dysrhythmia aka arrhythmia - Correct answer - abnormal cardiac rhythms which can cause disturbances of: rate, rhythm, or both rate and rhythm how are dysrhythmias identified? - Correct answer Electrographic Waveform Analysis (ECG) what controls the rate and rhythm of the heartbeat? - Correct answer the heart's electrical system explain the heart's electrical system - Correct answer Each electrical signal (impulse) begins in a group of cells called the sinus node or sinoatrial (SA...

CCT-CCI questions with correct answers On a cardiac rhythm strip, which of the following can determine if the patients heart rate is regular? The RR intervals being equal. The PP intervals being equal. The RR intervals being unequal. Both A and B Answer If the RR or PP intervals are not equal, then the rhythm is irregular. One of the most uncommon rhythms that is always unequal is atrial fibrillation. If the physician orders a treatment for a patient that is supposed to help prevent ...

STARN EKG TEST (NON LETHAL RHYTHMS) UPDATED VERSION 2024 BEST FOR REVISION. 2 / 7 1. Accelerated Junctional: Rate: 60-100 Rhythm: Regular Pwave: before/after/absent - inverted PR: unknown QRS: Normal *** Fast junctional escape 2. Asystole: absence of contractions of the heart-Flat Line 3. Atrial fibrillation: rapid, random, ineffective contractions 4. Atrial Flutter: Rate:Atrial 250-350 Ventricular: 100 -175 P:Irregular or absent, often "saw tooth" QRS: Normal Conduction: AV Blo...

Arrhythmias correct answers not a normal heart rhythm can be benign or life threatening result in a decreased Cardiac Output (CO) and decreased tissue perfusion unstable correct answers only treat if p.t is not ___ so have to have symptoms like diahorhesis, hypotension, pale automaticity correct answers ability of cardiac cells to initiate electrical impulse (heart beat): _____ contractility correct answers ability to shorten in response to electrical impulse: ______ conductivity c...

HEALTHSTREAM TELEMETRY & ECG EXAM 2023/2024 Mechanical & Electrical Activity - CORRECT ANSWER-- Correlation between the electrical and mechanical functions of the heart - Electrical activity stimulates the heart to contract - Electrocardiogram (ECG) show both functions - Electrical pulse= action potntial Cardiac Monitoring - CORRECT ANSWER-- Used to diagnose dysrhythmias, chamber enlargement, MI/myocardial ischemia, monitor effects of electrolyte imbalances of medication administrat...

what is the rate of atrial flutter rhytms? correct answers 250-350 bpm what is the heart rate for junctional escape rhythm? correct answers 40-60 bpm, if the P wave is identifiable 2nd degree block (Mobitz type I) correct answers PR interval starts normal then widens till it loses the QRS then the cycle begins again Ventricular Tachycardia correct answers 3 more more PVC occurs in a row and the ventricular rate is greater than 100 bpm 3rd degree block correct answers missing QRS, sho...

Describe treatment of dysrhythmias correct answer: To determine if treatment is necessary, assess the patient. Then ask the following questions: Is he or she experiencing signs and symptoms of decreased cardiac output? Is the dysrhythmia potentially life threatening? If the answer to either of these questions is yes, the patient will need to treatment for the dysrhythmia. ***WE WILL DISCUSS TREATMENTS OF DYSRHYTHMIAS BASED UPON CURRENT ACLS TREATMENT ALGORITHMS CLINICAL MANIFESTATIONS ...

CARDIAC HEALTHSTREAM TELEMETRY EXAM Q & A 2023/2024 Normal Conduction System - CORRECT ANSWER--SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm -Internodal Pathways = Pathways connecting SA Node and AV Node -AV Node = Backup pacemaker, rate of 40-60 bpm -Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system of heart -L & R Bundle Brancehs = lead to left & right of the myocardium -Purkinje Fibers / Network = ends of the muscle, last...
