QuestionChoice
This could be identified on an ECG as a PR interval of over 200ms. This patient has delta waves on their ECG which is suggestive of Wolff-Parkinson White syndrome.

First degree heart Block
QuestionChoice
Atrial fibrillation is uncoordinated contraction, which causes a heart beat of 300-600 beats per minute. An ECG would show an irregularly irregular pulse rate. This patient has delta waves on their ECG which is suggestive of Wolff-Parkinson White syndrome.

Atrial Fibrillation
QuestionChoice
On ECG, 3rd degree heart block would show bradycardia and complete dissociation between the P waves and QRS complexes. This patient has delta waves on their ECG which is suggestive of Wolff-Parkinson White syndrome.

c
3rd degree heart block
QuestionChoice
Atrial flutter is caused by an aberrant macro-circuit within the right atrium. The heart can beat at up to 300 beats per minute. An ECG of atrial flutter would show a saw-tooth pattern and narrow QRS complexes. This patient has delta waves on their ECG which is suggestive of Wolff-Parkinson White syndrome.

Atrial flutter
QuestionChoice
This presentation is most likely to be Wolff-Parkinson White syndrome. Delta waves (which are slurred upstrokes of QRS) indicate Wolff-Parkinson White syndrome. ECGs may also show a shortened PR interval, broad QRS complex, or narrow complex tachycardia. This condition is caused by an extra accessory pathway that bypasses the AV node.

A 19-year-old female is brought to the emergency department after a sudden collapse at home. She has no diagnosed medical conditions, but has been undergoing investigations in her GP surgery for unexplained palpitations.

Her ECG demonstrates a normal sinus rhythm, with the presence of delta waves.

Which of the following is the most likely cause of her collapse?
