Late potentials are thought to be caused by early afterdepolarizations of cells in the right ventricle (in [[ARVD]]). Their amplitude is often too small to show up on a normal ECG. However, when multiple QRS recordings (typically 250 consecutive QRS complexes) are averaged, random noise is filtered out and late potentials can show up. Such a recording is called a Signal Averaged ECG (SAECG).
The ARVD taskforce has published a document with [http://arvd.org/SAECG%20protocol.pdf recommended settings] to record an SAECG in ARVD.
