What else can I help you with?
What does ventricular repolarization result in?
contraction
What heart valve opens as a result of right ventricular contraction?
Pulmonary valve
Which wave length is larger atrial contraction or ventricular contraction?
the ventricular contraction wave is larger
What does inadequate ventricular systole mean?
It is a defective ventricular contraction.
Which wave is larger the one for atrial contraction or the one for ventricular contraction?
The wave for ventricular contraction is larger than the wave for atrial contraction. This is because the ventricles have thicker muscle walls and contract more forcefully in order to pump blood out to the body.
Why does the lub sound occur around the peak of the R wave?
The lub sound occurs around the peak of the R wave in an ECG because it is associated with closure of the mitral and tricuspid valves, which happens at the beginning of ventricular contraction. This coincides with the R wave, which represents ventricular depolarization and the onset of ventricular systole.
What is ventricular escape?
purkinjie fiber develops a rhythm of its own & ventricular contraction occur
The contraction of the ventricles is referred to as systole and the period of ventricular relaxation is called?
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Soon after the onset of the ventricular systole the?
AV valves close
What part of the ECG tracing occurs just as ventricular volume reaches 130 mL?
Just as ventricular volume reaches approximately 130 mL, the QRS complex on the ECG tracing occurs. This complex represents ventricular depolarization, which precedes ventricular contraction. At this point, the ventricles are filled with blood, leading to the onset of systole. The increase in ventricular volume correlates with the end of diastole, just before the heart pumps blood into the circulation.
What is the time interval of ventricular contraction?
0.3 seconds
What is a premature ventricular contraction is classified as a?
extrasystole.
