ECG changes seen in left ventricular hypertrophy (LVH) and right ventricular hypertrophy (RVH). Unable to load your collection due to an error
Objective: To determine if there is a significant difference in the predictive abilities of left ventricular hypertrophy (LVH) detected by ECG-LVH versus LVH ascertained by cardiac MRI-LVH in a model similar to the Framingham Heart Failure Risk Score (FHFRS). The two most common pressure overload states are systemic hypertension and aortic stenosis.
Such hypertrophy is usually the response to a chronic pressure or volume load. However, intrinsicoid deflection (time of ascent of the R wave) may be lengthened with hypertrophy. He has a passion for ECG interpretation and medical education.does the LVH with strain pattern carry any pathologic significance?

The two most common pressure overload states are … DISCUSSION The key finding of this analysis is that, while ECG-LVH was predictive of the risk of incident HF, substituting MRI-LVH for ECG-LVH improved the predictive ability of a model similar to the FHFRS.
1949. This revised view challenges cardiologists and electrocardiologists to explore the interrelationships between electrical, biochemical, and mechanical alterations of myocardial remodeling seen with heart disease, to advance our understanding of this process and its effects, including the evolution of the ECG changes known as "LVH".
doi: 10.1016/j.jelectrocard.2017.06.006. Left ventricular hypertrophy is enlargement and thickening (hypertrophy) of the walls of your heart's main pumping chamber (left ventricle).Left ventricular hypertrophy can develop in response to some factor — such as high blood pressure or a heart condition — that causes the left ventricle to work harder. While LVH itself is not a disease, it is usually a marker for disease involving the heart.Causes of increased afterload that can cause LVH include Two dimensional echocardiography can produce images of the left ventricle.
It should be noted that there are newer, more complicated, indexes which are utilized in modern ECG machines but the sensitivity and specificity is only negligible better than the old indexes.Join our newsletter and get our free ECG Pocket Guide!Clinical electrocardiography and ECG interpretationCardiac electrophysiology: action potential, automaticity and vectorsThe ECG leads: electrodes, limb leads, chest (precordial) leads, 12-Lead ECG (EKG)The Cabrera format of the 12-lead ECG & lead –aVR instead of aVRECG interpretation: Characteristics of the normal ECG (P-wave, QRS complex, ST segment, T-wave)How to interpret the ECG / EKG: A systematic approachMechanisms of cardiac arrhythmias: from automaticity to re-entry (reentry)Aberrant ventricular conduction (aberrancy, aberration)Premature ventricular contractions (premature ventricular complex, premature ventricular beats)Premature atrial contraction (premature atrial beat / complex): ECG & clinical implicationsSinus rhythm: physiology, ECG criteria & clinical implicationsSinus bradycardia: definitions, ECG, causes and managementChronotropic incompetence (inability to increase heart rate)Sinoatrial arrest & sinoatrial pause (sinus pause / arrest)Sinoatrial block (SA block): ECG criteria, causes and clinical featuresSinus node dysfunction (SND) and sick sinus syndrome (SSS)Sinus tachycardia & Inappropriate sinus tachycardiaAtrial fibrillation: ECG, classification, causes, risk factors & managementAtrial flutter: classification, causes, ECG diagnosis & managementEctopic atrial rhythm (EAT), atrial tachycardia (AT) & multifocal atrial tachycardia (MAT)Atrioventricular nodal reentry tachycardia (AVNRT): ECG features & managementPre-excitation, Atrioventricular Reentrant (Reentry) Tachycardia (AVRT), Wolff-Parkinson-White (WPW syndrome)Junctional rhythm (escape rhythm) and junctional tachycardiaVentricular rhythm and accelerated ventricular rhythm (idioventricular rhythm)Ventricular tachycardia (VT): ECG criteria, causes, classification, treatment (management)Longt QT interval, long QT syndrome (LQTS) & torsades de pointesVentricular fibrillation, pulseless electrical activity and sudden cardiac arrestPacemaker mediated tachycardia (PMT): ECG and managementDiagnosis and management of narrow and wide complex tachycardiaIntroduction to Coronary Artery Disease (Ischemic Heart Disease) & Use of ECGClassification of Acute Coronary Syndromes (ACS) & Acute Myocardial Infarction (AMI)Clinical application of ECG in chest pain & acute myocardial infarctionDiagnostic Criteria for Acute Myocardial Infarction: Cardiac troponins, ECG & SymptomsMyocardial Ischemia & infarction: Reactions, ECG Changes & SymptomsThe left ventricle in myocardial ischemia and infarctionFactors that modify the natural course in acute myocardial infarction (AMI)ECG in myocardial ischemia: ischemic changes in the ST segment & T-waveST segment depression in myocardial ischemia and differential diagnosesST segment elevation in acute myocardial ischemia and differential diagnosesST elevation myocardial infarction (STEMI) without ST elevations on 12-lead ECGT-waves in ischemia: hyperacute, inverted (negative), Wellen's sign & de Winter's signECG signs of myocardial infarction: pathological Q-waves & pathological R-wavesSupraventricular and intraventricular conduction defects in myocardial ischemia and infarctionECG localization of myocardial infarction / ischemia and coronary artery occlusion (culprit)Approach to patients with chest pain: differential diagnoses, management & ECGNSTEMI (Non ST Elevation Myocardial Infarction) & Unstable Angina: Diagnosis, Criteria, ECG, ManagementSTEMI (ST Elevation Myocardial Infarction): diagnosis, criteria, ECG & managementSecond-degree AV block: Mobitz type 1 (Wenckebach) & Mobitz type 2 blockThird-degree AV block (3rd degree AV block, AV block 3, AV block III)Management and treatment of AV block (atrioventricular blocks)Intraventricular conduction delay: bundle branch blocks & fascicular blocksRight bundle branch block (RBBB): ECG, criteria, definitions, causes & treatmentLeft bundle branch block (LBBB): ECG criteria, causes, managementLeft bundle branch block (LBBB) in acute myocardial infarction: the Sgarbossa criteriaFascicular block (hemiblock): left anterior & left posterior fascicular block on ECGNonspecific intraventricular conduction delay (defect)Atrial and ventricular enlargement: hypertrophy and dilatation on ECGECG in left ventricular hypertrophy (LVH): criteria and implicationsRight ventricular hypertrophy (RVH): ECG criteria & clinical characteristicsBiventricular hypertrophy ECG and clinical characteristicsLeft atrial enlargement (P mitrale) & right atrial enlargement (P pulmonale) on ECGDigoxin -
