Pathology: Dyrshythmia Flashcards
What are Ectopic foci?
What is the mechanism that it causes Cardiac dysrhythmia?
Can cause *Abnormal automaticity of the heart*
Describe what happens to the P and QRS of a 3° AV Block (complete) heart block?
- What areas of the cardiac electrical conduction pathway are affected when alterations in “Sinus Rhythm” are seen?
- Are alterations in “Sinus Rhythm” common?
What type of Atrial dysrhythmia is shown?
What condition can be described as a “polymorphic ventricular tachycardia with a long QT interval” that manifsts as QT elongation followed by Ventricular Tachycardia?
Torsades De Pointes
What are the risks and transient symptoms of Torsades De Pointes?
What kind of Atrial dysrhythmia is shown?
What happens to the PR interval in a 1° AV Block? What kind of treatment is required for it?
What kind of Ventricular dysrhythmia is this?
What actually is a Premature atrial contraction?
If your heart’s electrical system triggers the early or extra beat in the atria, the result is a premature atrial contraction.
What type of heart block is shown?
What is “Sick Sinus Syndrome”?
What kind of Ventricular dysrhythmia is this?
What type of atrial dysrhythmia is shown?
What type of atrial dysrhythmia is shown?
What type of heart block is shown?
What mechanism, besides abnormal automaticity, can cause cardiac dysrhythmia?
Differentiate between Asystole, Arrhythmia, Dysrhythmia, and Ventricular fibrillation,
What are the main types of heart blocks?
- 1° AV Block
- 2° AV Block [Mobitz Type I or Wenchebach]
- 2° AV Block [Mobitz Type II]
- 3° AV Block (complete)
In a 2° AV Block [Mobitz Type I or Wenchebach], what happens to the following
- PR interval
- QRS complex
What are the causes of Torsades De Pointes?
Give the general causes (not mechanisms) of Dysrhythmia
What is the common cause for heart blocks?
What are the three general treatment options for Atrial Dysrhythmia?
What type of heart block is Lyme disease associated with?
3° AV Block (complete)
What happens to the PR interval in a 2° AV Block [Mobitz Type II]? Why is this type of heart block especially risky, and how is it treated?
What kind of heart block is shown?
- Do heart blocks cause dysrhythmia?
- Do they affect CO?
What kind of Ventricular dysrhythmias is this?
Torsades De Pointes
What kind of Ventricular dysrhythmia is this?
What occurs in a Bundle Branch Block?
What are the 4 main types of Atrial dysrhythmias?
What is a deadly risk of Atrial dysrhythmias?
-
Premature atrial contractions
- PAC
- (Paroxysmal) Atrial tachycardia
- PAT
- Atrial flutter
- Atrial fibrillation
PFPF
Risk for Blood Clot Formation
- What are three main types of Ventricular dysrhythmias, and which one is most common?
- Do they affect cardiac output?
- Ventricular premature beats aka Premature Ventricular Contractions
- PVC
- Most common and can progress to Ventricular Fibrillation
- Ventricular Tachycardia
- Ventricular Fibrillation
