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).
What is a heart contraction?
it is also known as systol
What is atrial repolarization indicated by?
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
When was atrial septal defect diagnosed?
during the preschool years
During atrial systole 70 percent of ventricular filling occurs?
No. Most (~70%) of ventricular filling occurs passively, without atrial contraction.
What percent of blood pass from the atria to the ventricles before the atrial walls contract?
70% the remaining 30% is pushed into the ventricles during atrial systole
What happens to the volume of blood in the ventricle during the period of isovolumetric contraction?
Both ventricular contraction and atrial diastole take place.
Difference between atrial fibrillation and atrial flutter?
They're he same thing. Atrial flutter is more of a slang term, and is sometimes found in patients with atrial tachycardia. Basically, atrial fibrillation is a disorder, and atrial flutter is a symptom
What happens with atrial flutter?
Atrial flutter-- Rapid, inefficient contraction of the upper chamber of the heart.
What are ventricles doing atrial systole?
During atrial systole, the SA node ( power house for heart to keep on beating) is unable to send signals to ventricles. But heart has some back up power houses which take over, so the ventricles can still keep on beating but at a slower rate than normal during atrial asystole.
What would happen if atrial contraction occurred early?
Nothing significant happens... intensity of S1 might decrease
What does atrial drop dirty for?
Can I drop derty for atrial
