If decelerations are associated with tachysystole consider terbutaline 0. Variable Decelerations Vagally mediated through chemoreceptors or baroreceptors. Accelerations "shoulders" before and after a variable deceleration are thought to be caused by partial cord occlusion. Decreased venous return causes a baroreceptor-mediated acceleration. Hypertension and decreased arterial oxygen tension secondary to complete cord occlusion results in deceleration. Variables occur with head compression secondary to vagal nerve activation, and with movement in the premature fetus The timing of the deceleration may occur periodically either with or after the contraction .
Tension[ edit ] It corresponds to diastolic blood pressure. A low tension pulse pulsus mollis , the vessel is soft or impalpable between beats. In high tension pulse pulsus durus , vessels feel rigid even between pulse beats. Form[ edit ] A form or contour of a pulse is palpatiory estimation of arteriogram. A quickly rising and quickly falling pulse pulsus celer is seen in aortic regurgitation. A slow rising and slowly falling pulse pulsus tardus is seen in aortic stenosis.
What is a Heart Rate? Heart Rate or HR is simply the number of times your heart beats in a unit time or a minute. Alternatively known as pulse, heart rate differs from people to people, depending on their age, genetics, lifestyle, and fitness levels.
A normal resting heart rate is between 60 to beats per minute. Essentially, the lower the resting heart rate is the more efficient your heart functions. A low resting heart rate is also a signifier of better cardiovascular fitness.
