T wave represents - Study guides, Class notes & Summaries

Electrocardiogram (ECG) correct answer: Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) correct answer: Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? correct answer: Only monitors Straight line when machine is turned on but not connected to the patient correct answer: Isoelectric = no current ...

ST Elevation Myocardial Infarction (STEMI) ~ Myocardial infarction which results from a thrombus permanently lodging in the vessel which results in the progression of the myocardial infarction to include the entire thickness of the ventricular wall Cardiac Troponins ~ Very reliable way to diagnose MI -Can be detected in 2-4 hours after onset of pain and should be monitored -They peak at 24 hours and disappear within 7-10 days Myocardial ischemia ~ This is marked by T wave inversion ...

Which of the EKG findings is most likely indicative of Acute Myocardial Infarction (AMI) in a patient presenting with acute chest pain? A. Wide and bizarre QRS complexes in the EKG B. ST segment changes (STEMI or NSTEMI) in the EKG C. A saw-toothed pattern in the EKG saw-toothed pattern in the EKG D. Flat line in the EKG - Answer- B. ST segment changes (STEMI or NSTEMI) in the EKG To determine whether there is a delay in impulse conduction through the atria, the nurse will measure the len...

what is the most accurate method for acquiring heart rate? Correct Answer: 1500 method As an impulse moves toward a positive electrode it produces what type of deflection? Correct Answer: upward on ECG papers horizontal measurements are used to determine what? Correct Answer: heart rate the initiation of the impulse in the SA Node and its movement through the atria produce? Correct Answer: P-wave repolarization of the ventricles is represented by the? Correct Answer: T-wave a...

Basic Cardiac Rhythm Interpretation Advanced Exam Review Update A+ 1 / 22 P Wave Atrial Depolarization stim￾ulated by the firing of the SA node. Evaluate: consistent ap￾pearance and 1:1 relation￾ship with QRS complex. If not identical some, or all, may be atrial, but not SA node, in origin. IF >1 P-wave precedes QRS a heart block may be present. Basic Cardiac Rhythm Interpretation Advanced Exam Review Update A+ 2 / 22 PR Interval Impulse traveling time from the atriu...

etiology of aneurysms - arteriosclerosis HTN smoking/obesity bacterial infections congenital defects Trauma Marfan's syndrome (connective tissue disorder) what other defect can cause systolic murmurs? - ventricular septal defect (heard on the left sternal border) relievers for Unstable angina? what do labs look like? ECG? - Nitroglycerin. Troponin negative. ST depression or T wave inversion. what does a decrease in systolic pressure mean if diastolic doesn't change? - This = narrowi...

T/F: Current exists in an ideal capacitor only when its voltage is changing True T/F: In a series capacitor circuit, the largest value of capacitance will have the smallest amount of voltage dropped across it. True T/F: In a series capacitor circuit, the largest value of capacitance will have the largest share of total charge on its plates False T/F: Magnetic lines of force never cross one another True T/F: Current flowing through a conductor creates a magnetic fi...
