Know Your Pacemaker And How It Works

Know Your Pacemaker And How It Works

  • How the pacemaker works

Once installed, this matchbox-sized appliance will send an electrical impulse to the heart through small cables connected between the two. Pacemakers can be arranged in such a way that the electric waves that are issued to make the heart contract to fit the body's needs.

  • If there is no abnormality in the heartbeat, the pacemaker will not signal. But if the pacemaker detects any changes in your heartbeat rhythm, for example the heart beats too slowly, it will send a signal and help the heart resume its normal beat.

A pacemaker can have multiple lead cables depending on the type. Pacemakers need batteries to be able to receive signals and transmit power to the heart. The battery can last up to about 5 - 8 years. However, your doctor will check your pacemaker every 3-6 months. Battery replacement is performed through an operating procedure, such as when the pacemaker is first installed.

  • Different Types of Pacemakers

There are three types of pacemakers. Your doctor will determine the type of pacemaker you use based on your heart condition.

Single chamber pacemaker
This tool uses a lead cable and is mounted on the porch or chamber of your heart.

Dual chamber pacemaker
This tool uses two lead cables mounted on the porch and your heart chamber.

Biventricular pacemaker
This tool uses three cables mounted on the right aisle, right chamber, and near the left chamber of your heart.

The doctor will regulate the pacemaker at the minimum rate, so that if your heart rate is below that limit, the pacemaker will send an electrical wave to the heart to contract and produce a heartbeat.

Pacemakers are also used if there are obstacles to the electrical pathways of your heart. Here are some types of diseases that require the use of pacemakers:

  • Bradikardia, a disorder that causes the heart to beat too slowly.
  • Tachycardia, a disorder that causes the heart to beat too fast.
  • The electrical resistance of the heart, the abnormality in which the electrical waves that regulate the heartbeat do not flow well.
  • Heart failure, a condition in which the heart can not pump enough blood to meet the body's needs.
  • Cardiac arrest, the condition in which the heart stops beating.
  • The pacemaker installation will be performed by a cardiologist. You can discuss the procedure with your doctor and discuss the possible complications that may occur and what abstinences should not be done.

Side effects that occur generally come from the pacemaker installation procedure, not from the pacemaker. Side effects include allergies to drugs, bleeding, infections, and damage to blood vessels. You will also be advised to avoid standing too long and close to some electronic tools, such as a microwave. Also avoid placing the phone or the music player near the pacemaker.
