Detection of left ventricular diffuse fibrosis with quantitative T1 mapping in patients with paroxysmal atrial fibrillation
Background Background: Quantitation of T1 relaxation times (T1 time) is a novel non-invasive CMR technique which can detect both interstitial and replacement fibrosis. T1 changes consistent with interstitial fibrosis have been described in conditions associated with left ventricular (LV) remodeling and systolic dysfunction, including chronic mitral regurgitation and aortic stenosis. Atrial fibr...
متن کاملParoxysmal Ventricular Fibrillation with Spontaneous Reversion to Sinus Rhythm.
Ventricular fibrillation is the cause of sudden circulatory arrest in about 30 per cent of cases (Jude, Kouwenhoven, and Knickerbocker, 1961). Paroxysms of ventricular fibrillation frequently account for Stokes-Adams attacks in patients with complete heart block (Parkinson, Papp, and Evans, 1941; Portal et al., 1962). Though Stokes-Adams attacks occur not infrequently in patients with sinus rhy...
متن کاملElectromechanical Abnormalities in Patients with Paroxysmal Atrial Fibrillation
Background: The loss of effective atrial contraction is associated with an increased thromboembolic risk. Aim: To study the electromechanical coupling of the atria in patients with paroxysmal atrial fibrillation (time of occurrence of the episodes <48 hours) using pulsed-wave tissue Doppler imaging. Materials and methods: The study included 51 patients (26 men, 25 women; mean age 59.84±1.60 yea...
متن کاملDispersion of atrial repolarization in patients with paroxysmal atrial fibrillation.
UNLABELLED To study the role of the dispersion of atrial repolarization (DAR) in the genesis of atrial fibrillation (AF), monophasic action potentials (MAP) were recorded simultaneously from a catheter at the high lateral right atrium (HLRA) and a catheter moving around the high, middle and low lateral right atrium (RA) the high, anterior and posterior septal RA and the RA appendage in 15 patie...
متن کاملSignal-averaged P wave in patients with paroxysmal atrial fibrillation.
The theoretical and experimental rational of atrial signal-averaged ECG in patients with AF is delay in the intra-atrial and interatrial conduction. Similar to the ventricular signal-averaged ECG, the atrial signal-averaged ECG is an averaging of a high number of consecutive P waves that match the template created earlier P wave triggering is preferred over QRS triggering because of more accura...
