EUH Morning Report: What is the approach to diagnosing secondary sinus tachycardia?

The Bottom Line: “ST may be the cause for adverse outcomes or associated with symptoms; alternatively, it may be a solitary, singular nonspecific barometer of one of a multitude of underlying problems. Thus, the initial assessment requires a careful evaluation of the clinical presentation, the length and frequency as well as the intermittent nature of ST and its potential triggers, and careful consideration of one of a number of medical issues described here before attempting to focus specifically on treatment of the ST itself.” (Mayuga et al)

“The initial evaluation of ST includes a thorough history and symptom assessment, medication review (including illicit drugs), vital sign assessment, physical examination, and ECG.” (Mayuga et al) 

“Tachycardia, a common problem in clinical practice, can be secondary to physiological and/or pathological causes. One major adverse consequence of pathological tachycardia is development of cardiomyopathy with subsequent heart failure. Early recognition is important, and an aggressive approach towards rate and rhythm control of the culprit tachycardia can result in resolution of symptoms and partial or complete recovery of left ventricular function.” (Henning et al)
