    Study Notes

    Nursing Interventions for Dysrhythmias

    • Evaluate patient response to dysrhythmias; document findings.
    • Encourage patient to report chest pain promptly.
    • Assess characteristics of chest pain: location, intensity, duration, radiation, and factors influencing pain.
    • Check peripheral circulation: assess pulses, edema, capillary refill, color, and extremity temperature.
    • Administer antidysrhythmic treatments as per unit policy (e.g., medications, cardioversion, defibrillation).
    • Monitor and document the patient's reactions to antidysrhythmic medications.
    • Track relevant lab values such as cardiac enzymes and electrolyte levels.
    • Observe the patient's activity tolerance; plan exercise and rest to prevent fatigue.
    • Watch for respiratory issues: shortness of breath, rapid or labored breathing.
    • Encourage stress-relief practices and offer pastoral/spiritual support as needed.

    Sinus Bradycardia Symptoms and Interventions

    • Symptoms include syncope, dizziness, weakness, confusion, hypotension, diaphoresis, shortness of breath, and chest pain.
    • Identify and address the underlying cause if the patient is stable.
    • Administer IV atropine when the cause is uncertain; increase intravascular volume with IV fluids.
    • Provide oxygen if oxygen saturation falls below 94% or if the patient experiences shortness of breath.
    • Discontinue medications potentially causing bradycardia.
    • Glucagon may be administered in suspected beta-blocker overdose cases to increase heart rate and blood pressure.
    • Prepare for temporary pacing if heart rate remains low; consider permanent pacemaker if normal rhythm isn’t restored.

    Overview of Heart Failure (HF)

    • HF is a clinical syndrome characterized by fluid overload and inadequate tissue perfusion.
    • Results from cardiac disorders impeding ventricular function, where the heart insufficiently generates cardiac output.
    • Can involve systolic dysfunction (impaired contraction) or diastolic dysfunction (impaired filling).
    • Chronic and progressive nature; may be reversible under certain conditions, managed with lifestyle changes and medications.

    Types of Heart Failure

    • Systolic Heart Failure:
      • Characterized by reduced ejection fraction (EF) and impaired contraction.
    • Diastolic Heart Failure:
      • Known as HF with preserved EF; stiff heart muscle and difficulty filling.
    • Use echocardiograms to assess EF; normal EF is 55%-65%.

    Causes of Heart Failure

    • Key etiological factors include coronary artery disease (CAD), hypertension, cardiomyopathy, valvular disorders, renal dysfunction, atrial fibrillation, diabetes, and atherosclerosis.
    • CAD and hypertension increase cardiac workload and lead to hypertrophy or dilation, worsening heart function.

    Left-Sided Heart Failure

    • Known as congestive heart failure; results in fluid accumulation in the lungs due to left ventricle dysfunction.
    • Clinical manifestations: dyspnea (often orthopnea), cough (initially dry, may progress), pulmonary crackles, low oxygen saturation, and S3 gallop sound.
    • Decreased cardiac output causes renal and gastrointestinal perfusion decline, leading to complications like oliguria and altered digestion.

    Right-Sided Heart Failure

    • Results in fluid accumulation in the peripheral tissues; congestion and edema predominate.
    • Symptoms include jugular venous distension, dependent edema, hepatomegaly, ascites, weight gain, and generalized weakness.

    Management Considerations for Heart Failure

    • Monitor fluid status: lung sounds, daily weights, adherence to low sodium diets.
    • Positioning strategies: elevate head of bed, use extra pillows, or recline to alleviate pressure.
    • Provide anxiety control and support effective health management.
    • Watch for complications: pulmonary edema, kidney injury, dysrhythmias related to diuretic use.

    Mitral Valve Prolapse

    • Occurs when mitral valve leaflets enlarge and prolapse into the left atrium during systole; common in females and often asymptomatic.
    • Symptoms may include fatigue, chest pain, shortness of breath, syncope, palpitations, and a late systolic murmur.
    • Management includes dietary restrictions, avoiding stimulants, and possibly surgical interventions.

    Chronic Obstructive Pulmonary Disease (COPD)

    • Symptoms include dyspnea, productive cough, wheezing, and clubbing of fingers, often leading to hypoxia and cyanosis.
    • Divided into emphysema (characterized by overdistention of alveoli) and chronic bronchitis (marked by excessive mucus production).
    • Key risk factors include smoking, exposure to pollutants, and genetic factors.

    Pathophysiology of COPD

    • Emphysema involves obstruction due to trapped air and loss of elastic recoil, leading to difficulty exhaling.
    • Chronic bronchitis features inflammation and mucus production, causing airway obstruction and hypoxia, commonly leading to right heart failure.
