Because of the heart’s orientation and “suspension” in the chest, sleeping on the left side can cause subtle changes in the heart’s position, says Leonard Ganz, M.D., cardiologist and ...

The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure. Normally, blood pressure drops less precipitously than 10 mmHg during inhalation. Pulsus paradoxus is a sign that is indicative of several conditions, most commonly pericardial effusion .
