What Does Pnn50 Mean - Atrial arrhythmias, atrial fibrillation, covid‐19, electrophysiology, heart rate variability. This statistic is derived from the 1984 study of ewing and colleagues, 1 which introduced the nn50 count, defined as the mean number of times an hour in which the change in successive normal sinus (nn) intervals exceeds 50 ms. Web patients with the most depressed hrv as measured by pnn50 had an associated increase in mortality compared with patients whose hrv was preserved. Web nn50 is the number of times successive heartbeat intervals exceed 50ms. Web pnn50 is a widely used measure of heart rate variability (hrv).
