Hace 4 días · In the normal heart, the TDI diastolic pattern at the mitral annulus mirrors that of transmitral blood-flow Doppler where the both E wave and e′ velocity are high, due to the predominance of rapid early diastolic filling, while the A wave and a′ are comparatively low.
Hace 4 días · The normal heart has four chambers: a left and right atrium which are located on top of the heart, and a left and right ventricle which are located below the atria. The ventricles act as the main pump of the heart.

Hace 4 días · The ABCs of Heart Disease is a system for diagnosing cardiac disease in adults by asking certain questions in a set fashion, the answers to which are certain fundamental observations made from the frontal chest x-ray alone.
Hace 4 días · Echocardiography is widely used to evaluate left ventricular (LV) diastolic function in patients suspected of heart failure. For patients in sinus rhythm, a combination of several echocardiographic parameters can differentiate between normal and elevated LV filling pressure with good accuracy.
Hace 1 día · A normal respiratory rate for adults is between 12 to 18 breaths per minute. Normal respiratory rates for children depend on how old they are. For example, babies and toddlers take more breaths per minute than older kids and teens.
Hace 5 días · While heart rate is the number of heart beats over a period of time, typically a minute, heart rate variability (HRV) refers to ways to quantify the variability between heartbeats: even if we count 60 beats in a minute, they do not happen exactly every second.
