The Mother and Her Child This allows more blood to enter the left ventricle, and the left ventricle, acting perfectly on the blood which it receives, causes a good systolic pressure in the aorta and the systemic arteries. Disturbances of the Heart When the systolic pressure is gradually falling and the diastolic remains the same, the circulation is failing and unless the pulse pressure can be established again the patient will die. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z The diastolic pressure drops back nearly to normal and the increased pulse pressure is due almost entirely to the slight rise in the systolic pressure.

Disturbances of the Heart If a patient has hypotension and a systolic pressure of 110, and is given nitroglycerin, the very unpleasant results from its administration will be immediately noticed. Disturbances of the Heart When, after some minutes of repose, he assumes the erect posture again, the systolic pressure will diminish and the diastolic pressure increase, and the pressure pulse shortens. Disturbances of the Heart In aortic regurgitation this low diastolic pressure is constantly in evidence, and, if the systolic pressure is not below normal, does not signify that the circulation is insufficient. Disturbances of the Heart It should be constantly borne in mind, that the systolic pressure reading which is made, is the maximum effort of the heart at that moment only. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z If the systolic pressure is not very low but the diastolic is high, vasodilator drugs, by lowering the diastolic and increasing the pulse pressure, are often of benefit. Disturbances of the Heart The strenuous measures that should he used to lower a high diastolic pressure are contraindicated when the diastolic pressure is already low, even if the systolic pressure 1s high. Disturbances of the Heart He also found that a lower systolic pressure with a lower diastolic pressure is not a sign that the heart is weakening, but only that the visceral tone is growing less. Disturbances of the Heart If a high systolic pressure begins to fall more or less rapidly the heart shows fatigue, and should be stimulated by digitalis or strophanthin. Disturbances of the Heart It is more stable than the systolic pressure, subject to fewer more or less unknown influences. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z If the heart becomes weak the systolic pressure will drop, and any improvement caused, especially in aortic regurgitation, is by an increase of the systolic pressure. Disturbances of the Heart If, after this slight exercise in the erect posture, the systolic pressure is diminished, the heart muscle is defective. Disturbances of the Heart When there is circulatory defect or abnormal blood pressure, exercise may not increase the systolic pressure, and the pressure pulse may grow smaller. Disturbances of the Heart They found that "low systolic pressures are not invariably of evil omen." Disturbances of the Heart Formerly I believed that all high systolic pressure cases were cases of chronic nephritis of some definite degree. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z On the other hand, a high systolic pressure without a high diastolic pressure should not be rapidly lowered, else depression will be caused. Disturbances of the Heart While he believes that a systolic pressure of over 160 mm. is pathologic, he does not find that any definite prognostic conclusions can be drawn from the height of the pressure. Disturbances of the Heart Then reduce the pressure 5 mm. and read again for a minute, and so on down the scale until the varying systolic pressures are recorded. Disturbances of the Heart In some persons the auscultatory readings cannot be made, or are very unsatisfactory, and it becomes necessary to use the palpation method in taking the systolic pressure. Disturbances of the Heart At the time of perforation the systolic pressure may be raised. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z He also should not watch the dial, as any tensity on his part more or less raises the systolic pressure, the diastolic not being much affected by such nervous tension. Disturbances of the Heart Eighty-five of these young men, however, had a systolic pressure of over 140. Disturbances of the Heart On the other hand, it is now generally proved that persons with overweight have a systolic pressure greater than is normal for individuals of the same age. Disturbances of the Heart Of course it should be recognized that the systolic pressure thus obtained will generally be some millimeters above that obtained with the finger, perhaps the average being equivalent to about 5 mm. of mercury. Disturbances of the Heart Aortic insufficiency also may be accompanied by a high systolic or by a normal systolic pressure. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z The first phase begins with the first audible sound, which is the proper point at which to read the, systolic pressure. Disturbances of the Heart The right arm of right handed persons usually registers a full 5 mm. higher systolic pressure than the left arm. Disturbances of the Heart The pressure pulse, therefore, increased progressively with the increase of the systolic pressure. Disturbances of the Heart With normal heart and arteries, exertion and exercise should increase the systolic pressure, and generally somewhat increase the diastolic pressure. Disturbances of the Heart The systolic pressure represents the maximum force of the heart. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z In an irregularly acting heart the systolic pressure may vary greatly, from 10 to 20 mm. or more, and a ventricular contraction may not be of sufficient power to open the semilunar valves. Disturbances of the Heart If the systolic pressure is low and the diastolic very low, or when the heart is rapid, circulation through the coronary vessels of the heart is more or less imperfect. Disturbances of the Heart A rising blood pressure in pregnancy, when associated with other toxic symptoms, is indicative of danger, and Evans believes that a systolic pressure of 160 mm, is ordinarily the danger limit. Disturbances of the Heart It is not unusual to find that a young man who is very athletic has an abnormally high systolic pressure. Disturbances of the Heart Physiologically there are many conditions which modify the systolic pressure. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z In 52 percent of these 211 persons the systolic pressure was under 140, while in the remaining 48 percent it ranged from 145 to 200 mm. Disturbances of the Heart The systolic pressure varied from 91 mm. in the fourth year to 105.5 in the fourteenth year, while the diastolic pressure remained almost at a uniform level. Disturbances of the Heart He gives it hypodermically, 15 minims at the first dose and 5 minims subsequently, until the systolic pressure is reduced to 140 or less. Disturbances of the Heart On the other hand, too low a systolic pressure in an adult, 105 mm. or below, should cause suspicion of some serious condition, the most frequent being a latent or quiescent tuberculosis. Disturbances of the Heart The diastolic pressure is not very variable; it is not subject to the same influences which disturb the systolic pressure. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z When the systolic pressure is above 130, the patient should be carefully watched, and he thinks that 150 is the danger line. Disturbances of the Heart He finds that if a patient is past the eighth month, rupture of the membranes will usually bring a rapid fall of from 50 to 90 points in systolic pressure. Disturbances of the Heart A low systolic pressure and a low diastolic pressure may not cause any symptoms or give any cause for anxiety. Disturbances of the Heart In cardiac failure, as the systolic pressure falls the diastolic is likely to be increased, and the pressure pulse thus diminishing, allows insufficient blood to go to the medullary centers, and death soon occurs. Disturbances of the Heart Following exercise the pulse rate increases, the systolic pressure rises greatly, the diastolic slightly or not at all. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z A heart which is already enlarged or slightly dilated and insufficient, under the stress of muscular labor will more slowly increase its forcefulness, and we have the delayed rise in systolic pressure. Disturbances of the Heart If the heart muscle is in good condition, the systolic pressure should remain the same after this slight exertion and these changes in posture. Disturbances of the Heart If there is a low systolic pressure and a high diastolic pressure, this shows impairment of the heart, whether or not any other organic lesion is present. Disturbances of the Heart However, it should be again urged in making insurance examinations that psychic disturbance or mental tensity very readily raises the systolic pressure. Disturbances of the Heart For this figure the place on the scale where most of the beats are heard may be taken for the average systolic pressure. Arteriosclerosis and Hypertension: with Chapters on Blood Pressure, 3rd Edition. 2011-10-11T02:01:07.890Z This increased systolic pressure is the greatest about half an hour after a meal, and then gradually declines until the next meal. Disturbances of the Heart This is not to state that every high tension must be lowered, but every hypertension must be studied and a safer systolic pressure caused if it is possible without interfering with the person's efficiency. Disturbances of the Heart Generally speaking, a low systolic pressure shows a weak acting heart muscle, and a very low diastolic pressure shows a dilated condition of the arterioles.
