Heart Rhythm
. 2022 May;
19(9):1491-1498.
PMID: 35525424
Background: Long QT syndrome (LQTS) is an inherited arrhythmia disorder characterized by ventricular repolarization abnormalities and a risk of sudden cardiac death. The electrophysiological components generating the high risk of...

15(12):e0243649.
PMID: 33315912
Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a severe inherited arrhythmic disease associated with a risk of syncope and sudden cardiac death (SCD). Aims: We aimed at identifying RYR2 P2328S...

Physiol Meas
. 2018 Dec;
39(11):115010.
PMID: 30500784
Objective: Our aim was to develop an automated detection method, for prescreening purposes, of early repolarization (ER) pattern with slur/notch configuration in electrocardiogram (ECG) signals using a waveform prototype-based feature...

Int J Cardiol
. 2018 Oct;
276:125-129.
PMID: 30293667
Background: Electrocardiographic (ECG) left ventricular hypertrophy (LVH) is an established risk factor for cardiovascular events. However, limited data is available on the prognostic values of different ECG LVH criteria specifically...

Ann Noninvasive Electrocardiol
. 2018 Jul;
23(6):e12582.
PMID: 29974557
Background: Hypertrophic cardiomyopathy (HCM) is characterized by ventricular repolarization abnormalities and risk of ventricular arrhythmias. Our aim was to study the association between the phenotype and ventricular repolarization dynamics in...

BMC Med Genet
. 2018 Apr;
19(1):56.
PMID: 29622001
Background: Long QT syndrome (LQTS) is an inherited cardiac disorder predisposing to sudden cardiac death (SCD). We studied factors affecting the clinical course of genetically confirmed patients, in particular those...

Circ Arrhythm Electrophysiol
. 2018 Feb;
11(2):e005762.
PMID: 29440187
Background: We developed a novel electrocardiographic marker, T-wave area dispersion (TW-Ad), which measures repolarization heterogeneity by assessing interlead T-wave areas during a single cardiac cycle and tested whether it can...

Int J Cardiol
. 2017 Oct;
250:139-145.
PMID: 29032884
Background: Ventricular fibrillation (VF) is a major cause of sudden cardiac death. In some cases clinical investigations fail to identify the underlying cause and the event is classified as idiopathic...

. 2017 Jul;
24(12):1386-1391.
PMID: 28697043
Objective: The aim of the study was to compare the effects of different hormone therapies on cardiac repolarization in recently postmenopausal women with and without hot flashes. Methods: We recruited...

Europace
. 2015 Dec;
18(10):1599-1607.
PMID: 26705554
Aims: Spontaneous Ca release leads to afterdepolarizations and triggered arrhythmia in catecholaminergic polymorphic ventricular tachycardia (CPVT). Irregular Ca release is hypothesized to manifest as slowed depolarization and irregular repolarization. Our...
