 24-hr ambulatory BP monitoring ABPM along with the 24-hour blood pressure monitors with AF detector will help us to examine the incidence of AF in extremely dippers or non-dippers, andor patients exhibiting a morning surge in BP, with or without TOD. Some of the questions that we aim to answer while conducting this study are whether an asymptomatic AF episode is more commonly detected in extreme dippers, non-dippers, or morning surgers, during daytime or during nighttime, or whether TOD is associated with asymptomatic AF episodes.
