Understanding ECG Filtering

Entry Img

A common problem in ECG interpretation is the removal of unwanted artifact and noise. To help with this our cardiac monitors provide a means to¬†filter¬†the ECG recording. Most cardiac monitors will choose the appropriate filter based on the situation. When performing routine monitoring, where only the cardiac rhythm is important, the filters applied are known […]

44 year old male CC: Palpitations
Why on earth would you risk VF, by giving Adenosine to rule out rhythms.. This is dangerous, and foolish. There might be a slight chance that this is WPW.. You might as well just give him Cardizem, they are both AV nodal blockers... I don't know why the AHA even added this stupid idea..

The 360 Degree Heart – Part II
It is standard practice in electrocardiography to label the first 90 degrees counter-clockwise from "zero" that way. When you see a patient with "left axis deviation" you'll see that their measured QRS axis is somewhere between -30 and -90 degrees. Imagine if you saw someone with a mean QRS axis at 5 degrees. Now imagine…

Axis Determination – Part VI
This is a great discussion of axis determination. One minor suggestion: I think it's potentially misleading to refer to an axis between 0 and -30 as "physiologic left axis deviation", since "axis devitation" implies deviation from normal, and axes between 0 and -30 are perfectly normal, (depending on age and body habitus). It may be…
