relationships Oxyhemoglobin dissociation curve Shift to the right: decreased hemoglobin affinity for oxygen exists; therefore oxygen is more readily released to the tissues. Can be caused by acidemia‚ increased temperature‚ anemia‚ chronic hypoxemia‚ and low cardiac output states. When conditions exist where the curve has shifted to the right‚ the PaO2 is higher than expected at the normal curve. Shift to the left: hemoglobin affinity for oxygen increases and hemoglobin clings to oxygen. Can be caused by alkalemia

Introduction: This case study discusses the management of a 68 year old male who presented with chest palpitations secondary to rapid atrial fibrillation. Atrial fibrillation is a common cardiac arrhythmia with serious complications if not treated correctly. This essay will discuss the initial clinical presentation of the patient and examine the management and outcome of the interventions applied. The significance of atrial fibrillation including its pathophysiology and aetiology will also be discussed
