2024年10月8日 · Three broad categories of lateral infarction: Anterolateral STEMI due to LAD occlusion. Inferior-posterior-lateral STEMI due to LCx occlusion. Isolated lateral infarction due to occlusion of smaller branch arteries such as the D1, OM or ramus intermedius. High Lateral STEMI. ST elevation is present in the high lateral leads (I and aVL).

2017年4月2日 · LCX occlusions are an underdiagnosed clinical entity in ACS management. Despite non-diagnostic ECG findings, total LCX occlusion should be considered in clinical presentations consistent with ACS. If the patient appears clinically worse than the ECG findings would suggest, consider discussing with interventional cardiology about pursuing PCI ...

Occlusion in the left circumflex coronary artery (LCx) Areas supplied by the left circumflex coronary artery. In 90% of individuals, the coronary circulation is right-dominant, meaning that the PDA is given off by the RCA. In these individuals, the LCx only supplies the basal and mid parts of the posterolateral wall.

2024年10月8日 · The LCx territory covers the lateral part of the inferior wall and the left posterobasal area. The injury current in LCx occlusion is directed inferiorly and leftward, producing ST elevation in the lateral leads I and V5-6; These differences allow for electrocardiographic differentiation between RCA and LCx occlusion.

Acute coronary syndrome (ACS) with occlusion of the left circumflex coronary artery (LCX) poses diagnostic problems that may lead to a delay in reperfusion. From a group of 1,269 consecutive patients with ACS, 138 patients with ACS due to LCX ...

Left circumflex coronary artery (LCX) In 90% of individuals, the coronary circulation is right-dominant, meaning that the PDA is given off by the RCA. In these individuals, the LCx only supplies the basal and mid parts of the posterolateral wall.

2015年12月23日 · Following ECG features help localize Inferior STEMI . ST depression in lead V1,V2,V3 strongly suggest LCX. (More objectively the sum of ST depression in V1, 2 , 3 divided by sum ST elevation in 2,3, AVF , if less than 1 indicate LCX. Or simply ST depression V3 > Lead 3 indicate LCX.)

2024年3月1日 · Diagnosis of left circumflex artery (LCx) myocardial infarctions via 12‑lead electrocardiogram (ECG) has posed a challenge to healthcare professionals for many years. A retrospective observational study was performed to analyze …

To assess the characteristic electrocardiographic (ECG) ST changes during acute occlusion of the left circumflex artery (LCX), we observed ECG changes during percutaneous transluminal coronary angioplasty (PTCA) of the LCX and compared the results with those obtained during right coronary angioplast …

2001年7月24日 · Four previously described criteria were useful in identifying the right coronary artery (RCA) or the left circumflex coronary artery (LCX) as the culprit: ST-segment elevation in lead I, ST-segment more or less elevated in lead II than in lead III, ST-segment elevation ≥ 0.5 mm in lead V 4 R, and various combinations of ST-segment elevation ...
