What are the normal heart sounds and their characteristics?
S1 ‘lubb’ marks the beginning of systole, caused by closure of mitral and tricuspid valves. S2 ‘dubb’ marks the beginning of diastole, caused by closure of aortic and pulmonary valves.
S1 is louder at the apex; S2 is louder at the base, higher pitched & shorter.
What is S2 physiologic splitting?
S2 consists of aortic (A2) and pulmonic (P2) valve closure. On inspiration, A2 is heard first, followed by P2. On expiration, the two sounds are close together and detected as a single S2.
Usually heard in younger patients.
What are abnormal heart sounds?
Abnormal heart sounds include S3, S4, systolic clicks, pathologic splitting, rubs, or gallops.
Pathologic splitting can be wide, fixed, or paradoxical.
What is S3 and its significance?
S3 is a physiologic sound frequently heard in children and young adults, occurring early in diastole, dull and low in pitch. Pathologic S3 indicates high left ventricular filling pressures.
Causes include decreased myocardial contractility and heart failure.
What is S4 and its common causes?
S4 is an ‘atrial sound’ that occurs just before S2, dull and low in pitch, commonly due to ventricular hypertrophy or fibrosis.
Causes include HTN heart disease and aortic stenosis.
What are normal peripheral vascular findings?
Normal findings include strong and equal pulses (2+) in major arteries, brisk capillary refill (< 3 seconds), lack of edema, normal hair distribution, and an ankle-brachial index (ABI) between 0.9 – 1.4.
Equal limb circumference and symmetrical warmth are also indicators.
What are abnormal peripheral vascular findings?
Abnormal findings include weak/absent pulses, bounding pulses, delayed capillary refill, pitting edema, calf asymmetry, unilateral swelling, and bilateral edema.
Visible venous collaterals may indicate upper extremity DVT.
Define heart failure.
Heart failure is the heart’s inability to pump enough blood to meet the body’s needs, also known as congestive heart failure.
Hallmark features include edema, shortness of breath, and testing with ECG, chest X-ray, and echocardiogram.
What is angina pectoris?
Angina pectoris is chest pain or discomfort due to decreased oxygen to the heart muscle, characterized by substernal pressure that can radiate to the shoulder, arm, neck, or jaw.
Testing includes ECG and stress tests.
What is mitral valve prolapse (MVP)?
MVP is a defect of the mitral valve causing improper closure and backflow of blood into the left atrium, characterized by a mid-systolic click and late systolic murmur.
Echocardiogram is the primary test.
What is Raynaud’s phenomenon?
Raynaud’s phenomenon is temporary narrowing of blood vessels in extremities causing color changes in response to stress or cold.
Symptoms include numbness and tingling.
What is deep vein thrombosis (DVT)?
DVT is blood clot formation in a deep vein, characterized by swelling, discoloration, pain, and warmth in the affected extremity.
Testing includes ultrasound and D-dimer labs.
What are the symptoms of arterial insufficiency?
Symptoms include intermittent claudication, cold or pale legs, weak pulses, and skin changes such as thin, shiny skin and ulcers.
Complications can lead to gangrene or amputation.
What characterizes venous insufficiency?
Venous insufficiency is a condition where veins cannot return blood effectively to the heart, leading to symptoms like swelling, heaviness, and aching in the legs.
It can cause brownish pigmentation and venous ulcers.
Differentiate between venous ulcers and arterial ulcers.
Venous ulcers: occur above the ankle, are shallow with irregular borders. Arterial ulcers: occur on toes or heels, are deep with well-defined borders.
Venous ulcers are due to poor venous return; arterial ulcers are due to poor arterial circulation.
Where are heart murmurs best heard?
Heart murmurs are best heard in the four valve areas: Aortic area, Pulmonary area, Tricuspid area, Mitral area.
Specific intercostal spaces correspond to each area.
What are physiologic murmurs?
Physiologic murmurs are innocent, functional murmurs common in children, usually normal sounds made as blood pumps through the heart.
They may get louder when a child is excited or ill.
What are pathologic murmurs?
Pathologic murmurs are associated with structural heart disease, often require medical intervention, and can indicate heart problems.
They are typically loud and may have a blowing or squeaky sound.
What are some methods of assessing heart murmurs?
Assessment methods include maneuvers like handgrip, squatting, Valsalva, and standing abruptly.
These maneuvers can change the intensity of different murmurs.
What is the grading system for heart murmurs?
Murmurs are graded from I to VI. Systolic murmurs occur between S1 and S2, while diastolic murmurs occur between S2 and S1.
Systolic murmurs always end in VI; diastolic always in IV.
What are the screening recommendations for alcohol abuse?
Screen all adults for unhealthy alcohol use, assess family history, social problems, and use the CAGE questionnaire.
Look for signs of liver disease during physical examination.
What questionnaire is used to screen for alcohol misuse?
CAGE questionnaire
The CAGE questionnaire is a widely used tool for identifying potential alcohol problems.
What are signs of liver disease to assess during a physical examination?
Signs include:
* Hepatosplenomegaly
* Ascites
* Caput medusae
* Jaundice
* Spider angiomas
* Palmar erythema
* Dupuytren contractures
* Gynecomastia
These signs may indicate underlying liver dysfunction or disease.
What is the recommended alcohol consumption limit for women?
Up to one drink/day
This recommendation is based on guidelines from the U.S. Office of Disease Prevention and Health Promotion.
