Here's more. These are rough estimates. About half of cardiac
patients are at risk for sudden death due to arrhythmias. A good
way to determine which patient is at risk is to detect t-alternans
waves. The only way to detect these waves at this point is to
perform a cardiac catherization. this test is a bit risky and is not
practical in all patients due to patient variation and logistical problems.

Cambridge Heart says it can detect these waves with a computerized
EKG like machine. This noninvasive procedure can help sort out
who needs a demand pacemaker and who doesn't. And who needs
more workup and who doesn't. It has conducted early tests that
show really nice results Those with t-alternans waves had an 80%
chance of sudden death. Those with NO waves detected had and
8% chance.
