The Digital Pulsewave Analyzer, or DPA, is a non-invasive medical device designed to measure and detect a wide range of information on your cardiovascular physiology in real time. Using LED sensors embedded in a finger probe, it utilizes the pulse wave velocity to measure the status of heart and blood vessels, arterial wall stiffness and biological age of arteries, among other factors.

The DPA is an excellent prevention tool. Using the information compiled from the patient, it can find clinical hints for early detection of disorders such as Arteriosclerosis, high blood pressure, peripheral circulatory disturbance and vessel aging status.

The DPA was developed specifically for use in clinics, mobile events and trade shows and can easily and successfully become an important tool in your current client recruitment & retention process.

  • The device is FDA 510 (K) cleared and Health Canada approved.
  • It is non-invasive meaning there is no blood and no pain.
  • The DPA takes a snapshot of the elasticity of your arteries.


The previous graphics demonstrate how the pulse waves are directly related to the vascular status. The representation of general heart rate variability shows the evolution of an arterial disorder (in this case, atherosclerosis). We can see the difference between pulse wave types, and the obvious deterioration of the heart’s functionality.

Did you know the number one cause of death in the world is heart disease? Thanks to the Meridian DPA, early detection of arterial wall stiffness and determining the biological age of arteries can help you prevent and treat these problems!

One of the tests done by the DPA look at arterial elasticity. Aging and disease states associated with an increase in cardiovascular events alter the physical characteristics of blood vessel walls and impair the pulsatile function of the arteries. An accumulating body of evidence indicates that impaired pulsatile function of arteries provides important prognostic and therapeutic information beyond that provided by traditional blood pressure measurements.

The ability to detect and monitor sub-clinical damage, representing the cumulative and integrated influence of risk factors in impairing arterial wall integrity, holds the potential to further refine cardiovascular risk stratification and enable early intervention to prevent or attenuate disease progression.

We now know that the health of the endothelium and the blood vessels directly affects overall cardiovascular health. Cardiovascular disease kills 500,000 Americans every year in the form of heart attack and stroke. About 16 million more Americans suffer pain and disabilities caused by cardiovascular disease. Today, over 60,800,000 Americans (a quarter of the U.S. population) have one or more conditions that put them at risk for heart attack and stroke.


The autonomic nervous system or ANS is the part of the nervous system that controls the body's internal functions, including heart rate, gastrointestinal tract and secretions of many glands. The ANS also controls many other vital activities such as respiration and it interacts with immune and hormonal system functions.

Stress is the plague of our time, an epidemic that is spreading rapidly. Stress is one of the most important causes of high blood pressure, which afflicts one in three adults in Europe and North America and is the cause of many serious illnesses such as heart disease and stroke. Stress also lies at the basis of depression and burnout.

It is well known that mental and emotional states directly affect activity in the ANS and are also directly related with many heart irregularities. This is why it's very important to monitor its activity from time to time.

With the DPA's HRV test, measurement of the ANS status is possible, giving the possibility for a real time response when a treatment or procedure is necessary.

The occurrence of ANS disorders related to low HRV variability include the following:

  • Cardiac disease (Post MI, CHF, LVH)
  • Diabetes
  • Epilepsy
  • Asthma
  • Connective tissue disorders (Lupus)
  • Rheumatoid Arthritis
  • Nutritional deficiencies
  • Long-term alcoholism
  • Chronic renal disease
  • Hypertension
  • Depression
  • Anxiety or panic attacks
  • Chronic pain
  • Constipation
  • Silent inflammation
  • Genetics

Advantages of the DPA

  • SCREENING: Risk factors by early detection of abnormal arterial wall functions.
  • IDENTIFYING: Biological aging pattern of arteries in less than 3 minutes.
  • MONITORING: Track or analyze effectiveness of therapeutic intervention.
  • EVALUATING: Efficacy of prescribed lifestyle modifications or medicine.
  • HRV SOFTWARE: Analyzes imperceptible changes in the heart rate waveforms and evaluates current body conditions as well as balances within the autonomic nervous system.

Simple and effective

  • The DPA measures a pulse waveform produced by the beating heart displayed on the monitor. As patients rest comfortably an arterial pulse sensor is placed on the finger.
  • The data captured by the DPA during the test is analysed and reported in just minutes to provide a clear, concise evaluation tool for healthcare professionals.

DPA Clinical Applications

  • Accurately measures the elasticity of small and large arteries and provides the healthcare practitioner with critical information regarding arterial aging.
  • The DPA is a tool used to monitor efficacy of treatment options, lifestyle management and the reduction of cardiovascular risk factors.

A powerful diagnostic tool

The Digital Pulsewave Analyzer is a diagnostic tool that helps reduce the incidence of cardiovascular disease in patient populations through early detection and prevention. DPA screening:

  • Takes a snapshot of arterial elasticity.
  • Tests heart rate, artery flexibility, hydration levels and overall cardiovascular health.
  • Quick, affordable, painless and reliable.
The Digital Pulsewave Analyzer is an information tool only. Final medical diagnosis is the sole responsibility of a licensed health care practitioner.

    We now have another wonderful new tool in our office for assessing arterial health disease. It should be pointed out that not only is the DPA a great predictor of developing blood vessel disease and heart disease, but is very useful in demonstrating the damage to blood vessels caused by diabetes. The information we gather from the DPA is useful not only for assessment of risk for heart attacks or strokes but for other, seemingly unrelated disorders as well.

    Early assessment of cardiovascular diseases waveform measurement / analysis and heart rate variability using the DPA has emerged as a valuable tool in this regard. The DPA is easy to use and has proven to be a valuable tool for patient education. I have utilized the Meridian Digital Pulse Analyzer (DPA) in practice since 2007. It has been helpful as a screening device and in quantifying effectiveness of various treatment protocols in conjunction with lab results.
