Figure Lengend Snippet: Right ventricular enlargement in Dsg2 mt/wt mice after endurance swim training is alleviated by preload-reducing therapy. ( A – D ) Representative echocardiographic images of the short-axis view during diastole after endurance swim training of Dsg2 WT ( A ) and Dsg2 mt/wt ( B ) mice treated with placebo and Dsg2 WT ( C ) and Dsg2 mt/wt ( D ) mice with preload-reducing treatment therapy. The blue dotted line surrounds the area measured of the right ventricle in the short-axis view. ( A’ – D’ ) MRI showing prospectively triggered cardiac Cine magnetic resonance images acquired at 9.4 T (groups and protocols as in ( A – D )). ( E ) Bar graphs showing increased left ventricular mass/body weight (LVmass/BW) index after endurance swim training without (placebo) and with preload-reducing therapy (* p < 0.05). Augmentation of the index provides evidence that the training was effective. ( F ) Bar graphs representing the measured diastolic right ventricular (RV) area in the short axis view during echocardiography before and after training, without (placebo) and with preload reduction therapy in Dsg2 WT and Dsg2 mt/wt mice (* p < 0.05). After training, Dsg2 mt/wt mice showed an increased RV short axis area. ( G ) Bar graphs showing calculated diastolic RV volume before and after training, without (placebo) and with preload reduction therapy in Dsg2 WT and Dsg2 mt/wt mice (* p < 0.05). After training, RV volume was enlarged in trained and placebo-treated Dsg2 mt/wt mice compared with before training and with trained and untreated Dsg2 WT mice. ( H ) Contractility of the RV shown by the fractional area change (FAC) measured in the short axis view (sav) before and after training, with placebo and with therapy in Dsg2 WT and Dsg2 mt/wt mice (* p < 0.05). After training, FAC RV sav was reduced in trained Dsg2 mt/wt mice.

Article Title: Beta-adrenergic contributions to emotion and physiology during an acute psychosocial stressor

doi: 10.1097/PSY.0000000000001009

Figure Lengend Snippet: Study timeline illustrating repeated measure timing of self-reported emotions, continuous electrocardiogram (ECG) and impedance cardiography (ICG), and salivary cortisol and alpha-amylase measures. Note that, although not depicted here, appraisals were measured alongside emotion, but only at the TSST Prep and Post-TSST timepoints.

Article Snippet: To assess sympathetic and parasympathetic activity, we collected continuous electrocardiography (ECG) and impedance cardiography (ICG) at a sampling rate of 1000 Hz using Mindware Technologies (Gahanna, OH, USA).
