Abstract:
A 60-year-old woman was admitted with chief complaints of dyspnea for the previous 3 weeks. Transthoracic echocardiography (TTE) showed the amount of pericardial effusion and signs of cardiac tamponade. However, a tumor was not detected by TTE in any view. Multidetector computed tomography (MDCT) showed that the tumor protruded into the right atrium, invading to the outside of the heart. Transesophageal echocardiography (TEE) also showed the mobile tumor in the right atrium. In conclusion, this report may demonstrate that MDCT and TEE are required as complementary methods in the detection of cardiac tumors.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...

Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
