Body composition is a key determinant of health. Many methods, including bioelectrical impedance analysis (BIA), are available to estimate body composition; however the validity of such methods varies greatly. The aim of this cross sectional study was to investigate the accuracy of the Tanita MC-180MA BIA machine in the quantification of fat mass through comparison with Magnetic Resonance Imaging (MRI)....

Ventricular premature complexes (VPCs) are a frequent finding, even in patients without heart disease. There is an age-dependent increase in prevalence, and might be present in many structural heart diseases. VPCs are present in about 1% of routine ECGs, in up to 80% of 24-hour Holters and might be transiently present in 80 to 90% of patients after an acute myocardial infarction (AMI). The mechanisms by which they are generated include reentry, enhanced automaticity and triggered activity....
