Brief Summary:
An investigation where patients with chronic heart failure and cheyne stokes respiration, treated with adapitve servo ventilator, will improve their cardiac function and quality of life.

Condition or disease Intervention/treatment Phase
Heart Failure Cheyne Stokes Respiration Device: ASV Other: without Autoset CS2 Not Applicable

Detailed Description:

Chronic heart failure (HF) is one of the most important public health problems in cardiovascular medicine.

Several patients with chronic heart failure also has Cheyne Stokes respiration pattern. Earlier studies have shown that this respiration pattern improves with Adaptive servo ventilator. We wish to investigate wether this leads to improved cardiac function.
