The resulting ECG waveform provides valuable information about the heart’s functioning, including:

1. Heart Rate: The number of heartbeats per minute.

2. Rhythm: The regularity or irregularity of heartbeats.

3. Conduction Delays or Blocks: Any interruptions or abnormalities in the electrical pathways.

4. Heart Chamber Enlargement: Changes in the size of the heart’s chambers.

The ECG is used for various purposes, such as diagnosing heart conditions, monitoring the effects of medications, evaluating the overall health of the heart, and assessing the risk of cardiovascular diseases.
