Normal Sinus Rhythm - ANS Refers to a rhythm that originates in the SA node @ a rate of 60-100 BPM and follows the normal conduction pattern of the cardiac cycle. Sinus Bradycardia - ANS The conduction pathway is the same as that in sinus rhythm but the SA node fires @ a rate of less than 60 BPM. Maybe normal for athletes. Symptomatic Sinus Bradycardia S/S - ANS Pale, cool skin, hypotension, weakness, angina, dizziness or syncope, confusion or disorientation, and...

Telemetry with pictures 25 Questions with Verified Answers normal sinus rhythm - CORRECT ANSWER - normal intervals - rate 60-100 - walks out sinus bradycardia - CORRECT ANSWER - SA node in control - rate <60 - normal intervals - walks out - treat with atropine IV push sinus tachycardia - CORRECT ANSWER - SA node in control - rate >100 - normal intervals - walks out - treat with vagal maneuvers, BBs, or CCBs atrial fibrillation - CORRECT ANSWER - SA node not in control...

Automaticity correct answer: Ability to initiate an impulse at a regular interval; "pacemaker" Excitability correct answer: Ability of the heart to respond to a stimulus Conductivity correct answer: Ability of the heart to transmit an electrical impulse from one cell membrane to another Contractility correct answer: The ability of the heart muscle cells to shorten in response to an electrical stimulus Refractoriness correct answer: "Resistant to"; cannot respond to a stimulu...

What is the 5 step approach to EKG analysis? 1. Heart rate 2. Heart rhythm 3. P wave 4. PR interval 5. QRS complex What is the 6 second method of reading HR? (30 boxes) Denotes a 6 second interval on EKG strip Strip is marked by 3 or 6 second tick marks on the top or bottom of the graph paper Count the number of P waves or R waves within a 6 second strip, and then multiply that number by 10 00:42 01:13 How do you determine atrial rate? Count the number of P wave...

Relias Dysrhythmia Basic Test Answers normal sinus rhythm heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute Sinus Arrhythmia Appearance is ALMOST NORMAL: Respiratory – Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) Sinus Bradycardia <60 normal sinus rhythm Sinus Tachycardia >100 (100-150) normal sinus rhythm Premature Atrial Contraction (PAC) Heart Rate: Depends on underlying rhythm Regularity: Interrupts the re...

If there is a P-wave, the rhythm will be called "___________" something.... correct answers"sinus" where in EKG does Atrial Repolarization occur? correct answersAtria repolarization actually occurs during QRS wave but you cannot detect it __________ means any type of abnormal beat (came somewhere else besides SA node) correct answersEctopic PR interval: long or short? Long PR interval would indicate something blocking the ________________signal (some type of block). Ie: lack of p...
