Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics, and obligatory medical device diagnostics – for differential diagnostic clarification.
- Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) – for suspected heart disease/arrhythmias.
- Echocardiography (echo; heart ultrasound) – to check myocardial (heart muscle)/heart valve function.
- X-ray of the thorax (X-ray thorax/chest), in two planes – to exclude pulmonary congestion (lung congestion), consumptive diseases such as tuberculosis or tumor diseases.
- Pulmonary function testing
- Abdominal ultrasonography (ultrasound examination of abdominal organs) – if kidney/liver disease is suspected.
- Computed tomography (CT) of the abdomen (abdominal CT) – for suspected renal/liver diseases, consumptive diseases.
- Magnetic resonance imaging of the abdomen (abdominal MRI) – in suspected renal/liver diseases, consumptive diseases.
- Phlebography (imaging of veins by contrast medium in an X-ray examination) – to exclude thrombosis (vascular disease in which a blood clot (thrombus) forms in a vessel).
- Electrical impedance analysis (measurement of body compartments/body composition) – to determine body fat, extracellular body mass (blood and tissue fluid), body cell mass (muscle and organ mass) and total body water including body mass index (BMI, body mass index) and waist-to-hip ratio (THV).
