1. Sudden onset palpitations

ECG shows regular narrow complex tachycardia with rate around 140

We suspected this was atrial flutter
Rather than subject a patient to the horror of iv adenosine (which only reveals flutter - it can’t convert it), we moved the ECG limb leads around to get a ‘Lewis lead’ which better shows atrial activity

(See https://litfl.com/lewis-lead-s5-lead/ )

This revealed quite clear evidence of atrial flutter

After some fentanyl, a checklist, some white medicine and 50 Joules of synchronised electricity, the patient was in sinus rhythm and discharged to follow up with his cardiologist after observation on the ED Short Stay Unit

2. A patient who had had a transcatheter aortic valve implantation (TAVI) a few days earlier came in feeling dizzy

He has complete heart block

Conduction problems are a well recognised complication of TAVI due to the close proximity of the aortic root and conduction tissue

He was normotensive and mentating normally with good skin perfusion and a normal lactate

He did not require intervention in the emergency department and was admitted for pacemaker insertion

3. A man walked in with a 30 minute history of severe chest pain

A diagnosis of anterolateral STEMI was made. Cath lab was activated and he was given fentanyl, aspirin, ticagrelor and heparin

The on call interventional cardiologist was still on his way in when other cath lab staff were ready

Normally the patient should stay in ED until the cardiologist is ready but we suggested bringing him up anyway to reduce delays and reassured the cath lab nurses we would stay with him until the cardiologist arrived

This enabled the patient to have wrist and groin prepped and draped and was ready for intervention as soon as the cardiologist arrived (ED registrar and cath lab nurse shown in image)

Summary from today’s cardiology patients in the ED:

1. Lewis lead unveils atrial activity that’s difficult to identify on standard ECG

2. Conduction problems can occur after TAVI

3. EM & Cardiology can work together to devise local solutions to minimise reperfusion delays
