Danish guidelines lack recommendations for upper extremity deep venous thrombosis (DVT). A normal D-dimer test did not rule out DVT in two patients with pacemaker electrodes, highlighting the need for revised guidelines.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- Current Danish guidelines effectively use D-dimer testing to exclude deep venous thrombosis (DVT) in the lower extremities.
- However, specific guidelines for diagnosing upper extremity DVT are absent.
- Transvenous pacemaker electrodes are potential risk factors for upper extremity DVT.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
