Fragmented QRS

fragmented QRS has a normal width but may have one or more additional R waves or S wave notches. It is a nonspecific sign, but if occurring in two contiguous leads it can suggest scarring from an old myocardial infarction.

Instructors’ Collection ECG : Syncope and tachycardia 29273

This ECG is from a man in his 50s who presented with syncope on a background of diabetes, opiate abuse and possible prior cardiac disease.

This ECG shows a supraventricular tachycardia with evidence of P waves, left axis deviation and slightly wider QRS (106 msec) likely due to LAFB, tall QRS concerning for LVH and fragmentation in V2-4 suggesting prior MI.

Sudden Chest pain and SOB with a Wide Complex Tachycardia 26151

This ECG is from a man in his 60s who presented with sudden onset severe chest pain and dyspnoea. He had no medical history or medications. On arrival he was in extremis with altered mentation, cyanosis and diaphoresis . There was no palpable radial pulse. Pulse oximetry read HR 170 and saturation 53%. This was the initial ECG.

This ECG is from a woman in her 70s who presented with chest pain and shortness of breath after several days of nausea and diarrhoea.

This ECG shows LBBB and appropriately discordant ST segments. The QRS is wider and the PR interval is longer than the previous ECG. The cause was hyperkalemia (7.2).

This ECG is from a woman in her 70s who presented with chest pain and shortness of breath after several days of nausea and diarrhoea. This was the repeat ECG after treatment for hyperkalemia.

This ECG shows the QRS is less wide and PR isn't as long. This is consistent with treated hyperkalemia.
