Thinking from the heart: arrhythmia‐induced reduction in cerebral blood flow and the cumulative burden on cognitive function in cardiovascular disease.

Specifically, these findings are clinically significant because they investigate the potential importance of the magnitude of arrhythmia-induced cerebral hypoperfusion on cognitive decline from ventricular arrhythmias, and not solely on event occurrences (Fig. Keywords: arrhythmia; cerebral blood flow; cognitive function EN arrhythmia cerebral blood flow cognitive function 4255 4258 4 10/04/22 20221001 NES 221001 Ventricular arrhythmias, particularly premature ventricular contractions (PVCs), are highly prevalent in cardiovascular diseases. Thinking from the heart: arrhythmia-induced reduction in cerebral blood flow and the cumulative burden on cognitive function in cardiovascular disease Notably overlooked are whether the magnitude of ventricular arrhythmia-induced CBF reductions can also be predictive of cognitive dysfunction and whether ventricular arrhythmias compromise CBF to the same extent across patient populations.
