What else can I help you with?
The portion of the ECG tracing between the QRS complex and the T wave is called the?
ST segment
What term is used to describe the horizontal part of a tracing on an ECG and what does this line indicate?
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.
What does a segment of an ECG tracing indicate?
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
Possible causes of a poor ECG tracing?
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
Which of the following results in extraneous marks on the ECG tracing?
Paperclips
Will a 60 cycle appliances interfere with a ECG tracing?
yes
What does the ecg wave tracing represent?
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.
In a normal ECG tracing?
the repolarization of the atria is hidden by the QRS wave
Does the atrial rate equal the ventricular rate in the ECG tracing?
yes
Why is it important that the ECG tracing be handled carefully?
Why is it important that the eck tracing be handled carefully and not be allow to smear or be folded in any way
What contraction of the atria results from which wave of depolarization on the ECG tracing?
P wave
What is baseline in ECG?
Baseline in an ECG refers to the flat line that represents the absence of electrical activity in the heart. It serves as a reference point for the peaks and valleys of the ECG waveform. Any deviation from the baseline may indicate abnormal electrical activity in the heart.
