Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
What is the time taken by atrial systole and ventricular systole?
0.4sec
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
Would yo be able to feel a pulse during atrial systole only?
yes because during atria systole, the heart muscle tissue contracts.
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.
During atrial systole 70 percent of ventricular filling occurs?
No. Most (~70%) of ventricular filling occurs passively, without atrial contraction.
Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
Who comes first atrial systole or ventricle systole?
Atrial systole -- The atrium contracts, then the ventricle.
What is the time taken by atrial systole and ventricular systole?
0.4sec
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
Would yo be able to feel a pulse during atrial systole only?
yes because during atria systole, the heart muscle tissue contracts.
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 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.
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).
Does atrial systole occur before or after the firing of the sinoatrial node?
The SA node makes the action potential for the heart. Atrial systole must occur after the action potential.
Is systolic pressure where the ventricls are relaxing?
Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
What is atrial repolarization indicated by?
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
