ECG diagnosis?

1. 1. 6 years old girl child came with episodic and brief left sided chest pain

These episodes do not have a clear triggers but comes and goes under a minute. Child describes as sharp

No other significant history except febrile fits

An ECG was taken

• 1. 1. Sinus rhythm with pre-excitation

• 2. 2. Complete AV block with junctional escape rhythm

• 3. 3. Sinus  rhythm with premature atrial contractions

• 4. 4. Isorhythmic AV dissociation due to enhanced junctional automaticity

• 5. 5. Sinus Arrhythmia

2. 2. 72 years old female experienced a brief dizziness taking a few steps after standing. She is on treatment for HT with HCT and Losartan

   Family took her to nearest GP where this ECG was taken

   Because of abnormal ECG’ GP referred for specialist’s opinion

• 1. 1. Sinus bradycardia

• 2. 2. Sinus bradycardia with 1st degree AV block

• 3. 3. Sinus bradycardia with 1st degree AV block and IVCD

• 4. 4. Sinus bradycardia with 1st degree AV block, IVCD and QT prolongation

• 5. 5. Sinus rhythm with pseudo-bradycardia

3. 3. 32-year-old HCW fainted in the labour room while on duty

No similar episodes in the past

PMH is unremarkable

No significant FH of cardiac ailments

He was then admitted for observation and a 24- hour ambulatory ECG was hooked

• 1. 1. Artifact

• 2. 2. Paroxysmal atrial fibrillation

• 3. 3. Spontaneously terminating sustained monomorphic VT

• 4. 4. Spontaneously resolving PMT/ VF due to short coupled PVC

• 5. 5. Spontaneously resolving PMT/VF due to long QT

4. 56 years old female admitted with typical chest pain

She was treated for acute coronary syndrome

On the third day of hospital stay she suffered a cardiac arrest

This is her ECG before she suffered cardiac arrest

• 1. 1. Sinus bradycardia

• 2. 2. Sinus bradycardia with premature atrial complexes

• 3. 3. Sinus bradycardia with premature junctional complexes

• 4. 4. Sinus bradycardia with premature fascicular complexes

• 5. 5. Sinus bradycardia with premature ventricular complexes

5. 5. 45 years old male presented with chest pain to a local hospital

He was then transferred for immediate CA and PCI

He did not disclose but having fever too

• 1. 1. ST elevations due to acute myocardial infarction

• 2. 2. ST elevations due to pericarditis

• 3. 3. ST elevations due to old myocardial infarction and LV aneurysm

• 1. 4. ST elevations due to fever induced Brugada pattern

• 1. 5. ST elevations due to idiopathic early repolarisation

6. 6. 47 years old man underwent CA and PCI following UA

He was observed at CCU

Alarm went off!

• 1. 1. Paroxysmal AF

• 2. 2. Artifact with sinus rhythm

• 3. 3. Non sustained monomorphic VT

• 4. 4. Non sustained polymorphic VT

• 5. 5. Non sustained VF
