Ventricular late potentials in familial amyloidotic polyneuropathy

Journal of Electrocardiology, 2006
We investigated the occurrence of ventricular late potentials (LPs) in patients with familial amyloidotic polyneuropathy (FAP) and the possible association with ventricular arrhythmia on Holter electrocardiography and echocardiographic data. Fifty-five patients and 94 healthy controls were studied. LP were found in 46% of the FAP patients older than 60

The Effects of Direct Current Countershock on Ventricular Late Potentials

PACE - Pacing and Clinical Electrophysiology, 1987
Signal averaging is a noninvasive method of recording ventricular late potentials. These late potentials are present in many patients with sustained ventricular tachycardia. Analysis of ventricular late potential characteristics may develop as a useful marker of antiarrhythmic drug efficacy.

Late Ventricular Potentials and QT Dispersion in Familial Dysautonomia

Pediatric Cardiology, 2009
Familial dysautonomia is a worldwide disorder characterized by maldevelopment and dysfunction of the autonomic and sensory systems. Despite major improvements in disease management in recent years, sudden death remains the cause of death in up to 43% of patients.

Late coronary angioplasty and ventricular late potentials

The American Journal of Cardiology, 1998
To assess the effect of successful late coronary angioplasty of an occluded infarct-related artery on the prevalence of ventricular late potentials, signal-averaged electrocardiograms were recorded in 123 consecutive patients surviving a first acute myocardial infarction (58 with and 65 without mechanical reperfusion of the occluded coronary artery ...

Late Potential Abolition in Ventricular Tachycardia Ablation

The American Journal of Cardiology, 2022
Ventricular tachycardia (VT) substrate-based ablation has become the gold standard treatment for patients with structural heart disease-related VT. VT is linked to re-entry in relation to myocardial scarring, with areas of conduction block (core scar) and of slow conduction (border zone).

Ventricular Late Potentials in Myotonic Dystrophy

Annals of Internal Medicine, 1991
To determine the prevalence of ventricular late potentials, as determined by signal-averaged electrocardiography, in patients with myotonic dystrophy.Cross sectional, with blinded analysis of all electrocardiographic data.Outpatient departments of a Veterans Affairs medical center and a tertiary care private hospital.Twenty-four patients with myotonic ...

Analyzing late ventricular potentials

IEEE Engineering in Medicine and Biology Magazine, 1996
The authors show the mechanism of high frequency attenuation introduced by signal averaging and how it can be avoided by applying a high resolution alignment approach, coupled with optimal filtering of the reference lead. Several authors suggest that ventricular late potentials are due to high frequency components caused by abnormal ventricular ...

[Late potentials and ventricular arrhythmia].

Annales de cardiologie et d'angeiologie, 1986
When electrodes are placed at the surface of the thorax, high-amplification electrocardiography (HA-ECG) combined with signal summation as a function of time provides a non-invasive method for detecting electric potentials occurring after the QRS complex of the clinical electrocardiogram. These potentials are called late, and can probably be likened to

Late potentials and their correlation with ventricular structure in patients with ventricular arrhythmias

Pacing and Clinical Electrophysiology, 2017
AbstractIntroductionThe presence of late potentials (LP) may indicate a predisposition to ventricular arrhythmias and sudden cardiac death. We investigated the association between presence of LP and structural cardiac anomalies assessed by magnetic resonance (CMR) in patients presenting with ventricular arrhythmias.MethodsWe included 42 patients ...

Late potentials and ventricular arrhythmias in arrhythmogenic right ventricular cardiomyopathy

The American Journal of Cardiology, 1999
We studied 38 patients (mean age 32 +/- 14 years) with arrhythmogenic right ventricular cardiomyopathy (ARVC) to evaluate the clinical significance of histologic features on endomyocardial biopsy specimens as related to signal-averaged electrocardiography (SAECG), spontaneous ventricular arrhythmias, and hemodynamic features. Fifteen patients presented
