Does the atrial rate equal the ventricular rate in the ECG tracing?
yes
On an electrocardiogram tracing atrial activity is represented by the?
p wave
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
What is the correct order of ECG waves?
P wave - represents atrial depolarization (contraction) QRS complex - ventricular depolarization T wave - ventricular repolarization (relaxation) atrial repolarization is "buried" within the QRS Complex
What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
Which would produce the most life-threatening condition atrial flutter ventricular flutter atrial fibrillation or ventricular fibrillation?
Ventricular fibrillation, since this pumps blood to the rest of the body.
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.
During atrial systole 70 percent of ventricular filling occurs?
No. Most (~70%) of ventricular filling occurs passively, without atrial contraction.
Which wave length is larger atrial contraction or ventricular contraction?
the ventricular contraction wave is larger
What are the major types of arrhythmia?
Atrial Fibrillation, Ventricular tachycardia, Ventricular fibrillation, Supraventricular tachycardia
Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
