yes
Causes for poor ECG tracing can be from the patient moving or interferences from electrical appliances in the room: cell phones, a lamp plug in etc
The ECG wave tracing represents the electrical activity of the heart as it beats. It shows the depolarization and repolarization of the heart muscle, which corresponds to specific events in the cardiac cycle. The different waves and intervals on the ECG tracing provide information about the heart's rhythm, rate, and potential abnormalities.
ECG tracing, or electrocardiogram tracing, is a graphical representation of the electrical activity of the heart over time. It records the heart's rhythm and can indicate issues such as arrhythmias, heart attacks, and other cardiac conditions. The tracing consists of waves, intervals, and segments that correspond to different phases of the cardiac cycle, allowing healthcare professionals to assess heart function and diagnose potential problems.

The deflection waves in an ECG tracing include the P wave (atrial depolarization), QRS complex (ventricular depolarization), and T wave (ventricular repolarization). Each of these waves represents different electrical activity of the heart during a cardiac cycle.
the repolarization of the atria is hidden by the QRS wave
yes
Why is it important that the eck tracing be handled carefully and not be allow to smear or be folded in any way
P wave
The horizontal part of a tracing on an ECG is called the baseline. It represents the period when the heart is not actively depolarizing or repolarizing, showing the electrical activity at rest.
In an ECG reading for atrial fibrillation (AFib), there will be irregular and rapid electrical signals in the atria, leading to a chaotic heart rhythm. This is shown as erratic waves on the ECG tracing. In a normal ECG reading, the heart's electrical signals follow a regular pattern, resulting in a steady and organized heart rhythm with distinct waves on the ECG tracing.
the T wave, which indicates ventricular repolarization
