Flashcards in dysrhythmia Deck (11):
1

possible sites of origin

(Atrial, Junctional)-supraventricular or ventricular

2

True arrhythmia

very disorganised rhythm

3

Tachycardia

Fast heart beat

4

Bradycardia

Heartbeat to slow

5

Ectopic pacemaker

Tissue other then SA node initiates a heart beat

6

Delayed after depolarisation

Build up of calcium in cells causing a train of action potentials

7

Re-Entry circuit

tissue abnormality causes action potentials to travel in circles

8

Congenital abnormalities

additional conducting pathway between atria and ventricles called the Kent bundles

9

Heart block

damage to conducting pathways disrupts atrial ventricular signalling

10

three types of treatment fo dysrhythmia

Drugs, electrical, Surgical

11

Electrical treatments

implanted pacemaker, Defibrillation
