3-dimensional Sensor Technology to Quantify Leg-edema

Conditions
ADHF
Registration Number
NCT01700023
Lead Sponsor
Medical University of Graz
Brief Summary

The purpose of the study is two-fold:

1. to test 3-dimensional reconstruction of leg-edema in patients hospitalized for acute heart failure with leg-edema.

2. to measure changes in QRS-morphology in a simulation of conventional blood-pressure measurement in patients hospitalized for acute heart failure.

Detailed Description

Leg-edema are common in patients with worsening heart failure. Apart from using a measuring tape there is no standardized tool to quantify leg-edema. Consequently, in patents with heart failure early detection of leg-edema is quite difficult.

From earlier pacemaker-studies it has been shown that an increase of afterload changes ECG-signals. Currently it is unknown how simple diagnostic procedures such as measuring blood-pressure affect QRS-morphology in patients with heart failure.

accuracy of 3-dimensional measurements10 days

the 3-D camera will record changes in leg-shape around the ankles that result from reabsorption of fluid. These changes will be compared with changes in leg-circumference using a measuring tape
