VECTOR ELECTROCARDIOGRAPHY IN THE DIAGNOSTICS OF FOCAL CHANGES IN THE MYOCARDIUM

open access: yesРоссийский кардиологический журнал, 2015
Acute coronary disease diagnostics improvement is a worldwide priority. The introduction of a promising method of study of the electromotive force of the heart with the use of information technologies, allows us to diagnose acute myocardial infarction ...

Mechanical dyssynchrony as a selection criterion for cardiac resynchronization therapy: Design of the AMEND‐CRT trial

open access: yesESC Heart Failure, Volume 11, Issue 6, Page 4390-4399, December 2024.
Abstract Aims One third of patients do not improve after cardiac resynchronization therapy (CRT). Septal flash (SF) and apical rocking (ApRock) are deformation patterns observed on echocardiography in most patients eligible for CRT. These markers of mechanical dyssynchrony have been associated to improved outcome after CRT in observational studies and ...

EFFECT OF RITUXIMAB ON CARDIAC ELECTROPHYSIOLOGICAL PARAMETERS IN PATIENTS WITH RHEUMATOID ARTHRITIS

open access: yesНаучно-практическая ревматология, 2018
Rheumatoid arthritis (RA) is an autoimmune rheumatic disease characterized by damage not only to the joints, but also to the viscera, including the heart. The cardiovascular risk in patients with RA is 1.5 times higher than that in the general population.

An Investigative Redesign of the ECG and EMG Signal Conditioning Circuits for Two-fault Tolerance and Circuit Improvement [PDF]

open access: yes, 1991
An investigation was undertaken to make the elctrocardiography (ECG) and the electromyography (EMG) signal conditioning circuits two-fault tolerant and to update the circuitry.

On the derivation of the spatial QRS-T angle from Mason-Likar leads I, II, V2 and V5 [PDF]

open access: yes, 2015
The spatial QRS-T angle (SA) has been identified as a marker for changes in the ventricular depolarization and repolarization sequence. The determination of the SA requires vectorcardiographic (VCG) data.

Changes in QRS Area and QRS Duration After Cardiac Resynchronization Therapy Predict Cardiac Mortality, Heart Failure Hospitalizations, and Ventricular Arrhythmias

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Predicting clinical outcomes after cardiac resynchronization therapy (CRT) and its optimization remain a challenge. We sought to determine whether pre‐ and postimplantation QRS area (QRSarea) predict clinical outcomes after CRT.

Is there a utility for QRS dispersion in clinical practice? [PDF]

open access: yes, 2017
Prognostic markers derived from standard ECG have always been seductive. Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular arrhythmias, sudden ...

Feasibility of transthoracic echocardiographic guidance for multicatheter electrophysiological mapping studies in horses

open access: yesJournal of Veterinary Internal Medicine, Volume 38, Issue 5, Page 2686-2697, September/October 2024.
Abstract Background Improved characterization of arrhythmias is based on minimally invasive catheterizations. However, these catheterizations have been poorly explored in horses because apart from 3‐dimensional (3D) mapping systems, continuous guidance of the catheter's position with adequate detail is difficult using current imaging modalities ...

Noninvasive assessment of reperfusion and reocclusion after thrombolysis in acute myocardial infarction. [PDF]

open access: yes, 1993
The clinical significance of ST-segment changes and of the time course of appearance in serum of different cardiac proteins has been reviewed for the diagnosis of coronary reperfusion and reocclusion after thrombolysis. In particular, the value of serial
