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 does a segment on an ECG tracing indicate?
A segment on an ECG tracing represents a specific period of electrical activity in the heart, typically reflecting the time between different phases of the heart's electrical cycle. For example, the PR segment indicates the time it takes for electrical impulses to travel from the atria to the ventricles, while the ST segment represents the period between ventricular depolarization and repolarization. Analyzing these segments helps diagnose various cardiac conditions and assess overall heart health.
What does a segment on an electrocardiograph tracing indicate?
A segment on an electrocardiograph (ECG) tracing represents a specific period of electrical activity in the heart. It typically refers to the flat portions between waves, such as the PR segment or ST segment, and indicates the time taken for electrical impulses to travel through the heart's conduction system. These segments are crucial for assessing the heart's electrical stability and diagnosing various cardiac conditions. Changes in segments can indicate issues like ischemia or arrhythmias.
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.
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
