![]() journal self-citations removed) received by a journal's published documents during the three previous years.Įxternal citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents. Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.Įvolution of the number of total citation per document and external citation per document (i.e. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.Įvolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values. Your heart rate and blood pressure are monitored during the test.The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. ![]() Once the probe is in position, the physician is able to visualize your heart valves and the chambers of your heart. The nurse at the Hospital will prepare you for the test and start an intravenous line (I.V.) After sedation, the physician will insert a tube, called a probe, through your mouth into the esophagus. ![]() This allows your doctor to get more detailed pictures of your heart. The tube is guided down your throat and into your esophagus. This test is particularly helpful to see signs of clots or tumors inside the chambers of the heart, and to see the severity of any valve defects.ĭuring this test, the transducer is attached to the end of a flexible tube. If your doctor needs a better look at these areas, he or she may recommend transesophageal echo (TEE). With standard transthoracic echo, it can be hard to see the aorta and other parts of your heart. Similar to the standard stress echo, with a pharmacologic stress echo, the doctor or technician will take pictures of your heart before and after the medication is administered. If you aren't well enough to exercise, a technician may perform a pharmacologic stress test instead, which means your doctor will give you medication to make your heart work harder without you having to exercise. A technician will take pictures of your heart using echo before you exercise and as soon as you finish. During a stress test, you exercise to make your heart work hard and beat fast. Stress echo is done as part of a stress test. ![]() Some heart problems, such as coronary heart disease, are easier to diagnose when the heart is working hard and beating fast. ![]() This test is used to detect abnormal heart valve function and poor pumping function of the heart, and to identify blood clots within the heart chambers or tumors in the heart. As the ultrasound waves bounce off the structures of your heart, a computer in the echo machine converts them into pictures on a screen. The device sends special sound waves, called ultrasound, through your chest wall to your heart. The technician will ask you to turn onto your left side, and will apply a warm gel to the device before applying it to the skin over your chest. You will have some sticky pads (electrodes) applied to your chest and connected to a machine. "Noninvasive" means that no surgery is done and no instruments are inserted into your body. Transthoracic echo is the most common type of echocardiogram test. NewYork-Presbyterian Brooklyn Methodist Hospital's board certified cardiologists and certified technicians conduct several types of echocardiography ("echos") to create images of the heart, and unlike X-rays and some other tests, an echo doesn't involve radiation. ![]()
