Lateral infarction:堵塞的是left circumflex artery,记心电导联的位置:left lateral leads I, aVL, V5, and V6。 Anterior infarction:堵塞的是left anterior descending (LAD) artery。记心电导联位置:V1-6。而它的心电图有个标志:呈poor R-wave progression样。 In normal hearts, the amplitude of the R wa...
is the appearance of “hyperacute T waves” — T waves that appear peaked and are related to localized hyperkalemia. These changes are rarely detected, as they are transient and frequently occur prior to hospital arrival. The tracing below shows hyperacute T-wave changes in the ant...
Anterior STEMI: A blockage in the artery supplies blood to the front wall of the heart, the left anterior descending (LAD) artery.4 Inferior or Lateral STEMI: A blockage in the arteries that supply blood to the bottom walls of the heart. This type of STEMI can be caused by the blockage...

ECG showed sinus rhythm and ST–segment elevation in V1–V4 and Q waves in the anterior leads. Thus diagnosis of anterior STEMI was made and urgent coronary angiography was performed: left descending artery occlusion was treated with primary angioplasty. Laboratory tests pointed out high troponin ...
BackgroundThe presence of tricuspid regurgitation (TR) may affect prognosis in patients with mitral regurgitation (MR). 三尖瓣返流(TR)的存在可能影响二尖瓣返流(MR)患者的预后。 ObjectivesThis study sought to determine the impact of TR on outcomes in patients with heart failure and severe secondary...
The medical term for a widowmaker heart attack is an anterior ST-segment elevation myocardial infarction (STEMI). Each year, about 805,000 people in the United States have a heart attack, which happens when a portion of the heart does not receive enough oxygen-rich blood. How long does it...

Some anesthetics and antibiotics are known to cause this syndrome; however, Kounis Syndrome after the administration of Gadolinium contrast is not well described in the literature.Herein, we describe a case of acute anterior MI after the administration of a gadolinium-based contrast agent (...
STEMI was defined as continuous chest pain for at least 20 minutes, and new ST-segment elevation ≥0.1 mV in at least two contiguous leads, or new-onset left bundle branch block. Patients with Killip class > I on admission, heart failure, serum creatinine >250 µmol/L, ...
