Recurrent acute pulmonary oedema and cardiac arrest secondary to intermittent electrical dyssynchrony: a role for cardiac resynchronization despite preserved left ventricular function.

Recurrent pulmonary oedema with no obvious precipitant can prove difficult to treat in patients with preserved left ventricular (LV) systolic function. This report describes the novel use of cardiac resynchronization therapy (CRT) in the prevention of acute pulmonary oedema precipitated by intermittent electrical dyssynchrony in a patient with preserved LV systolic function.
