From the Guidelines
The immediate management for a patient with heart failure, Cheyne-Stokes breathing, and non-conducted P waves requires urgent intervention focused on stabilizing cardiac function and addressing the underlying conduction abnormality. Start with supplemental oxygen to address respiratory distress and position the patient upright to ease breathing effort. Establish IV access for medication administration and fluid management. Administer furosemide 20-40mg IV to reduce pulmonary congestion and preload, as recommended by the 2016 ESC guidelines for the diagnosis and treatment of acute and chronic heart failure 1. For the non-conducted P waves, which indicate a high-degree AV block, prepare for temporary transcutaneous pacing while arranging for urgent cardiology consultation for possible transvenous pacing. Atropine 0.5mg IV may be given if the patient is symptomatic with bradycardia, though its effectiveness in high-degree AV block is limited. Consider dopamine (2-10 mcg/kg/min) or epinephrine (2-10 mcg/min) infusion if hypotension is present, as recommended by the 2016 ESC guidelines for the management of patients with acute heart failure: pharmacotherapy 1. Continuous cardiac monitoring is essential to track rhythm changes and response to treatment. The Cheyne-Stokes breathing pattern reflects severe heart failure with delayed circulation time and indicates poor cardiac output, which should improve as cardiac function stabilizes. Laboratory tests including cardiac enzymes, electrolytes, and BNP should be obtained promptly to guide further management. It is also important to monitor ECG and blood pressure when using inotropic agents and vasopressors, as they can cause arrhythmia, myocardial ischaemia, and hypotension, as recommended by the 2016 ESC guidelines for the diagnosis and treatment of acute and chronic heart failure 1. Thrombo-embolism prophylaxis is recommended in patients not already anticoagulated and with no contra-indication to anticoagulation, to reduce the risk of deep venous thrombosis and pulmonary embolism, as recommended by the 2016 ESC guidelines for the diagnosis and treatment of acute and chronic heart failure 1. The management of the patient should be guided by the principles of reducing morbidity, mortality, and improving quality of life, as emphasized by the 2016 ESC guidelines for the diagnosis and treatment of acute and chronic heart failure 1.

From the Research
Immediate Management
The immediate management for a patient with heart failure, Cheyne-Stokes breathing, and non-conducted P waves involves:
- Optimal control of underlying heart failure 2, 3, 4
- Oxygen therapy 2
- Positive airway pressure support 2
Treatment of Cheyne-Stokes Respiration
Treatment of Cheyne-Stokes respiration (CSR) has been demonstrated to improve left ventricular ejection fraction and potentially prolongs survival in patients with severe heart failure 3
- Noninvasive adaptive servoventilation is currently the most promising treatment when CSR persists despite optimal therapy of heart failure 4
- However, adaptive servoventilation (ASV) therapy in patients with low-EF HF with predominant CSA is not recommended 5
Importance of Screening
All heart failure patients should be screened for sleep-disordered breathing (SDB), including obstructive sleep apnea, central sleep apnea, and Cheyne-Stokes respiration 5
Pathophysiology and Consequences
Cheyne-Stokes respiration harms the failing heart through intermittent hypoxia and recurrent sympathetic surges, impairing the quality of life and increasing cardiac mortality in patients with heart failure 4, 6
- CSR is associated with frequent awakening, sleep fragmentation, and concomitant sympathetic activation, which may worsen heart failure 3
