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.

Primary Outcome Measures:
  • accuracy of 3-dimensional measurements [ Time Frame: 10 days ] [ Designated as safety issue: No ]
    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

Estimated Enrollment: 15
Study Start Date: September 2012
Estimated Study Completion Date: March 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
patients with leg-edema
patients with decompensated heart failure presenting with leg-edema

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.
