Response to raised ICP
Acute management of bradycardia:
What 2 drugs that start with A can be given to increase the HR?
What is the definitive Rx?
Atropine IV or Adrenaline/isoprenaline infusion
Transvenous or permanent pacemaker
Pacemakers and ICD’s - what are they used for?
Why are implantable cardioverter defibrillators (ICD’s) used?
What are permanent pacemakers used for?
Used to control cardiac rhythm
Prevents sudden cardiac death
Maintain adequate HR
Pacemakers and ICD’s complications
What are some general complications?
What may happen to the lungs?
ICD malfunctions
PPM malfunctions
The pacemaker may also oversees or under sense.
Infection, bleeding
Device related pain
Acute pneumothorax
Inappropriate shocks - could be triggered by AF or malfunction
Failure to shock
Brady/tachycardia
Dysrhythmias
Sudden cardiac death
Causes - 3
Long QT syndrome
Brugada syndrome is a condition that causes a disruption of the heart’s normal rhythm. Specifically, this disorder can lead to irregular heartbeats in the heart’s lower chambers (ventricles), which is an abnormality called ventricular arrhythmia.
Arrhythmogenic right ventricular cardiomyopathy
