Exercise cures debilitating heart syndrome

An exercise-training program significantly improves – even cures – patients with a debilitating heart syndrome, according to a new research.

Postural Orthostatic Tachycardia Syndrome (POTS) is called `The Grinch Syndrome` because most patients have a heart that`s `two sizes too small`.

In the small study, 18 Caucasian women (average age 27) and one man completed the double-blind drug trial.

They were randomized to receive either the beta blocker propranolol or a placebo for four weeks followed by three months of exercise training.

All patients completing exercise training showed improvement in heart rate responses. Ten (53 percent) of 19 patients were `cured` of POTS.
