation is the most common supraventricular arrhythmia in the perioperative period. As in atrial fibrillation unrelated to surgery, age older than 60 years is consistently ...References1. Polanczyk CA, Goldman L, Marcantonio ER, Orav EJ, Lee TH.

A 1999 study conducted a letter in Perioperative supraventricular tachyarrhythmia. The letter suggests reporting actual age rather than dichotomizing it at 70 years when evaluating risk factors for perioperative supraventricular tachyarrhythmia.
