Global T-wave inversion as seen on electrocardiogram is associated with a variety of pathophysiologic states, including cardiac, pulmonary, and cerebrovascular disease, and acute electrolyte disorders. Although some of these are chronic conditions, others are acute emergencies, necessitating early diagnosis and treatment. This article reviews and provides examples of possible etiologies of global T-wave inversion on electrocardiogram.

A 43-year-old male patient with no known past medical history presented to the emergency department with new-onset bitemporal headache, dizziness, and bilateral lower extremity weakness for 1 day. The patient denied chest pain, shortness of breath, cough, or recent exposure to sick individuals. He was not on any medications and denied alcohol or illicit drug use.

Background: Nonspecific electrocardiogram (ECG) findings are associated with increased morbidity and mortality in high-income settings. ECGs are increasingly available in emergency departments (EDs) in low- and middle-income countries (LMICs), however the prognostic value of nonspecific ECG findings in resource-limited settings, particularly in sub-Saharan Africa, remains unclear.
Objective: To assess the association between nonspecific ECG findings and 30-day mortality among patients presenting with chest pain and shortness of breath to a Tanzanian ED.

Objective: Treating iron deficiency (ID) with ferric carboxymaltose (FCM) in patients with heart failure with reduced ejection fraction (HFrEF) enhances morbidity, quality of life (QoL), and exercise capacity.
Methods: In the presented single-center, prospective follow-up study, symptomatic patients with HFrEF with ID and CIEDs scheduled for IV FCM were followed up for 12-months. Arrhythmic activity was evaluated from CIEDs and non-invasive markers from Holter recordings before and after FCM.

Background: The electrophysiological mechanism connecting mitral valve prolapse (MVP), premature ventricular complexes and life-threatening ventricular arrhythmia is unknown. A common hypothesis is that stretch activated channels (SACs) play a significant role. SACs can trigger depolarizations or shorten repolarization times in response to myocardial stretch.

Non-ST segment elevation acute coronary syndrome (NSTE-ACS) could behave like ST-segment elevation ACS in terms of causing total or near total occlusion of the coronary artery and leading to occlusive myocardial infarction (OMI). This study aims to assess OMI prevalence and associated factors in NSTE-ACS patients in Duhok, Iraq, to improve diagnosis and treatment outcomes.
