Does this meet STEMI criteria, or is it just Left Ventricular Hypertrophy (LVH)? What is LVH? When the left ventricle is constantly pumping against increased resistance (chronically high blood pressure, aortic stenosis), .Echocardiographic analysis showed a significant difference in ejection fraction, indexed LVH, and mitral inflow E-wave and A-wave ratio (Table 3). ECG analysis of the test cohort showed that the S waves in leads V 3 and V 4 were good . Left ventricular hypertrophy, or LVH, is a term for a heart’s left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork .
Left ventricular hypertrophy (LVH) is when the heart’s main pumping chamber, the left ventricle, becomes thicker and less able to pump blood efficiently. It usually develops because of.

S-T Segment. The ST segment is the flat, isoelectric section of the ECG between the end of the S wave (the J point) and the beginning of the T wave.. The ST Segment represents the interval between ventricular . HCM is an inherited cardiac disorder and is the number one cause of sudden cardiac death in young people. Genetic mutations cause left ventricular hypertrophy in the absence of any inciting stimulus. Both the degree and distribution of LVH is variable, and can range from mild (13-15mm) to extreme myocardial thickening (30mm+).

This is an example of Pseudo-Wellens syndrome due to left ventricular hypertrophy. ECG Review. LVH by voltage criteria (SV1 + RV6 > 35mm) The pattern of inverted and biphasic T waves is different to Wellens syndrome, affecting multiple leads (i.e. any lead with a tall R wave) rather than V2-3
Low voltage QRS: QRS amplitude < 5mm in limb leads Mechanisms. Low voltage is produced by: The “damping” effect of increased layers of fluid, fat or air between the heart and the recording electrode

ECG Motion Artefacts, shiver, hypothermia, CPR, precordial thump: ECG Diagnosis: Multifocal Atrial Tachycardia (MAT) Multifocal Atrial Tachycardia, Chaotic atrial tachycardia: ECG Diagnosis: Myocardial Ischaemia. Myocardial . The most common cause of a dominant R wave in aVR is incorrect limb lead placement, with reversal of the left and right arm electrodes. This produces a similar pattern to dextrocardia in the limb leads but with normal R-wave progression in the chest leads. Left ventricular hypertrophy may produce a similar appearance to LBBB, with QRS widening and ST depression / T-wave inversion in the lateral leads. Related Topics. Left bundle branch block LBBB; Right Bundle Branch Block RBBB; Left anterior fascicular block LAFB; Left posterior fascicular block LPFB; Myocardial injury with necrosis where a condition other than CAD contributes to an imbalance between myocardial oxygen supply and/or demand, e.g. coronary endothelial dysfunction, coronary artery spasm, coronary embolism, tachy-/brady-arrhythmias, anemia, respiratory failure, hypotension, and hypertension with or without LVH; Type 3

LVH, ace of spades, left ventricular hypertrophy, apical hypertrophic cardiomyopathy (HCM), apical HCM ECG Quiz Library 128 hypertension, inferior occlusion myocardial infarction (OMI), 1st degree AV block, ST depression Increased QRS voltage is often taken to infer the presence of left ventricular hypertrophy. However, high left ventricular voltage (HLVV) may be a normal finding in patients less than 40-45 years of age, particularly slim or athletic individuals. There are multiple “voltage criteria” for left ventricular hypertrophy. Wellens Syndrome. Wellens syndrome is a pattern of inverted or biphasic T waves in V2-3 (in patients presenting with/following ischaemic sounding chest pain) that is highly specific for critical stenosis of the left anterior descending artery.. There are two patterns of T-wave abnormality in Wellens syndrome:. Type A = Biphasic T waves with the initial deflection .
Smith-Modified Sgarbossa Criteria. As discussed in this article by Stephen Smith, the Smith modified Sgarbossa criteria for Occlusion Myocardial Infarction (OMI) in LBBB have been created to improve diagnostic accuracy. The most important change is the modification of the rule for excessive discordance.. The use of a 5 mm cutoff for excessive discordance was . J point in a) normal; b) c) J point elevation; d) J point depression; e) with J wave (Osborn wave) Note: The letter J on the ECG defines 2 totally different and unrelated events.The J point is a point in time marking the end of the QRS and the onset of the ST segment present on all ECG’s; the J wave is a much less common long slow deflection of uncertain origin originally .
Clinical Pearls Other important ECG patterns to be aware of: Anterior-inferior STEMI due to occlusion of a “wraparound” LAD.This presents with simultaneous ST elevation in the precordial and inferior leads, due to occlusion of a variant (“type III”) LAD that wraps around the cardiac apex to supply both the anterior and inferior walls of the left ventricle Post cardiac arrest. Marked ST elevation in aVR which is a reciprocal change to widespread ST depression – even in the presence of a right bundle branch block, ST depression in V2 and V3 is excessively discordant; This ECG was taken 5 minutes post return of spontaneous circulation (ROSC) in a patient who suffered a VF arrest. RWPT in wide QRS complex tachycardia. R-wave peak time (RWPT) may be useful in differentiating ventricular tachycardia (VT) from supraventricular tachycardia (SVT) in patients with wide QRS complex tachycardia:. RWPT duration is measured in lead II from the onset of QRS depolarization until the first change of polarity (with both positive or negative .

Left ventricular hypertrophy, or LVH, is a term for a heart’s left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle. In response to this pressure overload, the inner walls of the heart may respond by getting thicker.
