Abstract

CE credit: For CE credit, you can access the test for this article, as well as additional JNMT CE tests, online at https://www.snmmilearningcenter.org. Complete the test online no later than December 2018. Your online test will be scored immediately. You may make 3 attempts to pass the test and must answer 80% of the questions correctly to receive 1.0 CEH (Continuing Education Hour) credit. SNMMI members will have their CEH credit added to their VOICE transcript automatically; nonmembers will be able to print out a CE certificate upon successfully completing the test. The online test is free to SNMMI members; nonmembers must pay $15.00 by credit card when logging onto the website to take the test.The nuclear medicine technologist works with electrocardiography when performing cardiac stress testing and gated cardiac imaging and when monitoring critical patients. To enhance patient care, basic electrocardiogram interpretation skills and recognition of key arrhythmias are essential for the nuclear medicine technologist. This article provides insight into the anatomy of an electrocardiogram trace, covers basic electrocardiogram interpretation methods, and describes an example case typical in the nuclear medicine environment.

Electrocardiographic abnormalities to the patients infected with HIV/AIDS under antiretroviral tritherapy at the University Clinics of Kinshasa

“…This observation remains lower than that of Bloom eld G et al [17]who found 44% of PLHIV/ART with ECG abnormalities, dominated by prolonged QTc in men (9% versus 6%, p = 0.001) and 18.2% for Njoku PO et al [21]On the other hand, ST/T wave abnormalities have been associated with the risk of developing ventricular tachycardia, myocardial ischemia, myocardial infarction, and abnormal ventricular repolarization. Tso C et al [22], Suleiman et al [23] reported that ST/T abnormalities, in particular, can be predictive of CVD in PWH and highlighted the prognostic value of ST/T changes in HIV + patients.…”

HIV and Antiretroviral Therapy Are Independently Associated with Cardiometabolic Variables and Cardiac Electrical Activity in Adults from the Western Cape Region of South Africa

“…Our findings support the results of a study by Ding et al [ 24 ], who showed that ST/T wave abnormalities were positively associated with HIV infection, ACR, Hb, fasting glucose and longer duration of HIV infection (≥3 years). ST/T wave abnormalities have been associated with the risk of developing ventricular tachycardia, myocardial ischaemia, myocardial infarction, and abnormal ventricular repolarisation [ 25 ]. This finding, however, contradicts Ding et al [ 24 ], who reported significant associations between blood pressure categories and ventricular abnormalities (ST/T abnormalities) in their HIV− group instead.…”

IoT-based health information system using MitApp for abnormal electrocardiogram signal monitoring

“…The main components of the EKG signal include the P wave, QRS complex, and T wave. The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization [28]. To identify the ECG signal image, an ECG electrode lead is needed, which is then processed through the Arduino Uno microcontroller and displayed on the nection TFT display screen.…”
