QuestionChoice
The ECG shows a supraventricular tachycardia (SVT) with a regular rhythm, in the context of a clinically stable patient. The first line management is a Valsalva manoeuvre. By contrast, cardioversion should be used in a patient in SVT who is unstable and has adverse features such as heart failure, ischaemia, shock or syncope.

Synchronised direct current cardioversion
QuestionChoice
The ECG shows a supraventricular tachycardia with a regular rhythm, in the context of a clinically stable patient. The first line management is a Valsalva manoeuvre. This aims to increase vagal tone and slow the conduction through the atrioventricular node, thus leading to a slowing of the heart rate.

The ECG shows a supraventricular tachycardia (SVT) with a regular rhythm, in the context of a clinically stable patient. By contrast, flecainide is the pharmacological management for rhythm control in a patient with fast atrial fibrillation.

QuestionChoice
The ECG shows a supraventricular tachycardia with a regular rhythm, in the context of a clinically stable patient. The first line management is a Valsalva manoeuvre. By contrast, adenosine is the treatment of choice in a stable supraventricular tachycardia if vagal manoeuvres have failed. Adenosine temporarily blocks the conduction through the AV node and should always be followed by 20ml IV normal saline. Patients must be warned about experiencing difficulty in breathing, chest tightness and flushing.

Adenosine 6mg
QuestionChoice
The ECG shows a supraventricular tachycardia (SVT) with a regular rhythm, in the context of a clinically stable patient. By contrast, amiodarone is used mainly for stable patients with a broad complex tachycardia or for both rate and rhythm control in atrial fibrillation. It is not the first line management for SVT.

A 65 year old male patient is brought into A&E by ambulance. He had been feeling generally unwell with palpitations and dizziness for the last 3 hours. The paramedics state the only past medical history of note is high cholesterol for which the patient takes atorvastatin and they have no allergies. The paramedic crew have not yet administered any treatment.

Observations are as follows:
HR: 156bpm.
RR: 22.
BP: 130/78.
Temp: 36.7.
O2 Sats: 98% on room air.
BM: 6.2mmol.

Blood tests and a chest x-ray are requested. The ECG shows a supraventricular tachycardia with a regular rhythm

Which of the following is the first line management of this patient's condition?
