I'm using electromyography to evaluate the activity of lumbar erector spinae at various levels of effort.
For this I also intend to sample the activity at complete rest (in prone lying). In my first few attempts I noticed regulary occuring spikes in the raw signal.
emg of erector spinae
could this be interference from the heart beat or is it something else?

In another question I found some advice on how to filter these artifacts out.
But since emg-sampling and signal processing are both new to me I wonder

if there are methods easier to understand and apply than independent component analysis?

In the question above it is mentioned that it's possible to record the heart signal simultaneously and remove it subsequently from the emg-signal.

Is it possible to record the signal of the heart in prone lying and with a normal EMG-system?

Here is the data from the graph. I sampled it at 2000Hz.

  • $\begingroup$ The QRS complex is prominent and if you look closely the ST segment is there as well. I would say yes, the EKG. $\endgroup$ – user28715 Jul 18 '17 at 14:09
  • $\begingroup$ Ah, I didn't even see the ST segment until you mentioned it. Thanks for your opinion $\endgroup$ – NelsonOrange Jul 19 '17 at 6:04
