Concealed WPW Syndrome with Longitudinal Dissociation in the His Bundle Exhibiting Five Different Electrocardiographic Waveforms During Tachycardia

open access: yesJournal of Arrhythmia, 2005
We examined a patient with concealed WPW syndrome who exhibited five different electrocardiographic waveforms during tachycardia. With the intracardiac electrogram, all tachycardia were artrioventricular reciprocating tachycardia with retrograde ...

Epidemiological research of radioactive springs (Misasa Hot Springs) on circulatory systems. II. Incidences of abnormal ECG findings and hypertension (A preliminary report) [PDF]

open access: yes, 1966
Misasa Hot Springs water contains 4.81-1169.2×10(-10) curie per liter of radon and its temperature ranges from 53.0℃ to 76.0℃. The authors examined one group of 265 residents who are living over 1 year at Misasa Hot Springs and another control group of ...

Atrial Septal Defect Associated With Right Bundle Branch Block Masking Brugada Syndrome

open access: yesJACC: Case Reports, 2023
A type 1 Brugada electrocardiogram pattern may be masked by typical right bundle branch block aspect. We present 2 cases (male patients, aged 18 and 22 years) of associated ostium secundum atrial septal defect with a right bundle branch block aspect and ...

Classification of Arrhythmia by Using Deep Learning with 2-D ECG Spectral Image Representation

open access: yes, 2020
The electrocardiogram (ECG) is one of the most extensively employed signals used in the diagnosis and prediction of cardiovascular diseases (CVDs). The ECG signals can capture the heart's rhythmic irregularities, commonly known as arrhythmias.

Ventricular arrhythmias in young competitive athletes: Prevalence, determinants, and underlying substrate [PDF]

open access: yes, 2018
Whether ventricular arrhythmias (VAs) represent a feature of the adaptive changes of the athlete's heart remains elusive. We aimed to assess the prevalence, determinants, and underlying substrates of VAs in young competitive athletes.Background--Whether ...

Programming Cardiac Resynchronization Therapy for Electrical Synchrony: Reaching Beyond Left Bundle Branch Block and Left Ventricular Activation Delay

open access: yesJournal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2018
Background QRS narrowing following cardiac resynchronization therapy with biventricular (BiV) or left ventricular (LV) pacing is likely affected by patient‐specific conduction characteristics (PR, qLV, LV‐paced propagation interval), making a universal ...

Defining Left Bundle Branch Block Patterns in Cardiac Resynchronisation Therapy: A Return to His Bundle Recordings

open access: yesArrhythmia & Electrophysiology Review, 2019
Left bundle branch block (LBBB) is associated with improved outcome after cardiac resynchronisation therapy (CRT). One historical presumption of LBBB has been that the underlying pathophysiology involved diffuse disease throughout the distal conduction ...
