Broad Complex Tachycardias Flashcards
What are the two types of Long QT Syndrome
Ventricular fibrillation
Torsades de Pointes
What are the ECG features of VF
Polymorphic and irregular QRS
Pulseless rhythm
What is the initial management of VF
Basic life support
Commence CPR
What are the management steps for VF
Basic life support with CPR
Administer Defibrillation (unsynchronised cardioversion)
Continue CPR
1mg Adrenaline with 300mg Amiadarone
What are the ECG features of Ventricular tachycardia
Tachycardia >100bpm
Absent P wave
Monomorphic Broad QRS
How would you manage a pulseless VT patient
Advanced life support
Defibrillation
Continue CPR
1mg Adrenaline with 300mg Amiadarone
How would you manage a VT patient with a pulse but adverse features (shock, syncope, myocardial ischaemia, heart fail)
Administer DC cardioversion (3 times)
300mg IV Amiadarone
How would you manage a VT patient with a pulse and has no adverse features
300mg of IV Amiadarone
What is Torsades de Pointes
QT prolongation causing Polymorphic VT
What are the ECG features for Torsades de Pointes
Twisting around the isoelectric line
What can cause TdP
Antiarrhythmics (Erythromycin) MI Renal/Liver fail Hypothyroid AV block
How would you manage unstable TdP patients
Synchronised DC shock
IV Amiadarone
How would you manage a stable TdP patient
IV Magnesium Sulphate Stop drugs that prolong QT Correct hypokalemia Consider... -Isoprenaline infusion -Temporary pacing -Permanent Pacing
What is Long QT Syndrome
Congenital cardiac ion channel mutation causing ventricular tachycardia and Long QT
What can cause Long QT Syndrome
Romano Ward syndrome
Hypokalemia and Hypocalcemia
