Study Notes
Cardiac Rhythms and Management
- An increase of 10 bpm or more in resting heart rate is linked to a higher risk of sudden cardiac death, atrial fibrillation, heart failure, coronary artery disease (CAD), stroke, and cardiovascular disease.
Sinus Bradycardia
- Characterized by a heart rate of less than 60 bpm, normal P wave positioned before QRS, PR interval between 0.12 and 0.20 seconds.
- 1:1 ratio of P waves to QRS complexes.
- Management based on symptoms: symptomatic patients may require atropine, transcutaneous pacing, or catecholamines.
- Nurse actions include patient assessment for symptoms like fatigue and light-headedness. For asymptomatic cases, monitor ECG and vital signs.
Sinus Tachycardia
- Defined by a heart rate greater than 100 bpm with a regular rhythm and normal P waves (which may be obscured in T waves).
- Management involves treating underlying causes, with symptomatic patients potentially requiring synchronized cardioversion or adenosine administration.
- Important nursing actions include assessing patient status and checking for factors such as fever or dehydration.
Ventricular Dysrhythmias
- Premature Ventricular Complex (PVC): Early impulse from the ventricle with abnormal QRS morphology, visible P waves depend on PVC timing, PR interval less than 0.12 seconds.
- Ventricular Tachycardia (VTACH), Ventricular Fibrillation (VFIB), PEA, and Asystole are critical pulseless rhythms that necessitate immediate CPR.
Heart Sounds and Clinical Assessment
- Third Heart Sound (S3) is indicative of heart failure, heard during rapid ventricular filling.
- Fourth Heart Sound (S4) relates to hypertensive heart disease, occurring during atrial contraction.
- Other sounds include opening snaps (associated with AV valve malfunction) and systolic clicks (from stenosis of semilunar valves).
- Murmurs caused by turbulent blood flow can result from narrowed or malfunctioning valves.
- A friction rub is a harsh sound linked to pericarditis and can mimic murmurs.
Cardiopulmonary Resuscitation (CPR)
- Effective CPR consists of a compression to breath ratio of 30:2.
- The process prioritizes assessing the patient's responsiveness and circulation, followed by calling for assistance.
- Essential to provide blood flow to vital organs until circulation is restored.
Myocardial Infarction
- Acute Coronary Syndrome leads to myocardial death due to ischemia.
- STEMI shows characteristic ECG changes; NSTEMI presents elevated cardiac biomarkers without notable ECG changes.
- Treatment begins with oxygen, followed by nitroglycerin, morphine, and aspirin (with contraindications for low blood pressure and viagra use).
- Patient education includes lifestyle modifications and monitoring for cardiac symptoms.
Coronary Artery Disease (CAD) Risk Factors
- Modifiable: hyperlipidemia, tobacco use, hypertension, diabetes, and obesity.
- Nonmodifiable: family history, age, gender, race.
- Post-Operative Care after CABG focuses on ensuring adequate heart function and monitoring for complications.
Heart Failure
- Key diagnostic test: B-type natriuretic peptide (BNP).
- Right heart failure presents with edema and distended neck veins; left heart failure affects lung function, causing dyspnea.
- Risk factors include myocardial infarction, aging, and valve abnormalities.
- Education emphasizes a low-sodium diet and daily weight monitoring.
Atherosclerosis and Peripheral Vascular Disease (PAD)
- Atherosclerosis involves plaque build-up influenced by both modifiable (smoking, diabetes) and nonmodifiable (age, genetics) risk factors.
- PAD often presents as intermittent claudication and is characterized by reduced blood flow to limbs.
- Patient education on foot hygiene is crucial; complications include ulcers and gangrene.
Hypertension
- New definitions categorize hypertension over 130/80 mmHg; complication risks include heart attack and kidney disease.
- Primary hypertension has no identifiable cause; secondary hypertension stems from specific conditions.
- Evidence suggests lifestyle changes and dietary modifications are essential for management.
- Medications include thiazide diuretics, ACE inhibitors, and calcium channel blockers; patient education is crucial for adherence and monitoring.
Hypertensive Crisis
- Defined by severe elevations in blood pressure (>180/100 mmHg).
- Emergency treatment requires immediate intervention to decrease mean arterial pressure by 20-25% with IV vasodilators.
- Urgency requires careful monitoring without evidence of immediate organ damage.
