Distinctive Left Ventricular Activations Associated With ECG Pattern in Heart Failure Patients.
BACKGROUND In contrast to patients with left bundle branch block (LBBB), heart failure patients with narrow QRS and nonspecific intraventricular conduction delay (NICD) display a relatively limited response to cardiac resynchronization therapy. We sought to compare left ventricular (LV) activation patterns in heart failure patients with narrow QRS and NICD to patients with LBBB using high-densi...
متن کاملVariable left ventricular activation pattern in patients with heart failure and left bundle branch block.
OBJECTIVE To determine the left ventricular (LV) activation pattern in patients with chronic heart failure and left bundle branch block (LBBB) on ECG. DESIGN Prospective study. SETTING Tertiary cardiology referral centre in Hong Kong. PATIENTS Seven patients with LV ejection fraction < 35% and typical LBBB on ECG with QRS duration > or = 130 ms were recruited. Five of them had non-ischaem...
متن کاملLeft ventricular mass in patients with heart failure.
OBJECTIVE To assess left ventricular mass in patients with heart failure and its correlations with other clinical variables and prognosis. METHODS The study comprised 587 patients aged from 13.8 years to 68.9 years, 461 (78.5%) being males and 126 (21.5%) females. Left ventricular mass was estimated by using M-mode echocardiography and was indexed by height. RESULTS The left ventricular mas...
متن کاملLeft Ventricular Pacing In Patients With Congestive Heart Failure
Cardiac resynchronisation therapy (CRT) using biventricular (BIV) pacing has proved its effectiveness to correct myocardial asynchrony and improve clinical status of patients with severe congestive heart failure (CHF) and widened QRS. Despite a different effect on left ventricular electrical dispersion, left univentricular (LV) pacing is able to achieve the same mechanical synchronisation as BI...
متن کاملChronic Left Ventricular Heart Failure
The effect of the vasodilator prazosin vs placebo on exercise duration until marked dyspnea, and on left ventricular function measured by echocardiography, was evaluated in a double-blind, randomized study in 24 patients with chronic left ventricular failure despite digitalis and diuretic therapy. Compared with the double-blind placebo, prazosin reduced resting systolic and diastolic blood pres...
