Regular

In a regular rhythm, the beats are evenly spaced apart. There are many many causes of regular rhythms, including normal rhythms like Normal Sinus Rhythm, common rhythms like Sinus Tachycardia, or dangerous rhythms like Ventricular Tachycardia.

    Tachycardia, fever to 105, and ischemic ST Elevation — a Bridge too Far

    This ECG is from a man in his 50s who presented with a high fever and dysonpea.

    This ECG shows sinus tachycardia with widespread ST elevation. He was treated for sepsis but serial ECGs and troponins were abnormal. Angiogram showed a myocardial bridge in the mid LAD.

    Instructors’ Collection ECG : Syncope and tachycardia

    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.

    ECG of the Week – 7th January 2019 – Interpretation

    This ECG is from a woman in her 20s who presented with palpitations for an hour.

    This ECG shows a regular narrow complex tachycardia (SVT) with secondary ST segment changes due to the extreme rate (205 bpm).

    Is this ST elevation normal or abnormal?

    This ECG is from a man in his 50s who presented with less than an hour of chest pain. This was his initial ECG.

    This ECG shows subtle ST elevation in V2 and V3 with a very small amount of ST depression in V4-6. He was monitored and the ECG progressed into a clear STEMI. Catheterisation showed 95% proximal LAD stenosis and occluded 1st diagonal.

    Wide-complex tachycardia: VT, aberrant, or “other?”

    This ECG is from an older woman who presented with dyspnoea, diaphoresis and chest pressure. She had a background of paroxysmal AF for which she was on flecainide.

    This ECG shows a regular wide complex tachycardia with possible flutter waves. There was no response to adenosine. The patient was electrically cardioverted. The cause was thought to be flecainide toxicity.

    Can you see through this wide complex rhythm?

    This ECG is from a man in his 70s who presented with intermittent dyspnoea and chest pain over the past 2 weeks. He had a history of a pacemaker, heart failure, aortic stenosis, diabetes, hypertension, stroke, ischemic heart disease, chronic kidney disease and peripheral vascular disease. This was his initial ECG.

    This ECG shows a wide complex tachycardia with ventricular pacing. The excessively discordant ST changes in V4-6 and aVR suggested diffuse subendocardial ischemia. He was found to have severe three vessel disease and a proximal left circumflex stenosis was stented.

    ECG of the Week – 3rd December 2018 – Interpretation

    This ECG is from a man in his 50s who had an episode of chest pain and shortness of breath. This ECG was recorded when he was pain free.

    This ECG shows sinus bradycardia with T wave inversion in the inferior leads, which was caused by reperfusion of a critical stenosis of the RCA.

    Arrhythmia? Ischemia? Both? Electricity, drugs, lytics, cath lab? You decide.

    This ECG is from a man in his 60s who presented with intermittent shortness of breath and chest pressure over the past few days. This was his initial ECG.

    This ECG shows a regular narrow complex tachycardia around 200 bpm, without P waves, with marked ST elevation in inferior leads and ST depression in anterior leads and aVL. The cause was thought to be atrial flutter from newly started flecainide. He also underwent angiography and had stents inserted to the left circumflex and right coronary arteries.

    Arrhythmia? Ischemia? Both? Electricity, drugs, lytics, cath lab? You decide. Repeat 1 min later.

    This ECG is from a man in his 60s who presented with intermittent shortness of breath and chest pressure over the past few days. This was his repeat ECG after the rhythm changed.

    This ECG shows a sinus tachycardia with ST elevation in inferior leads and ST depression in anterior leads and aVL. He underwent angiography and had stents inserted to the left circumflex and right coronary arteries.
