potential (pacemaker potential). Thus‚ the pacemaker potential is what drives the self-generated rhythmic firing. This is known as cardiac muscle automaticity.[2] Pacemaker potentials are fired by sinoatrial node (SAN)‚ but also by the other foci. However‚ the last ones have firing frequencies slower than the SAN’s. When other foci attempt to fire at their intrinsic rate‚ they can’t because they have been discharged by the previous electric impluse coming from the SAN before their pacemaker potential

MUSCULOSKELETAL FRACTURES ● Fracture is a disruption or break in the continuity of the bone structure. ● Traumatic injuries account for the majority of fractures. ● Fractures can be classified as displaced (open) or nondisplaced (closed) depending on communication or noncommunication with the external environment. ● Signs include immediate localized pain‚ decreased function‚ and inability to bear weight or use affected part. Obvious bone deformity may be present. ● Bone goes through eight stages of selfhealing (union)

ACKNOWLEDGMENT It gives me an immense pleasure in presenting this case study‚ which is made for the partial fulfillment of the requirement for the fourth year of B.Sc. Nursing Programme. We were provided 8 weeks of the clinical practice‚ at Shahid Gangalal National Heart Center. During our 8 weeks of clinical exposure each student had to do a detailed study of one cardiac problem. During my clinical exposure to Coronary Care Unit (CCU) for 1 week I got an opportunity to take case for study. We

the sinus node are called Normal Sinus Rhythm (NSR)‚ Sinus Bradycardia‚ Sinus Tachycardia‚ and Sinus Arrhythmia. Normal Sinus Rhythm is fairly easy to understand due to the pacemaker impulse‚ which originates in the sinus node and travels through the normal conduction pathways within normal time frames. Because the pacemaker originates in the sinus node and the conduction is normal‚ the P waves are uniform and will have a P wave for each QRS complex. Due to it being a Normal Sinus Rhythm the heart

partner was calm resulting in the blood pressure to be around 125/59 with 55 beats per minute. The second time we did it‚ the numbers were fairly similar 126/59 and 62 beats per minute. At the beginning there is no action potential occurring or the pacemaker is not racing to make the heart beat quicker because the body is not using much energy since it is basically at a resting state. You can detect the heart beats by using the QRS EKG method where each one can represent a heartbeat that has occurred

These short-block castings are used to build the R-208 engines for the tractor. Due to the defects that were found‚ the short-blocks need to be disassembled in order to be repaired. Each short-block would cost around $1550-$1700‚ depending on the supplier. The purchasing manager‚ James Sun‚ recently released an RFQ for short-block to three different companies that supplies assembled tractor engines. Among the three companies‚ only one was interested‚ which was ACE Manufacturing Inc. ACE is a small

In the field of medical device sales there is a vast number of providers for any medical device. Therefore‚ doctors are able to choose whatever provider they wish to use. As for the competiveness of cardiovascular devices‚ mainly pacemakers‚ there is no one company that has a sustainable competitive advantage. The device features are similar between companies. The worst thing a device company can do in this competitive market is fall behind in the latest technology or have any complications such

feet in Orlando‚ Florida. Like many other hospitals‚ and other companies‚ Arnold Palmer Hospital had been a long-time member of a large buying group‚ one servicing 900 members. But the group did have a few limitations. For example‚ it might change suppliers for a particular product every year (based on a new lower-cost bidder) or stock only a product that was not familiar to the physicians at Arnold Palmer Hospital. The buying group was also not able to negotiate contracts with local manufacturers to
