Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundIvabradine selectively inhibits the pacemaker current of the sinoatrial node, slowing heart rate. Few studies have examined the effects of ivabradine on the mechanical properties of the heart after reperfused myocardial infarction (MI ...

Left ventricular systolic and diastolic dyssynchrony in asymptomatic hypertensive patients
, 2009 BACKGROUND: Diastolic and systolic dyssynchrony are common in patients with heart failure. However, the presence of dyssynchrony in asymptomatic patients with hypertension who are susceptible to the development of heart failure is not well understood ...

Clinical utility of speckle-tracking echocardiography in cardiac resynchronisation therapy
Echo Research and Practice, 2016 Cardiac resynchronisation therapy (CRT) can profoundly improve outcome in selected patients with heart failure; however, response is difficult to predict and can be absent in up to one in three patients. There has been a substantial amount of interest in

Pacing and Clinical Electrophysiology, Volume 49, Issue 10, Page 1595-1603, October 2026.ABSTRACT Background Implantable cardioverter‐defibrillator (ICD) therapy relies on reliable right ventricular leads for pacing, sensing, and defibrillation. The INVICTA DF4 lead is an active‐fixation, quadripolar design intended to optimize implant workflow and long‐term safety and performance. Methods APOLLO was a prospective, multicenter, single‐arm,

Potentially beneficial patient-ventilator dyssynchrony: is it possible?
Patient-ventilator dyssynchronies are entities commonly observed during mechanical ventilation. Their persistence can be injurious to lung tissue and the diaphragm.

An Epidemic of Dyssynchrony But What Does It Mean? [PDF]
, 2008 Cardiac resynchronization therapy (CRT) is used to treat a subset of heart failure patients with discoordinate wall motion. Defining appropriate patients is important, and, although electrical delay (wide QRS) is commonly used, recent data show that ...

Health Science Reports, Volume 9, Issue 9, September 2026.ABSTRACT Background and Aims Systolic anterior motion (SAM) represents the displacement of the anterior mitral leaflet during ventricular systole toward the interventricular septum, causing an obstruction of the outflow tract. Most of the published data regards the primary SAM that is associated with hypertrophic cardiomyopathy. This review was focused

Why Dyssynchrony Matters in Heart Failure?
, 2019 Cardiac resynchronization therapy (CRT) is an electrical therapy to resolve an electrical problem. Any method to predict CRT response must specifically reflect the electrical substrate.

Health Science Reports, Volume 9, Issue 9, September 2026.ABSTRACT Background and Aims Anecdotal concerns persist regarding the safety of cold and warm water ingestion and their impact on cardiac rhythms. This study aimed to investigate the acute effects of water temperature on QRS amplitude, duration, and axis in healthy individuals using electrocardiography (ECG).
