WebApr 12, 2024 · ObjectivesThis study sought to assess the value of myocardial deformation using strain echocardiography in patients with mitral valve prolapse (MVP) and severe ventricular arrhythmia and to evaluate its impact on rhythmic risk stratification.BackgroundMVP is a common valvular affection with an overly benign … WebQRS fragmentation can also reflect electrical dyssynchrony. We hypothesized that quantification of abnormal QRS peaks (QRSp) would predict CRT response. Methods Forty-seven CRT patients (left ventricular ejection fraction = 23±7%) were prospectively studied. Digital 12-lead ECGs were recorded during native rhythm at baseline and 6…

WebBax and colleagues defined dyssynchrony as the maximum difference in TPSV between the basal anterior, inferior, septal, or lateral ventricular walls. 15 A value of 65ms was used as a cut-off with a sensitivity and specificity of 80% for predicting an improvement in NYHA classification and ≥25% increase in six-minute walking distance with CRT. WebDyssynchrony and Risk of Ventricular Arrhythmias. LV dyssynchrony, defined as nonuniform timing of peak myocardial shortening, may have several underlying … bridal shops in towson
