Objective To observe pulsative index (PI), resistant index (RI) of placental helicine arteries by colour Doppler, analyses relation between PI, RI and developing of pregnant hypertension.
Your body floods that area with blood to try and return it to body temperature and in the process your blood vessels expand, which causes that throbbing pain.
" Pass me a bowl, " said Hermione, holding the pulsating pod at arm's length; Harry handed one over and she dropped the pod into it with a look of disgust on her face.
In rare situations, an ectopic focus can trigger ventricular tachycardia or even ventricular fibrillation, which are more serious arrhythmias where the ventricles beat too quickly to fill up with an adequate amount of blood.
He linked the past with the present, and the eternity behind him throbbed through him in a mighty rhythm to which he swayed as the tides and seasons swayed.
She noticed that a type of star known as a Cepheid variable (after the constellation Cepheus, where it first was identified) pulsated with a regular rhythm-a kind of stellar heartbeat.
Again, again–and it was not the ear that heard the pulsing rhythm, it was the midriff; the wail and clang of those recurring harmonies haunted, not the mind, but the yearning bowels of compassion.
A normal ejection fraction is around 50-70%, between 40-50% would be borderline, and anything about 40% or less would indicate systolic heart failure because the heart is only squeezing out a little blood each beat.
But do I desire unreasonably much in wanting what is called life—music, poetry, passion, war, and all the beating and pulsing that are going on in the great arteries of the world?
If the premature ventricular contractions keep happening or cause palpitations, they can be treated with beta blockers or calcium channel blockers, both of which prevent the heart from beating too strongly.
This so-called " group beating" can be differentiated from a type 1 second-degree atrioventricular heart block by identifying the abnormally shaped p-waves that are characteristic of an atrial ectopic focus.
If the heart is beating fast enough, the p-wave from the premature atrial contraction might happen at the same time as the t-wave from the previous, normal contraction.
