Diastolic and systolic right ventricular dysfunction precedes left ventricular dysfunction in VVI-paced patients

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex

BACKGROUND Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic fashion. METHODS Patients with symptomatic bradycardia and ACC-AHA Class I indication for permanent pacemaker implantation (PPI) were implanted a s...

echocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction

background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy   (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction   is associated with lvh and inappropriate lvm. methods: one hundred   and twenty five uncomplicated hypertensi...

Intrinsic Myocardial Dysfunction During Development of Left Ventricular Pressure-Overload Hypertrophy in Conscious Sheep Systolic Dysfunction Precedes Diastolic Dysfunction

Background. Patients with aortic stenosis have a period of compensated left ventricular hypertrophy but may eventually develop congestive heart failure. Previous experimental studies showed either normal myocardial contractility in mild short-term pressure overload or myocardial dysfunction with severe pressure overload. Transition from compensated left ventricular hypertrophy to myocardial dys...

Isolated right ventricular systolic dysfunction in scleroderma.

Scleroderma is a multi-systemic disease of the connective tissue, characterised by inflammatory alterations, occlusive microvascular lesions, and diverse forms of cutaneous and parenchymatous fibrosis. Although its pathogenesis is unsettled, various immune mechanisms have been implicated. Arthralgias, changes in oesophageal motility, spider veins, pulmonary fibrosis, and pulmonary arterial hype...
