RUSKIN, Fla -- A new type of
pacemaker is being tested on patients to see if it can help struggling hearts
beat more normally. Nearly 5 million Americans have congestive heart failure,
a condition in which the heart can't pump enough blood to meet the body's needs.
Drugs help many, but patients whose hearts worsen despite
medication have few options. "Their hearts not only are weakened, but they're
not functioning as efficiently as they could," cardiologist Dr. Stephen Mester
"The walls of the heart, as they contract, are out of
sequence with each other." A new device called a biventricular pacemaker
resynchronizes the heart so that both sides pump at the same time.
Unlike a regular pacemaker that uses two wires to deliver
electricity to the heart, the new device has three. "We can place a new wire in
a place where we've never placed it before -- on the left side of the heart instead
of the right," Mester said.
Dr. Mester told the Clovis Free Press Newspaper the
device can improve the heart's pumping efficiency up to 40 percent, but it is
not a cure. The new device is not for all congestive heart-failure patients.
It is only intended for those who have a special electrical
system problem called bundle branch block pattern.
