A Case with no Hemodynamic Benefit from Right Ventricular Anodal Capture during Biventricular Pacing

Journal of Arrhythmia, 2007
This case report describes a patient with a biventricular pacing system in whom right ventricular anodal capture had no hemodynamic benefit. While controlling the ventricular output, three morphologies of the paced QRS complex were obtained: right ...

Quality of Life in Patients with Implantable Cardioverter Defibrillators [PDF]

, 2006
Background: The implantable cardioverter defibrillator (ICD) is a life saving device for individuals with life threatening ventricular arrhythmias. There is no doubt that it is a cost effective therapy in various congenital and acquired arrhythmogenic ...

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

Long-term Effect of Dual-chamber Pacing on Pressure Gradient at Left Ventricular Outflow Tract in Hypertrophic Obstructive Cardiomyopathy

Journal of Arrhythmia, 2011
A 60-year-old man with hypertrophic obstructive cardiomyopathy (HOCM) was implanted dual-chamber ICD for the purpose of both the left ventricular outflow tract (LVOT) gradient reduction by ventricular pacing and the primary prevention of ventricular ...

Automatic Mode Switching in Atrial Fibrillation [PDF]

, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Pacing failure caused by automatic pacing threshold adjustment system

Journal of Arrhythmia, 2017
Ventricular capture management is an automatic pacing threshold adjustment algorithm that automatically measures pacing threshold through detection of the evoked response after a pacing stimulus. Although it is principally designed to save device battery

Osborn Waves: History and Significance [PDF]

, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...
