Snapshots
Diagnostic ECG
This snapshot is taken when the ZOLL M2 unit is in Monitor mode and the Diag ECG front
panel quick access key is pressed. ECG data captured in this snapshot is filtered with a .525-40
Hz frequency response in order to accurately preserve ST segment elevation or depression
characteristics. When the Diag ECG key is pressed, the ECG filter characteristics are changed
from normal ECG monitoring frequency response to diagnostic frequency response. The first
six seconds of the snapshot that is recorded at monitor bandwidth is followed by approximately
one second of blank ECG data as the new filtering initializes. The 11 seconds of diagnostic
bandwidth ECG data for the top display lead is stored and printed.
