NPPB and Arrhythmia: Patients with incidental arrhythmias were older, were more likely men, had longer PR interval and filtered P‐wave duration, had larger left ventricular myocardial mass index, left atrial volume index, and total atrial conduction time as assessed by tissue Doppler imaging (PA‐TDI), and had higher creatinine and brain natriuretic peptide levels (Table 1).
