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 baseline on the EKG strip is considered to be the
Artifact is the medical term for deflection on the EKG not originating the in heart.
wandering baseline
The medical term for deflection on an EKG tracing caused by electrical activity other than from the heart is "artifact." This can be due to various external factors interfering with the EKG signal, such as patient movement, improper electrode placement, or electrical interference. It is important to recognize and address artifacts to obtain an accurate EKG interpretation.
wandering baseline
Baseline wander on an EKG (electrocardiogram) refers to the slow, undulating movements of the baseline of the tracing, which can obscure the detection of the heart's electrical activity. It is often caused by patient movement, breathing, or poor electrode contact. This artifact can lead to misinterpretation of the heart's rhythm and abnormalities if not recognized and corrected. Proper electrode placement and ensuring the patient remains still can help minimize baseline wander.
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.
If the maximum bending moment occurs at a point, then the corresponding deflection will also be maximum at that point. This is because the deflection of a beam is directly influenced by the bending moment acting on it. So, wherever the bending moment is greatest, the deflection will also be greatest.
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.

The resting height of the QRS deflection, also known as the baseline or isoelectric line, refers to the level of the electrocardiogram (ECG) trace when no electrical activity is occurring in the heart. It serves as a reference point for measuring the amplitude of the QRS complex, which represents ventricular depolarization. Ideally, the QRS complex should rise above this baseline during a normal heartbeat, indicating proper electrical conduction through the ventricles. Any significant deviation from this resting height can indicate underlying cardiac issues.
