Q

How does supraventricular tachycardia present on an ECG?

A

rate>100bpm

QRS complex duration <120ms (narrow complex)

30
Q

what is shown on this ECG?

A

supraventricular tachycardia

31
Q

management of acute and chronic supraventricular tahcycardia

A

ACUTE:

  • valsalva/carotid massage
  • IV adenosine/IV verapamil
  • if compromised DCCV

CHRONIC:

  • avoid stimulants
  • radiofrequency ablation therapy
  • BB
32
Q

How does ventricular fibrillation present on an ECG?

A
  • irregularly irregular
  • no QRS
33
Q

what is shown on this ECG?

A

ventricular fibrillation

34
Q

how to manage ventricular fibrillation?

A
  • defib
  • CPR
35
Q

how does ventricular tachycardia present on an ECG?

A
  • rate>100bpm
  • QRS duration>1.2s (borad complex)
36
Q

what is shown on this ECG?

A

ventricular tachycardia

37
Q

how to treat acute ventricular tachycardia?

A

Unstable- DCCV

Stable- consider pharmacologic cardioversion with AAD, in meantime prepare for DCCV

38
Q

what to do if unsure if it is VT or something else?

A

test using adenosine

39
Q

management for chronic ventricular tachycardia?

A
  • correction ischaemia if possible (revascularisation)
  • optimise congestive heart failure therapies
  • ICD if life threatening
  • VT catheter ablation
40
Q

anti arrhythmic drugs given for VT?

A

none, data has shown them to be ineffective and associated with worse outcomes

41
Q

how does Wolff-Parkinson White Syndrome present on ECG?

A
  • delta waves (slurred upstroke)
  • short PR interval
  • secondary ST changes
42
Q

what does this ECG show?

A

Wolff-Parkinson White syndrome

43
Q

what to do if patient has supraventricular tachycardia, valsalva failed and BP is 85/65mmHg?

A

-DCCV for tachyarrhythmias when systolic BP<90mmHg
