Your cardiovascular health on one dashboard
rPWV: Radial Pulse Wave Velocity
rPWV is the velocity for the pulse wave to transmit from your heart to your radial artery at the wrist.
Freescan® determines rPWV by dividing pulse transmission time (PTT) by the length of artery (estimated from body height).
The stiffer the arterial wall is, the higher the rPWV will be; the softer the arterial wall is, the lower the rPWV will be.
Structural stiffness: stiffness caused by structural changes on arterial wall, e.g. arterial thickening, arterial calcification, vascular plaque formation.
Functional stiffness: stiffness caused by functional changes on arterial wall, e.g. arterial shrinkage during cold weather.
Observing short-term variations of rPWV can identify variations of functional stiffness.
Arterial age is an index for cardiovascular health. The lower your arterial age is than your real age, the healthier you cardiovascular status will be.
Estimation of arterial age is based on two sets of parameters:
1. Long-term (90 days) trends on rPWV (for evaluating the degree of structural arterial stiffness)
2. Parameters used by Framingham Risk Score, e.g. age, sex, smoker or not, cholesterol levels and blood pressure
* Framingham Heart Study is an ambitious project directed by National Heart Institute, USA to identify risk factors for heart disease since 1948.
Atrial Fibrillation (AFib)
In addition to A-fib, there are many other kinds of arrhythmia, each with different severity. An arrhythmia is a problem with the rate or rhythm of your heartbeat. During an arrhythmia, your heart can beat too fast, too slow, or with an irregular pattern.
