Cardiac Dysrhythmia Exam Interpretation Review, Exams of Cardiology
A comprehensive review of various cardiac dysrhythmias, including their characteristics, diagnostic criteria, and management strategies. It covers a wide range of arrhythmias, from normal sinus rhythm to life-threatening conditions like ventricular fibrillation. Structured as a series of questions and answers, making it an effective study resource for healthcare professionals preparing for exams or seeking to enhance their understanding of cardiac electrophysiology. The detailed explanations and visual representations of the different dysrhythmias make this document a valuable reference for students, clinicians, and healthcare providers involved in the diagnosis and treatment of cardiac rhythm disorders.

- Normal sinus rhythm (NSR)
- Sinus Bradycar- dia
- Sinus Tachycar- dia
- Sinus Arrhyth- mia
- Supraventricular Tachycardia (SVT)
- Premature Atri- al Contraction (PAC)
- Atrial Flutter
- Atrial Fibrillation
- Atrial Fibrillation with RVR Rate: > Rhythm: Regular P-wave: unable to identify a P- wave PR: Unknown QRS: Normal *** Tx: Vagal response, IV adenosine push Rapid ventricular response -Ventricles are firing quicker -Decreased cardiac output -Not enough time for ventricles to fill
3 / 7
- Asystole Represents the total absence of ventricular electrical ac- tivity -No atrial or ventricular contraction -Patient unresponsive, pulseless, apneic -Must assess in more than one lead
- Pulseless Electri- cal Activity (PEA)
- First-degree AV PR > 0.2=Prolonged PR block -Prolonged Conduction from atria to ventrical
- Second-degree Rate: Atrial rate normal and slower ventricular rate AV block (Mobitz Regularity: Irregularly regular type 1- P-Wave: P-wave for every QRS, but NOT a QRS for every Wenckebach) P-wave PR interval: Some greater than 0.20 seconds
- Second-degree - normal PRI then sudden drop of QRS AV block (Mobitz - P wave doesn't always produce QRS type II) - P-R interval is constant (diff from 3rd degree)
- no hint just drops out -> is serious and dangerous pt needs tx!
- tend to be every other, so drops HR by 1/2) --> def bradycardia (rate=40bpm)
