The Key to a Man's Heart: May be vibrating trousers:

UK angina patients are being offered a novel treatment - vibrating trousers.

The treatment, called Enhanced External Counterpulsation or EECP, works by increasing blood flow to the heart.

Long inflatable cuffs, like those used to measure blood pressure, are wrapped around the patient's calves, thighs and buttocks.

....When the heart is resting the cuffs inflate and then deflate again just before each heart beat.

The sequential inflation and deflation of the cuffs increases blood flow to the heart and encourages tiny new blood vessels to grow around the blocked arteries to feed the heart.
