What else can I help you with?
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.
What is an s-p interval?
The s-p interval is a measure of time that reflects the duration between the onset of ventricular depolarization (measured by the ventricular conduction time, QRS complex) and the onset of ventricular repolarization (measured by the T wave). It is used in electrocardiography to help assess the electrical activity of the heart.
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.
What does a long QT interval on ECG mean?
It is a lengthening of the amount of time between depolarization of the ventricles of the heart, and the repolarization of the ventricles of the heart. The significance of this lies in the fact that the Q-T interval is a vulnerable time for the heart. Stimulation of the heart muscle during the relative refractory period (which is during the latter part of the Q-T interval) will cause a premature ventricular contraction, which may throw your heart into a dangerous dysrhythmia.
What does ventricular repolarization result in?
contraction
How many seconds does ventricular contraction last?
The normal time of ventricular contraction depends on the heart rate. The QT segment represents the ventricular contraction on an ECG exam. The corrected QT segment is 0.45 seconds for men and 0.46 seconds for women.
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.
What part of the ECG tracing represents the time from the start of the atrial activity to the start of ventricular activity?
QT interval
What would a premature ventricular contraction in which the QRS waves have the same configuration each time they appear be described as?
A group of premature ventricular contractions in which the QRS configuration is always the same are referred to as monomorphic premature ventricular contractions.
What is a premature ventricular contraction is classified as a?
extrasystole.
