Prognostic Value of the Global Left Ventricular Contractility Index in Patients with Severe Mitral Regurgitation and Preserved Left Ventricular Ejection Fraction

Journal of Cardiovascular Development and Disease
Introduction: Assessment of left ventricular (LV) systolic function is important in valvular heart disease. The global LV contractility index, dσ*/dtmax, is load-independent and has been reported to be associated with clinical outcomes in heart failure ...

Trifascicular block in patient with acute coronary syndrome

Universidad Médica Pinareña, 2020
Introduction: prolongation of the QRS complex due to complete and incomplete blockages of the left branch of the His bundle is an important predisposing factor for systolic heart failure.

Transcatheter heart valve selection and permanent pacemaker implantation in patients with pre-existent right bundle branch block [PDF]

, 2017
Background-Right bundle branch block is an established predictor for new conduction disturbances and need for a permanent pacemaker (PPM) after transcatheter aortic valve replacement.

ECG patterns of left anterior fascicular block and conduction impairment in ventricular myocardium: a whole-heart model-based simulation study [PDF]

, 2018
Left anterior fascicular block (LAFB) is a heart disease identifiable from an abnormal electrocardiogram (ECG). It has been reported that LAFB is associated with an increased risk of heart failure.

ON THE PHYSIOLOGY OF HEART-BLOCK IN MAMMALS, WITH ESPECIAL REFERENCE TO THE CAUSATION OF STOKES-ADAMS DISEASE

Journal of Experimental Medicine, 1905
The facts collected in the third part of this paper justify the following conclusions: (1) All of the cardinal symptoms of Stokes-Adams disease may be duplicated by heart-block resulting from a lesion in or near the auriculo-ventricular bundle of His ...

Third-degree heart block in thalassemia major: A case report [PDF]

, 2012
Background: First and second-degree heart blocks are partly common rhythm disorders in thalassemic patients but complete heart block is a very rare complication of iron overload cardiomyopathy.

In vivo dose measurement using TLDs and MOSFET dosimeters for cardiac radiosurgery. [PDF]

, 2012
In vivo measurements were made of the dose delivered to animal models in an effort to develop a method for treating cardiac arrhythmia using radiation. This treatment would replace RF energy (currently used to create cardiac scar) with ionizing radiation.

Prolonged Corrected QT Interval as an Early Electrocardiographic Marker of Cyclophosphamide‐Induced Cardiotoxicity in Pediatric Hematology and Oncology Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...

Right and left-sided infective endocarditis in an IV drug abuser

Journal of Community Hospital Internal Medicine Perspectives, 2020
Infective endocarditis (IE) involving multiple cardiac valves is uncommon and has more risk of complications. We present an interesting case of infective endocarditis involving both aortic and tricuspid valves, suspected based on clinical presentation ...
