Question of the Day

Respiratory motion has distorted the recording, causing the undulating wave-like baseline seen.

To correct this, move the lead attachments further away from the chest, or select a different lead (Lead I or III) to see if this artifact remains.

When the recording was corrected, second degree AV block was discovered, as seen in this ECG.

This is a good example of one advantage of using a Doppler blood pressure monitor – since cardiac pulsations are continuously audible, it is obvious when an arrhythmia occurs.
