Alternating and gradually changing narrow QRS complex tachycardia in a patient with heart failure: What is the mechanism?

Annals of Noninvasive Electrocardiology, 2021
A 23‐year‐old woman with palpitations for 9 years was referred for catheter ablation. ECG showed an irregular narrow complex tachycardia with alternating and gradually changing QRS morphologies after alternating and changing RR intervals, with a clear ...

Prognostic role of high‐sensitivity cardiac troponin T in patients with cardiac sarcoidosis: insights from ILLUMINATE‐CS

ESC Heart Failure, Volume 12, Issue 2, Page 869-878, April 2025.
Abstract Aims The prognostic role of high‐sensitivity cardiac troponin T (hs‐cTnT) as a biomarker in patients with cardiac sarcoidosis (CS) has yet to be fully determined, especially when compared with B‐type natriuretic peptide (BNP). Methods and Results In this post‐hoc analysis of the ILLUMINATE‐CS (ILLUstration of the Management and prognosIs of ...

Partial Unroofed Coronary Sinus Associated With Upper Septal Ventricular Tachycardia and Atrioventricular Nodal Reentrant Tachycardia

Indian Pacing and Electrophysiology Journal, 2015
A 58 year old gentleman with complaints of palpitations and documented tachycardia was found to have a dilated right atrium, right ventricle and coronary sinus, which were due to partial unroofed coronary sinus without a left superior vena cava.

Ablation of idiopathic fascicular ventricular tachycardia [PDF]

Orvosi Hetilap, 2009
Az idiopathiás fascicularis kamrai tachycardia fontos és nem nagyon ritka szívritmuszavar specifikus EKG-jelekkel és terápiás lehetőségekkel. A kamrai tachycardia EKG-képe relatíve keskeny QRS-morfológiát mutat a jobb-Tawara-szár-blokk morfológiájával. A QRS-tengelyállás attól függ, hogy melyik fasciculus része a reentry körnek. Baltengely-deviáció van

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

ESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).

Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia

Indian Pacing and Electrophysiology Journal, 2005
Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle branch and inferior axis morphology.

“From Surface to Substrate: Advancing VT Ablation Strategies for Deep Arrhythmic Substrates”—A Review of Emerging Techniques in Intramural Lesion Formation

Reviews in Cardiovascular Medicine
Intramural ventricular tachycardia represents a formidable frontier in catheter ablation, where the arrhythmogenic substrate resides deep within the myocardial wall, often beyond the reach of conventional energy delivery.

Transendocardial injection of expanded autologous CD34+ cells after myocardial infarction: Design of the EXCELLENT trial

ESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.
Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.
