Many diseases of the right side of the heart are associated with electrocardiographic abnormalities. Electrocardiography is neither a sensitive nor specific tool for diagnosing conditions such as right atrial enlargement, right ventricular hypertrophy, or pulmonary hypertension. However, an awareness of the electrocardiographic abnormalities associated with these conditions may support the pati...

We highlight a significant problem that needs to be considered and addressed when performing functional near-infrared spectroscopy (fNIRS) studies, namely the possibility of inadvertently measuring fNIRS hemodynamic responses that are not due to neurovascular coupling. These can be misinterpreted as brain activity, i.e., "false positives" (errors caused by wrongly assigning a detected hemodynam...
