ECG #30

DESCRIPTION:

• Wandering baseline with interference artefact
• Ventricular rate 52 bpm
• Sinus rhythm/bradycardia
• PR interval 186 ms
• Normal QRS axis (-14°)
• Normal QRS duration (84 ms)
• Poor R wave progression with Q wave formation in precordial leads V1-3
• Downsloping ST segment depression in precordial leads V1-4
• ST segment elevation in postcordial leads V7-9
• Hyperacute T waves in lead II (± aVF), V5-6
• Pathological Q wave formation in the inferior leads (III + aVF)
• QTc 394 ms

INTERPRETATION:

Posterior ST Elevation Myocardial Infarction  with evidence of inferior wall extension. Confirmation with postcordial leads (V7-9) would be useful (see Next ECG →)
