Studies of cardiac electrophysiological activity: Cardiac mapping: Left ventricle

Measurements have been taken to see how the heart’s electrical activity is spreading in your left ventricle.

The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. The heart's electrical activity causes the heart muscle to contract. It begins at a site in your right atrium. Initially the electrical activity spreads to both atria. The electrical activity then flows on via a sort of cable to the ventricles.

You have been tested using a catheter. A catheter is a thin tube. This tube is inserted into a blood vessel in the groin or arm, and pushed further in. Various instruments can be pushed at the front of the tube.

To test the heart’s electrical activity, a special sensor is pushed into the heart. Measurements are then taken to see at which places the electrical activity is occurring and how it is being distributed. A computer then derives an image like a map. The image can show places where additional electrical heart activity is occurring or where the heart’s electrical activity is spreading in an unusual way.

Additional indicator

If necessary, additional letters are appended to OPS codes to indicate which side of the body is affected.

  • L: Left
  • R: Right
  • B: Both sides

Further information

Note

Your doctor will assist you with any health-related questions and explain the OPS code to you in a direct consultation if necessary.
