What is the most accurate way to diagnose cardiac tamponade?
GaleEncyofMedicine
When cardiac tamponade is suspected, accurate diagnosis can be life-saving. The most accurate way to identify this condition is by using a test called an echocardiogram.

What injury would most likely cause obstructive shock?
Cardiac tamponade
What are the most common conditions to be treated by pericardiocentesis?
Cardiac tamponade and pericarditis are two primary complications that require intervention with pericardiocentesis.
What is the shape of the Cardiac muscle?
Your cardiac muscles is your heart. Make a fist with one of your hands. This is the closest and most accurate shape and size of YOUR heart.
How does cardiac tamponade cause cyanotic?
Cardiac tamponade is a condition caused by rapid buildup of fluid (usually blood, but some conditions cause other fluids to collect) in the pericardial sac (see question below for definition of pericardium). Small amounts of fluid or fluid that accumulates over a long period of time does not cause problems, but when the fluid volume becomes too high or it accumulates rapidly, the pressure within the pericardium rises and may eventually lead to compression of the cardiac chambers, restricting filling and emptying. This is most prominent in the right sided chambers, specifically the right atrium and ventricle. Restriction of filling results in a decrease in cardiac output and eventually hypotension, shock, and (if uncorrected) death. This is a not uncommon cause of PEA (pulseless electrical activity) in traumatically injured patients. Signs and symptoms of cardiac tamponade include the classic signs of hypotension/shock, jugular venous distention and muffled heart sounds. Together, these signs bear the eponym "Beck's triad." Not all patients with cardiac tamponade will have all of these signs, however. Clinical suspicion in the appropriate setting still plays a major role in diagnosis. Other signs include those caused by these three core signs - altered mental status, weak or absent peripheral pulses, cyanosis, respiratory distress or failure, diaphoresis, tachycardia as the heart tries to compensate for a decreased output and hypotension, decreased urine output, and others. Diagnosis of cardiac tamponade is done either on appropriate clinical suspicion in appropriate patients and physical exam or by ultrasound at the bedside. Rapid bedside ultrasound will reveal a large pericardial effusion with compression of the R heart structures, particularly in diastole. This is diagnostic of cardiac tamponade. Treatment includes pericardiocentesis at bedside, either blindly or ultrasound guided or emergent pericardial window in the OR. In traumatic cases, particularly penetrating trauma, the cause is an atrial or ventricular injury or proximal aortic injury and these treatments will cause only temporary improvement with worsening again upon reaccumulation of blood. In this case, the treatment is thoracotomy and primary repair of the cardiac injury. Emergency thoractomy may be performed in the emergency department as a temporizing measure to give the patient time to make it to the OR when vital signs are lost, but overall mortality is high.

Can psychics predict pregnancy?
Psychics are the most accurate way do diagnose a pregnancy. Except, you know, a doctor, midwife, or even a $1 at home pee test.
What are the most accurate methods of heart disease diagnosis?
Doctors can conduct all sorts of tests to diagnosis heart disease. They typically do a blood test, an echocardiography, and a cardiac catherization.
What cells make up the myocardium?
Most of the myocardium is composed of cardiac myocytes.
What is the least accurate way to diagnose an MI?
CKMB and Troponin marker tests are used for diagnosis of a myocardial infarction. (heart attack). Keeping in mind that a positive blood marker is but one of three criteria used. For a diagnosis of an MI two of three criteria must be met. 1. positive elevation of the st segment in an ECG, 2. Symptoms consistent with myocardial infarction and/or 3. a positive troponin or CKMB. CKMB measures creatine kinase. This is a by product in blood from muscle damage. As the heart is a muscle this can be indicative of cardiac damage. This test is less reliable than a troponin test as results can be altered by other muscle damage. CKMB is not cardiac specific. Troponin is now the most commonly used test for cardiac damage. It is cardiac specific.
How would you describe the cells of the cardiac muscle?

Vein that drains most of anterior ventricles?
small cardiac vein
Does cardiac muscle have a relation to the heart?
Yes, its what most of the heart is made out of.
How can you revive a patient from cardiac arrest?
cardiopulmonary resuscitation is the most effective treatment for cardiac arrest.
