Cardio Flashcards

1
Q

What is cardiac tamponade?

A

Compression of the heart caused by fluid collecting in the pericardial sac

It results in a weaker pump and less cardiac output.

Q

Why is cardiac tamponade considered a medical emergency?

A

It can lead to a dramatic drop in blood pressure that can be fatal

The heart cannot fill and pump effectively due to compression.

Q

What are the acute causes of cardiac tamponade?

A

Trauma (stabbing or motor vehicle accident)

Acute causes involve sudden injury to the heart or pericardium.

Q

What is a chronic cause of cardiac tamponade?

A

Pericarditis

This is inflammation of the pericardium that can lead to fluid accumulation.

Big Jugular Vein Distension, Extreme Low BP, Can’t hear heart sounds

These signs are indicative of cardiac tamponade.

Q

What is pulse paradoxus?

A

Systolic drop of 10 mmHg

Example: A drop from 120/80 to 110/80 is a sign of cardiac tamponade.

Q

What are the characteristics of ECG findings in cardiac tamponade?

A

QRS complexes are short and uneven height

These changes can indicate the presence of cardiac tamponade.

Q

What is the first step in the treatment of cardiac tamponade?

A

Pericardiocentesis

This procedure involves draining the fluid from the pericardial sac.

Q

What is involved in the procedure of pericardiocentesis?

A

Cardiac monitor, catheter attached to drainage system, assess drainage

Monitoring and assessment are critical for patient safety during the procedure.

Clients present with distended heart muscles

Q

What is the main feature of Hypertrophic Cardiomyopathy?

Q

What does obstructive mean in the context of cardiomyopathy?

Q

What do all forms of cardiomyopathy lead to?

A

Less cardiac output, resulting in less oxygen-rich blood to the body

This is a critical factor in heart failure

Q

What is the only cause of Hypertrophic Cardiomyopathy?

A

Genetics only

Other types may have multiple causes

17
Q

List common signs and symptoms of low oxygen.

A
  • Restlessness
  • Agitation
  • Altered level of consciousness
  • Syncope
  • Dizziness
  • Fatigue

These symptoms are indicative of hypoxia

18
Q

What are signs of left-sided heart failure?

A
  • Lung fluid

This can lead to pulmonary congestion

19
Q

What are signs of right-sided heart failure?

A
  • Edema
  • Ascites
  • Jugular vein distention (JVD)

This reflects systemic congestion

20
Q

What is a significant physical finding in Dilated Cardiomyopathy?

A

53 murmur and cardiomegaly

Cardiomegaly refers to an enlarged heart

21
Q

What is the typical presentation of Hypertrophic Cardiomyopathy?

A

Typically asymptomatic until heavy exercise, can lead to sudden death

This is especially concerning in children

22
Q

What are the main classes of medications used in cardiomyopathy?

A
  • ACE Inhibitors (e.g., Lisinopril)
  • Beta Blockers (e.g., Atenolol)
  • Calcium Channel Blockers (e.g., Diltiazem, Verapamil)
  • Digoxin
  • Diuretics (e.g., Furosemide, HCTZ)

Each class has specific roles in managing heart failure

23
Q

When should Digoxin be held?

A
  • Apical pulse < 60
  • Potassium (K+) < 3.5
  • Digoxin level > 2.0

These conditions indicate risk for digoxin toxicity

24
Q

What are common side effects of Digoxin toxicity?

A
  • Vision changes
  • Nausea/Vomiting
  • Fatigue
  • Dizziness

Monitoring for these symptoms is crucial

25
Q

What are the lab tests used to assess heart function?

A
  • Chest X-ray
  • MRI
  • Echocardiogram
  • Angiography
  • BNP levels

Each test provides different insights into heart health

26
Q

What is considered a normal ejection fraction (EF)?

A

55-70%

An EF of 40% or less indicates heart failure

27
Q

What BNP levels indicate heart failure?

A
  • 100 or less: Normal
  • 101-299: Mild elevation
  • 300+: Mild heart failure
  • 600+: Moderate heart failure
  • 900+: Severe heart failure

BNP is a marker for heart failure severity

28
Q

What does the DRESS acronym stand for in patient education?

A
  • Diet (low sodium & low fat)
  • Rest periods
  • Exercise
  • Stop smoking & alcohol
  • Stress reduction

These lifestyle changes are crucial for managing heart conditions
