Cardiac Rhythm Therapy - correct answer Meds not working
Catheter ablation therapy destroys cells causing A. Fib
Mod sedation, IV heparin to reduce periprocedural emboli
Frequent monitoring for dysrhythmias, stroke, vascular access site complications, fluid
imbalance.
back discomfort normal d/t length of procedure
A. Flutter - correct answer • Regular atrial impulse at a rate between 250 and 400 bpm
(A. Fib is faster up to 600)
• Etiology:
Heart disease
Fluid overload
Atrial ischemia
• Rate: Atrial rate between 250-400 bpm, Ventricular rate between 75-150 bpm
• Rhythm: Atrial rhythm is regular and ventricular rhythm
is usually regular but may be irregular.
• QRS shape: Normal b/c atrial depolarization doesn't conduct through AV node.
• P Wave: Saw toothed shape, referred as F waves
• PR Interval: Difficult to determine
Sx: SoB, Hypotensions, Angina
Atrial Flutter Strip - correct answer -Saw tooth, more consistent and uniform
,-Atrial rate faster than AV node's ability to conduct -> therapeutic block @ AV node =
prevents V. FIb (lethal)
A. Flutter Meds - correct answer Ca Channel Blocker: Adenosine
-slows AV node conduction
-bolus followed by a 20ml saline flush and arm elevation to induce rapid circulation of
adenosine to heart
,• No heartbeat
• No palpable pulse
• No respirations
Asystole Nursing Interventions - correct answer High Quality CPR!
ID cause
IV Initiation!
Prepare for intubation to ensure patent airway with minimal/no interruptions to chest
compressions
Rapid cardiac rhythym analysis and Defib if in V. Tach or V. Fib
Longert pt is down = increased brain damage -> anoxic encepalopathy; want ROSC in
<5min and hypothermic therapy after to minimize brain damage
Premature Ventricular Contractions (PVCs) - correct answer - Bizarre QRS complex
- signal starts somewhere in the ventricles instead of the SA node
- ventricles dont activate in the atria while the normal sinus rhythym is buried in the
bizarre QRS complex from the premature ventricular beat
- no treatment unless 4 in a row (V. Tach at this point)
- asymptomatic/feel like heart skipped a beat
Premature Ventricular Contractions (Etiology) - correct answer - Coronary Artery
Disease
- Drug Overdose
- Electrolyte Disturbance:
Hypokalemia! (3.5-5)- can turn to V.Tach if not fixed
Hypomagnesemia (1.5-2.5)
- Caffeine, Nicotine, Alcohol
- Heart Failure
- Tachycardia
- Digitalis Toxicity
- Hypoxia
- Acidosis
Ventricular Tachycardia (V. Tach) Etiology - correct answer - Lethal rhythm = Med.
Emergency
- 3 or more consecutive PVCs at a rate of >100BPM
