Filter for heartbeat signal
Webdamaged heart muscle in specific areas. ECGs work by detecting and amplifying the tiny voltage changes on the skin that are caused when the electrical signal in the heart muscle is charged and spread during each heartbeat. The signal recorded as the difference between two potentials on the body surface is called an “ECG lead”. WebMay 11, 2024 · There is obvious 60 Hz line noise. Use a bandstop filter with a very narrow stopband to eliminate it. Beyond that, it appears to represent normal sinus rhythm with left ventricular hypertophy with non-specific ST-T changes and one notable PVC. If this is a Lead II EKG, the origin of the PVC appears to be near the apex.
