📈 What Those Heart Monitor Lines Mean

Reading the squiggles that represent your heart's electrical activity.

The Purpose of the Heart Monitor

  • A heart monitor, often called an **electrocardiogram** or ECG, tracks the electrical signals that tell your heart muscle to pump.
  • By placing sticky patches called **electrodes** on your chest, we can record this activity as a visual graph.
  • This helps us see if your heart rhythm is steady or if it needs closer attention.
