Objectives: To determine whether the biplane area-length method can be used for the evaluation of left atrial volumes and ejection fraction with cardiovascular magnetic resonance imaging (CMR) by TrueFISP in normal subjects and patients with atrial fibrillation. Background: Atrial fibrillation is the most common arrhythmia in elderly patients. Left atrial(More)
INTRODUCTION Cardiovascular magnetic resonance (CMR) allows very accurate, but time-consuming, volume assessment by the short-axis slice summation technique. The single and biplane methods of volume assessment are used less, partly because FLASH cine imaging provides poor blood-myocardium contrast in long-axis views. TrueFISP gives excellent(More)
1. Desensitization of muscarinic K+ current (IK(ACh)) was studied in cultured atrial myocytes from guinea-pig hearts using whole-cell voltage clamp. 2. Three different types of desensitization could be identified. A fast component which upon rapid superfusion with ACh resulted in a partial relaxation of IK(ACh) within a few seconds to a plateau which was(More)
