The typical ECG changes in tetralogy of Fallot are right axis deviation, large R waves in the anterior precordial leads and large S waves in the lateral precordial leads. We present a patient with extreme deviation of the frontal QRS axis between -90° and ± 180°. The child underwent open heart surgery twice before one year of age and a third time at nine years of age.

Subjects And Methods: We evaluated the long-term prognostic significance of acute phase frontal plane QRS-axis deviation and its shift during hospital stay in ACS patients. A total of 1026 patients who met the inclusion criteria were divided into three categories: normal (n = 823), left (n = 166) and right/extreme axis (n = 37).
Background: We aimed to determine the association of atrial fibrillation (AF) with 1-year outcome in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI).
Methods: Patients (n = 8830) enrolled in the rial f Routine Aspiration hrombectomy with PCI vs PCI one in Patients With STEMI (TOTAL) were followed for 1 year. The primary outcome was a composite of cardiovascular death, recurrent myocardial infarction, cardiogenic shock, or new or worsening class IV heart failure.
Article Synopsis
- Atrial fibrillation (AF) is common in acute coronary syndrome (ACS), and this study aims to assess its long-term mortality impact compared to sinus rhythm (SR) patients.
- The study involved 1,188 ACS patients over a median age of 73, finding AF patients were older, more often female, and had higher rates of comorbidities and medication use, particularly warfarin.
- Results show AF patients had significantly higher all-cause mortality (80.9% vs. 50.3%) and the study concludes that AF is an independent predictor of poorer long-term outcomes in ACS.
Background: A positive T wave in lead aVR (aVRT+) is an independent prognostic predictor of cardiovascular mortality in the general population as well as in cardiovascular disease.
Subjects And Methods: We evaluated the prognostic impact of aVRT+ in an ECG recorded as close to hospital discharge as possible in acute coronary syndrome patients (n = 527). We divided the patients into three categories based on the findings in the admission ECG: ST elevation, global ischemia and other ST/T changes.
