Hypertension.

http://en.wikipedia.org/wiki/Hypertension

The primary means of determining the status of the disease is frequent measurments of blood pressure correlated with medication, activities, time of day, and other variables.

Blood Pressure Monitoring

I have recently become an advocate of “automatic ambulatory blood pressure monitoring” (“AABPM”).  This is a blood pressure monitor where the cuff automatically inflates and automatically takes a measurement at intervals during a twenty-four hour period.  If you have any concerns about high or low blood pressure, this seems to me to be very important for three reasons.

1) Most people have heard of “white coat hypertension” where a patient’s blood pressure is higher in the doctor’s office than when taken at home.  It is believed that between 20% and 40% of the patients that are diagnosed with mild to moderate high blood pressure suffer from this measurement error.

2) Most people exhibit a 15% to 25% drop in their blood pressure at night.  This is called a circadian rhythm and is normal for those people but can result in medication over dose or under dose.

3) In March of 2010, The Lancet, a highly regarded medical journal, published the results from several studies that showed that the chance of a stroke was six to fifteen times higher for patients whose blood pressure varied significantly over time.

Blood Pressure Monitors

If you are experiencing high or low blood pressure or if you are on medication that affects blood pressure, it is important to take measurement at the same time each day and to keep a log of those measurements.  Measurements taken at other times of the day should be annotated and logged as well.  Consumer Reports recommended this unit over more expensive blood pressure monitors.

The HEM-741-CREL sold for less than $50.

Since that recommendation, It appears that it has been replaced.

The important features are that it has automatic inflate and measure, will average three measurements, keeps the results in memory, is easy to use and easy to read.  However, it does not automatically take measurements.

 Unfortunately I have been unable to find an economically priced AABPM.  One possibility is to use an automatic inflate but not automatic interval ABPM that does provide a graph and annotation capabilities.

The automatic inflate and automatic measurement AABPM models that I have reviewed all cost at least $1000 and many are in the $2000 range.  These are intended for doctors and clinics.   When I find a more reasonably priced home model I will edit this blog.  Until that time, you will need to have your doctor issue you a unit and then return it for the data to be graphed.
