Diagnosis of Rejection by Analyzing Ventricular Late Potentials in Heart Transplant Patients [PDF]

Arquivos Brasileiros de Cardiologia, 2016
Background: Heart transplant rejection originates slow and fragmented conduction. Signal-averaged ECG (SAECG) is a stratification method in the risk of rejection. Objective: To develop a risk score for rejection, using SAECG variables.

Aortic valve artifact during ventricular tachycardia originating from the outflow tract [PDF]

Indian Pacing and Electrophysiology Journal
A 61-year-old male with dilated cardiomyopathy underwent electrophysiological study for incessant ventricular tachycardia (VT). Although early and late diastolic potentials were recorded in the aortic sinus during VT, electrograms obtained during the ...

Incessant ventricular tachycardia from a surviving Purkinje network years after myocardial infarction: A case report [PDF]

Indian Pacing and Electrophysiology Journal
Ventricular tachycardia (VT) in the setting of chronic myocardial infarction (MI) is overwhelmingly attributed to macro-reentry. We report an extremely rare case of late-onset, incessant monomorphic VT driven by abnormal Purkinje automaticity.

Evaluation of the efficacy of signal-averaged electrocardiogram testing in the cardiac assessment of beta-thalassemia major patients

BMC Cardiovascular Disorders, 2022
Background More than 70% of thalassemia’s major mortality is due to the cardiac complications of this syndrome, mostly consequent to myocardial Iron overload; therefore, evaluation of such complications is of utmost importance.

Conduction properties of the preferential pathway in a patient with idiopathic outflow ventricular arrhythmia

Indian Pacing and Electrophysiology Journal, 2022
Ventricular arrhythmias (VA) originating from the outflow tract often conduct via a preferential pathway into a distant breakout site in the ventricular myocardium.

Defining the substrate for ventricular tachycardia ablation: The impact of rhythm at the time of mapping

Indian Pacing and Electrophysiology Journal, 2020
Background: Voltage mapping is critical to define substrate during ablation. In ventricular tachycardia, abnormal potentials may be targets. However, wavefront of activation could impact local signal characteristics.

Analysis of the Prevalence of Ventricular Late Potentials in the Late Phase of Myocardial Infarction Based on the Site of Infarction

Arquivos Brasileiros de Cardiologia, 2002
OBJECTIVE: The initial site of myocardial infarction (MI) may influence the prevalence of ventricular late potentials (VLP), high-frequency signals, due to the time course of ventricular activation.
