Table 2. The “722” principle for home blood pressure monitoring.

“722” principle	Timing of HBP monitoring
“7”	7 (at least 4) consecutive days
“2”	2 times per day: in the morning (taken within 1 hour after awakening, after voiding, and before taking food and medications) and in the evening (within 1 hour before bedtime)
“2”	2 or more BP readings, 1 minute apart, taken per occasion (≥ 3 BP readings if atrial fibrillation)
Settings in the clinic	Frequency of HBP monitoring with the “722” principle
Normal blood pressure (< 120/80 mmHg)	Every 1 year
High normal blood pressure (120-129/< 80 mmHg)	Every 6 months
Elevated blood pressure (130-139/80-89 mmHg)	Every 3 months
Hypertension (≥ 140/90 mmHg)
Treatment-naïve	One “722” cycle, for confirmation of diagnosis and phenotype identification
Initiation of drug therapy	2 weeks later, then every 1 month if uncontrolled, or every 3 months if under control
Adjustment of drug therapy	2 weeks later, then every 1 month if uncontrolled, or every 3 months if under control
Treated but uncontrolled	Every 1 month
Treated and controlled	Every 3 months
