44
Afterload: Definition: The resistance the ventricles must overcome to eject blood during systole. Relationship to SV: Increased afterload .... Decreased afterload....
Increased Afterload: (e.g., in hypertension or aortic stenosis): Makes it harder for the heart to pump blood, reducing stroke volume. Decreased afterload: Reduces the resistance, allowing the ventricles to eject blood more easily, increasing stroke volume.

Preload, Contractility, Afterload Describe using the balloon analogy
Preload: Refers to the stretchyness of the ballon in relation to the amount of air (blood) that was in it at the End of Filling (Diastole). Sterling's law states Preload the more stretch in the ventricles in Diastole the great the contraction during systole (Ejection) Contractility: Ballons inherit ability to stretch - IS IT DEPENDENT ON PRE / AFTERLOAD Afterload: The knot in the end of the ballon closing it. Afterload is the force systole must overcome to enter into the aorta

Echocardiogram (Echo) OR Electrocardiogram (ECG/EKG) Purpose Assesses heart structure and function. Records the electrical activity of the heart. Focus Provides images of the heart's chambers, valves, walls, and blood flow. Monitors heart rhythms and detects electrical abnormalities. Procedure Uses ultrasound to create detailed images of the heart. Uses electrodes attached to the skin to measure electrical signals. Common Uses - Evaluate heart function (e.g., ejection fraction) - Detect valve diseases, clots, or structural abnormalities - Assess blood flow in heart and vessels - Diagnose arrhythmias - Detect ischemia, heart attack, or conduction disorders - Monitor heart rhythm over time Imaging Produces real-time images of the heart (ultrasound). Does not produce images; outputs a graph of electrical activity. Invasiveness Non-invasive (or minimally invasive with transesophageal echo). Non-invasive. Duration 15–45 minutes. 5–10 minutes. Outcome Visual and functional assessment of the heart. Detection of electrical or rhythm abnormalities. Conditions Diagnosed - Heart failure - Valve diseases - Congenital defects - -Arrhythmias - Myocardial infarction - Heart block

Diuretics (e.g., Furosemide): Reduce fluid overload, preload, and pulmonary congestion. Monitor electrolytes and renal function. Vasodilators (e.g., Nitroglycerin): Lower preload and afterload, improve cardiac output. Watch for hypotension. Inotropes (e.g., Dobutamine): Enhance contractility and cardiac output in severe cases. Monitor for arrhythmias. Anticoagulants (e.g., Heparin): Prevent clot formation. Beta-Blockers (e.g., Metoprolol): Reduce heart rate and oxygen demand if stable; avoid in shock. ACE Inhibitors/ARBs (e.g., Lisinopril): Decrease afterload if stable; avoid in kidney injury or hyperkalemia. Nursing Tips: Ensure stability, monitor vitals and fluid status, and educate the patient on pre-procedure care.
