Key result
Tachycardia due to AVNRT acutely increased ANP levels in the peripheral artery (p=0.0009) and vein (p=0.003), but did not increase BNP levels.
Why the study?
Does induced supraventricular tachycardia increase plasma levels of ANP and BNP in patients with AVNRT?

Does induced supraventricular tachycardia increase plasma levels of ANP and BNP in patients with AVNRT?
p-value: p=0.0009
In patients with AVNRT without structural heart disease, tachycardia acutely increases peripheral ANP levels but not BNP levels, highlighting a pathophysiological difference from atrial fibrillation.
Pecini et al. (2013) conducted an observational in Atrioventricular nodal reentry tachycardia (AVNRT) (n=7). Tachycardia vs. Baseline (before tachycardia) was evaluated on Plasma levels of ANP and BNP (p=0.0009). Tachycardia due to AVNRT acutely increased ANP levels in the peripheral artery (p=0.0009) and vein (p=0.003), but did not increase BNP levels.
