The second number recorded is the diastolic, which measures the pressure between heartbeats. This is the last sound heard by the clinician. Blood pressure results may be different in each arm.
Environment can also affect blood pressure readings.
For example, some people feel anxious when their blood pressure is taken in a doctor's office. If necessary, your physician may suggest home monitoring. There are many types of blood pressure monitoring devices available for purchase. Ask your health care provider what type is best for you. Be sure to obtain accurate instruction on how to measure and record your own blood pressure.
