Many physicians recommend EKGs as a preventative-screening tool for those with a family history of heart disease. While a healthy person does not need an EKG as a part of an annual exam Josh Manson Ducks Jersey , many physicians will recommend an EKG if they have concerns. If a patient complains of chest pain, palpitations or other indicators of heart problems, the physician will likely recommend an immediate EKG test. Depending on the severity of the situation, your doctor may refer you to a local testing center immediately or ask you to schedule the next available appointment. An abnormal EKG is determined by comparing the results of your EKG graph with a standard or normal heart graph. Spikes and dips within the graph are referred to as P, QR and PR and other similar acronyms. Normal EKG readings show a slight flat-dip in between contractions and relaxations. If these flat-dips are not present, it may be an indication of a more serious problem. Normal EKG readings will have spikes and dips too.Myocardial defects Derek Grant Ducks Jersey , heart valve disease, enlargement of the heart, inflammation of the heart, coronary artery disease, and past, pending or impending heart attacks are only a few of the problems that EKG茂驴陆s can help to detect. The conditions in which the EKG is performed can also have an impact on the accuracy of the results. Some heart problems are not present all of the time and therefore may not appear in EKG results. In cases where heart problems are suspected but not detected on the EKG John Gibson Ducks Jersey , a Holter monitor may be recommended. This monitor is worn, usually for a period of 24 to 48 hours and serves as a type of mini-EKG test. The patient wears the monitor at home and it continuously records heart activity. Doctors also recommend that the patient be relaxed during the exam because any muscle trembling or contractions can alter the results and produce an inaccurate reading. Many people are surprised to learn that they have had an abnormal EKG reading. What is even more surprising is that when presented with abnormal EKG results, some doctors do not seem concerned. It doe not necessarily mean they are inadequate or uncaring physicians, it is more likely they believe something else has caused the abnormal reading. Most will want to pursue further testing or another EKG. Sometimes an event as simple as low blood sugar can have an altering affect and produce false EKG readings. Other times, abnormal EKGs require further testing to determine what, if any Jakob Silfverberg Ducks Jersey , problems actually exist.

WASHINGTON, Dec. 18 (Xinhua) -- Although a new round of U.S. sanctions against Russia might not have a direct impact, they could increase Russia's sense of panic and ratchet up pressure on the country's embattled economy, experts said.

U.S. President Barack Obama on Thursday signed into law a new round of sanctions against Russia, but for now, does not intend to use them Ryan Miller Ducks Jersey , saying the administration is keeping an eye on the situation in Ukraine.

"My administration will continue to work closely with allies and partners in Europe and internationally to respond to developments in Ukraine and will continue to review and calibrate our sanctions to respond to Russia's actions," Obama said in a statement, adding that he was prepared to roll back sanctions should Russia take the necessary steps.

Russia's economy has for months been flailing amid a falling currency and Western sanctions over the crisis in Ukraine. Energy prices have also fallen, dealing a severe blow to the Russian economy, as oil and gas industry comprises around 50 percent of its revenue. Earlier this week saw the sharpest drop in the ruble in 16 years.

While it is unclear whether the new sanctions would have a direct impact on Russia, the anticipation alone is enough to give investors the jitters Brandon Montour Ducks Jersey , and that could in turn lead to even more economic turmoil in the embattled country, experts said.

Indeed, the greatest effect of sanctions has not been from the sanctions themselves but rather the broader effect of leaving investors, Russian and foreign, nervous about the Russian economy, leading to capital flight Ondrej Kase Ducks Jersey , RAND Corporation Senior International Policy Analyst Olga Oliker told Xinhua.

"The limits that the sanctions have placed on Russia's access to capital markets have been very important, but general investor skittishness, over and above the sanctions, has been more important, and stands to last indefinitely," she said.

The White House is keeping an eye on the situation Adam Henrique Ducks Jersey , with White House spokesman Josh Earnest saying earlier this week that the administration has "suggested the longer the sanctions regime is in place, the more isolated the Russians would be and the greater the impact it would have on the broader Russian economy."

"And every week and month that goes by that the sanctions regime is in place, we see that the toll that is being taken by the Russian economy grows," he said.

From Russian President Vladimir Putin's annual press conference on Thursday, it is not clear that Russia has a plan for the beleaguered economy. Putin said that it may take a couple of years for Russia's economy to get back on track, which might mean he was betting on a rise in the price of oil Rickard Rakell Jersey , the eventual lifting of sanctions, or both.

Whether the situation will affect Russia's policy in Ukraine remained to be seen, Oliker said.

Meanwhile, it remained unknown how the Obama administration would move to implement the sanctions. There is some leeway, in that the administration can choose among the menu of sanctions enumerated in the language of the act, and have some time to make decisions Antoine Vermette Jersey , Oliker said.

U.S.-Russia relations are at a low point not seen for more than a decade, with the crisis in Ukraine causing a major rift between the United States and Russia. But chilled ties are unlikely to plunge the world headlong into another Cold War, experts said.
