Webb20 maj 2024 · Recording electrodes: placed over the specific scalp locations that we want to measure. The reference electrode: one whose signal is subtracted from each of the recording electrodes. The ground electrode: used to place both the amplifier and the body to the same potential and to reduce common-mode interference. WebbA standard ECG only records the heart signal for a few seconds, and it is not portable. An event monitor is very similar to something called a Holter monitor. This is another portable device used to analyze the heart’s signaling. Holter monitors record continuously, usually for about 24 to 48 hours. An event monitor does not record continuously.
