The baseline on the EKG strip is considered to be the
wandering baseline
The "R" is the greatest deflection from the baseline on the ECG. The R is part of the QRS complex. This complex represents ventricular depolarization in the heart.

The P wave represents atrial depolarization (they contract). In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline.
What is baseline wander ? The severity of the baseline wander is dependent on the HPF cut-on frequency and the PSD of the signal around DC. The output of the high-pass filter will have equal areas (a=b) above and below zero volts. If the pulse repetition frequency is low compared with the time constant of the input circuit, we'll see some "droop" in the waveform, indicating the discharging of the input capacitor
"No wander" does not mean anything in Spanish. At best it is a bastardized form of the English command "Do not wander".

Baseline wander and power line interference can be effectively removed using digital filtering techniques. A common approach is to apply a high-pass filter to eliminate low-frequency baseline wander and a notch filter to target and attenuate specific power line frequencies (typically 50 or 60 Hz). Additionally, techniques like wavelet transform or adaptive filtering can also be employed for more complex signal conditions. These methods help to enhance the quality of the signal for better analysis and interpretation.
Close to normal, but not quite.
The straight line on an EKG is called the isoelectric line. It represents the baseline electrical activity of the heart when there is no depolarization or repolarization occurring. Deviations from this line indicate electrical activity associated with heartbeats, such as P waves, QRS complexes, and T waves.
