INVESTIGATIONS IN CARDIOVASCULAR MEDICINE Flashcards
What are the types of cardiovascular investigations?
- ELECTROCARDIOGRAPHY
- ECHOCARDIOGRAPHY
- AMBULATORY BLOOD PRESSURE MONITOR(ABPM)
- HOLTER
- STRESS ELECTROCARDIOGRAPHY
- CHEST X RAY
- ANGIOGRAPHY
- CARDIAC ENZYMES
What is ECG and it’s indications?
An ECG studies the electrical activity of the heart
It is indicated for:
* Chest pain:To determine the cause of chest pain
* Heart rhythm:To identify irregular heartbeats, such as palpitations, fluttering, or pounding
* Shortness of breath:To evaluate shortness of breath, which may be a sign of a heart problem
* Dizziness:To evaluate dizziness, which may be a sign of a heart problem
* Fainting:To evaluate fainting, which may be a sign of a heart problem
* Fatigue:To evaluate severe tiredness, which may be a sign of a heart problem
* Heart health:To assess the overall health of the heart before surgery or other procedures
* Pacemaker:To see how well an implanted pacemaker is working
* Heart medications:To see how well certain heart medications are working
* Baseline:To get a baseline tracing of the heart’s function during a physical exam
* Family history:To evaluate a strong history of heart disease in the family
An ECG is often the first test done to determine whether a person has heart disease.
What is an echocardiogram?
An echocardiogram, or echo, is a noninvasive imaging test that can be used to diagnose a variety of heart conditions.
Indication of an echocardiogram
- Suspected heart failure
- Hypertension and suspected left ventricular hypertrophy
- Suspected cardiac mass
- Pulmonary disease
- Pre-cardioversion in patients with atrial fibrillation
- Palpitations and pre-syncope/syncope
- Suspected pericardial disease
- Established cardiomyopathies
- Aortopathy
- Elective non-cardiac surgery
- Chest pain
- Shortness of breath
- Lightheadedness or dizziness
- Fainting
- Unusual fatigue
- A strong heart murmur or a change in a heart murmur
- Pain or numbness in the extremities
What are some abnormal findings in an Echocardiogram?
- Heart valves:Abnormal valves can be damaged, regurgitate (leak), or narrow (stenosis).
- Heart muscle:The heart’s muscles may be weakened or damaged, or there may be impaired wall motion.
- Blood flow:Blood flow may be abnormal or turbulent, which could indicate a vascular or intracardiac abnormality.
- Heart size:The heart or ventricles may be enlarged.
- Pericardium:The pericardium, the membrane around the heart, may be swollen or irritated (pericarditis), or there may be excess fluid around the heart (pericardial effusion)
- Endocarditis:The inner lining of the heart’s valves and chambers may be dangerously inflamed.
- Blood clots:Blood clots may be present in the heart chambers or be the result of a stroke or TIA.
- Congenital heart disease:The heart may have a congenital defect.
- Atrial fibrillation:The heartbeat may be irregular and rapid.
- Cardiovascular disease:The heart muscles may be damaged due to high blood pressure or high cholesterol.
What does an ECG with no P wave indicate?
Atrial fibrillation
What does an ECG with a tall T wave indicate?
Myocardial infarction
What does an ECG with a prolonged QT wave indicate?
Calcium abnormalities
What are types of Heart Failure?
HF with preserved ejection fraction
HF with reduced ejection fraction
Marginally reduced ejection fracture
What is Ejection Fraction?
Ejection fraction is measured as a percentage of the total amount of blood in your heart that is pumped out with each heartbeat.
