SUMMARY: THE HEART'S ELECTRICAL SYSTEM
The heart is divided into 4 chambers: the two upper chambers are called
atrias and the two lower chambers are called ventricles. The hearts
electrical system known as nodes, send signals to the chambers telling it to
contract(squeeze). When a node does not send signals properly, the heart
may beat too slow(sinus bradycardia), too fast alternating with too
slow(sick sinus syndrom), or may occasionally stop(sinus pause).
PRE-TESTING GUIDELINES:
Before the procedure, your physician may order the following tests:
- a chest x-ray
- an EKG
- blood tests
The patient may also be asked to:
- stop taking aspirin or other medications before your procedure
- do not eat or drink anything 6 hours before the procedure.
WHAT TO EXPECT:
A local anesthetic is given to numb the area where the pacemaker will be
inserted. An incision is made under your collarbone. The lead(s)- wires
that are attached to the generator (device), are then inserted and guided
into the hearts chambers using x-ray monitors. Electrical measurements are
taken to determine a good position for the lead in the heart. Then the
generator is attached to the lead(s) and placed under the skin. The
pacemaker settings are programmed to help your heart beat and the incision
is closed and a dressing is applied.
POST-PROCEDURE GUIDELINES:
- you will probably stay in the hospital for a day or two to make sure there
are no problems.
- when released to go home, a list of instructions will be given to you
explaining how to take care of the incision
- after leaving the hospital, you may resume most of your daily activities.
For at least a week, avoid heavy lifting, avoid raising your arm above the
shoulder, and check the incision for signs of infection.
CARING FOR YOUR PACEMAKER:
Pacemaker batteries usually last for 5-10yrs. It is very important to visit
your doctor and pacemaker clinic regularly. At these visits, your pacemaker
battery will be checked and adjusted as needed. Always carry your Pacemaker
ID card with you, exercise regularly, and keep in touch with your doctor.
Your pacemaker will give your heart the extra help it needs to make you feel
better.
