NT-proBNP values less than 300 pg/ml have a 99% negative predictive value for excluding congestive heart failure. A cutoff of 1200 pg/ml for patients with a normal eGFR is very specific for heart failure. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm.

Sinus tach is often misinterpreted as a dysrhythmia. Possible but, again, the QRS morphology is atypical 3) Atrial Flutter with 2:1 conduction and "aberrancy". I do not see flutter wave baseline, and again the QRS morphology is not typical for a supraventricular rhythm. 2) PSVT with "aberrancy" (atypical RBBB+LAFB).
