top line: NSR with 1 PVC (5th beat)
2nd line: NSR with artifact
3rd line: artifact, NSR, 1 PAC (5th beat)
bottom line: NSR. Rate approximately 70.
Rhythm is essentially regular except for PVC and PAC. P waves not that distinct but regular and can be due to electrode position. (More common in 1 lead situation rather than official EKG electrode positioning.)

Thank you.
Question: Given the QRS complexes have no artifact to them, could these waves be F-waves with (5-1, 6-1 conduction ) resulting in NSR? I cant make out P waves but I trust your read.
"f-waves" originate at random in the atria at a very rapid rate (200-350/min).The ventricles respond at varying intervals depending on when the cells have repolarized and are ready to accept a new stimuli. That response (heart rate) in irregularly irregular.
The sinus node is specialized tissue that produces a very strong electrical signal ("p wave") at regular intervals (60-100). Measuring the distance between QRS complexes (ventricular response) is usually pretty regular with slight variation for respiration.
These are different sources of stimulation. "f waves" don't turn into "p waves"
"f waves" don't come and go as quickly as artifact does.

Here is an example of what? AF or AFL or Artifact. Note QRS complexes clearly defined. Looks to be SR but possible slightly irregularly irregular? Also PACs and PVCs in ECG.
Thanks for feedback!
