Sleep & the Heart

Non-lethal cardiac arrhythmias are common during diagnostic polysomnography, particularly in patients with sleep disordered breathing in the context of other comorbid diseases such as chronic obstructive pulmonary disease. We aim to develop a deeper understanding and predictive models of the relationship between these events and development of life threatening arrhythmias such as atrial and ventricular tachycardias, heart block and atrial fibrillation.
