Sgarbossa's criteria are a set of electrocardiographic findings generally used to identify myocardial infarction (also called acute myocardial infarction or a "heart attack") in the presence of a left bundle branch block (LBBB) or a ventricular paced rhythm. [1] Myocardial infarction (MI) is often difficult to detect when LBBB is present on ECG ...
Coronary ischemia and coronary artery disease are contributors to the development of heart failure over time. [10] Diagnosis of coronary ischemia is achieved by an attaining a medical history and physical examination in addition to other tests such as electrocardiography (ECG), stress testing, and coronary angiography. [11]
It is often a sign of myocardial ischemia, of which coronary insufficiency is a major cause. Other ischemic heart diseases causing ST depression include: Subendocardial ischemia [3] or even infarction. [4] Subendocardial means non full thickness ischemia. In contrast, ST elevation is transmural (or full thickness) ischemia; Non Q-wave ...
The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...
Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
Iridocorneal endothelial (ICE) syndromes are a spectrum of diseases characterized by slowly progressive abnormalities of the corneal endothelium and features including corneal edema, iris distortion, and secondary angle-closure glaucoma. [1] [2] [3] ICE syndromes are predominantly unilateral and nonhereditary.
The T wave should be deflected opposite the terminal deflection of the QRS complex. This is known as appropriate T wave discordance with bundle branch block. A concordant T wave may suggest ischemia or myocardial infarction. [citation needed]
IMA measures ischemia in the blood vessels and thus returns results in minutes rather than traditional markers of necrosis that take hours. ACB test has low specificity therefore generating high number of false positives and must be used in conjunction with typical acute approaches such as ECG and physical exam. Additional studies are required.
