Stimulation of this area with implanted electrodes results in increased heart rate and systemic vascular resistance due to increased sympathetic output. Axons from these nuclei descend to the sympathetic trunk via the intermediolateral columns of the spinal cord. From their synapses in cervical ganglia, postganglionic fibers directly innervate the atrial and ventricular musculature, the S-A node, and the A-V node.

The effector neurotransmitter is norepinephrine and the receptors are of the beta adrenergic type. There is evidence from competitive binding studies that the postganglionic fibers are predominantly associated with type I beta receptors. The parasympathetic influence to the S-A node and the myocardium originates from nuclei very near the origin of the sympathetic nerves. From the motor nuclei of the vagus and the nucleus solitarius come fibers that form part of the vagus nerve.

These fibers terminate at ganglia in the wall of the heart. The postganglionic cholinergic fibers end mostly near the S-A node and the A-V node; there is little evidence for the distribution of parasympathetic nerves to the ventricular myocardium although cholinergic muscarinic receptors have been characterized. In normal conditions there exists a well balanced autonomic tone influencing the S-A node. There is a complex interrelation among many systems to determine the autonomic tone at the S-A node Fig 2. New York, Raven Press, Visceral afferent inputs increase parasympathetic tone resulting in bradycardia.

Powering Decisions That Matter
Several reflexes are present for homeostasis. For example, the baroreflex is important in sensing changes in blood pressure and increasing or decreasing the heart rate via autonomic influences at the S-A node to maintain appropriate cardiac output. Arterial mechanoreceptors of the carotid sinus and aortic arch respond to changes in arterial pressure and result in appropriate adjustment in the sympathetic and vagal outflow to the heart and resistance and capacitance vessels. Although the importance of autonomic influence is well accepted in the usual cardioacceleration to exercise, the role of the recovery or deceleration of heart rate following exercise may not be influenced by autonomic input.

Six men were studied after peak treadmill exercise. To assess the contribution of autonomic factors in heart rate recovery, the men were given atropine, propranolol, or both agents. It was found that exponential cardio-deceleration occurred under each experimental condition. They concluded that heart rate recovery after exercise is regulated by changes in venous return mediated through atrial stretch receptors of pacemaker tissue.

This study implies that deceleration depends primarily on factors intrinsic to the intact circulation that are independent of autonomic control. The control of heart rate is complex; autonomic tone, central and peripheral reflexes, hormonal influences, and factors intrinsic to the heart are all important. Although easily measured, the heart rate reflects an integrated physiologic response. The physiologic response to exercise depends on the type of exercise performed; the two major types are isometric and isotonic. Creating muscle tension with no movement against resistance is a pure form of isometric exercise; this results in increased muscle mass and strength. Isotonic exercise is the repetitive, rhythmic movement of large muscle masses against little resistance, known also as dynamic or aerobic exercise. Although most activities involve degrees of both, running is predominantly dynamic, and weight lifting is predominantly isometric.

Bezucha and colleagues investigated the cardiovascular responses to isometric static exercise leg extension and compared these to those observed during static-dynamic exercise one arm cranking and dynamic exercise leg cycling in normal men. Cardiac outputs were raised in all three activities in a proportional manner: 6. Stroke volume did not significantly change in the static or combined static-dynamic exercises.

The increases in cardiac output were primarily the result of increases in heart rate. This study demonstrates the predominant pressor response and modest cardio-acceleration of isometric exercise. Longhurst and coworkers, examined the response to acute and chronic exercise in two groups of athletes who typify the two major types of exercise: long distance runners dynamic and weight lifters isometric. The runners responded to isometric exercise with lower double products than the weight lifters. The end-diastolic volume index evaluated by echocardiography in the runners was greater than control subjects both at rest and with exercise. Not only is the type of exercise an important determinant of acute physiologic response, but chronic static exercise results in physiologic responses that are no different from the responses of sedentary men. Dynamic exercise, also called isotonic or aerobic, involves the rapid movement of large muscle masses that results in the need for the body to respond with increased ventilation to increase oxygen consumption.

Such exercise is called aerobic since it must be performed by using oxygen. The heart must increase its output and performs flow work rather than pressure work. The response to dynamic muscular exercise consists of a complex series of cardiovascular adjustments designed to: 1 see that active muscles receive a blood supply appropriate to their metabolic needs; 2 dissipate the heat generated by active muscles; and, 3 maintain the blood supply to the brain and the heart. The regulation of the circulation during exercise involves the four following adaptations? This law states that resistance is proportional to pressure divided by flow. Peripheral resistance increases in the tissues that do not function in the performance of the ongoing exercise and decreases in active muscle.

The result is a decrease in systemic vascular resistance. While pressure only increases mildly, flow can increase by as much as five times during dynamic exercise. Since flow increases much more than pressure, the result is a decrease in systemic resistance. Another mechanical adaptation occurs when the increasing venous return dilates the left ventricle and cardiac function is enhanced via the Frank-Starling mechanism. There is a highly predictable relationship between total body oxygen consumption and both the cardiovascular and respiratory responses to exercise Fig 4.

An increase in heart rate is a major factor contributing to the exercise-induced increased cardiac output. Bowditch demonstrated that the time interval between beats is a determinant of the force of myocardial contraction. This has been called the frequency-force relationship Fig 5. A slow increase in isometric tension results from the change in rate implying in increased contractile state. Each vertical line represents an isometric contraction. Reprinted with permission of W. Although the mechanism of this phenomenon is not known, it may have to do with calcium availability to contractile elements. Thus an increase in heart rate results in an increase in the force of contraction. Irving, Robert A. Bruce,, Timothy A.

The majority of maximal systolic blood pressure readings were reported to the nearest centimeter rather than millimeter of pressure. Retesting of persons from 1 to 32 months later showed that pressure values agreed within 10 percent in two thirds, the overall mean difference was only 8. Hypertensive patients had a significantly greater body weight than normotensive persons.

Moreover, it has mandated that by , wireless carriers in the USA deliver a usable location for callers 80 percent of the time. But that means that in six years, communication centers hypothetically may still be unable to locate one in every five callers. Yet the silver lining in all of this may be that the root of the problem technology may also be its solution. Rapid advances in technology created a 21st century smartphone society that no longer adheres to the old rules where landlines have corresponding physical addresses available to calltakers. But what if that same wave of cutting-edge technology development resulted in some innovative options to crack the caller location enigma?

The matrix of more than 8, coordinates was entered into a computer-aided dispatch CAD system as a commonplace database. All golf courses were contacted seeking their participation by displaying provided posters and were asked to encourage golfers if they have an emergency on the course to dial on a cellphone rather than call the clubhouse. Calling the clubhouse only delays the critical response.
