The Bainbridge reflex (aka, atrial reflex) occurs when the heart rate increases in response to a rise in atrial pressure. This is a compensatory mechanism since increased right atrial pressures ...

Men with PAH had a larger right heart size and worse survival than women, independent of body size and functional status, a ...

Women are more likely to have pulmonary arterial hypertension, but men tend to have worse outcomes and worse treatment responses.

As mitral stenosis progresses, increased left atrial pressure is required to maintain stroke volume. This pressure increase is generated primarily by the right heart and results in increased ...

"If the heart isn't relaxing, the filling pressure increases, which means the atrial pressure increases, and that can lead to hypertrophy and fibrosis of the atrium, both of which increase the ...

The approach works by creating a connection between the left and right atrial chambers using a short pulse of energy to cut tissue, reducing pressure buildup within the left atrium. The pivotal ...

Left-ventricular, right-ventricular and right-atrial size ... lung physiology restricted by morbid obesity or both can elevate atrial pressures and trigger ectopy and AF. Vagal stimulation of ...

There was no significant difference between CPR groups as regards systolic, mean, diastolic aortic and right atrial pressures, intracranial, cerebral perfusion (CPP), or myocardial perfusion (MPP ...
