Tall QRS

tall QRS complex is hard to define. By the Sokolov-Lyon criteria, the QRS is large if the S wave in V1 + R in V5 or V6 is more than 35 mm. A tall QRS complex is most often associated with left ventricular hypertrophy, but additional criteria must be met to make this diagnosis. The QRS voltage may also be high in lean, athletic patients without evidence of hypertrophy.

A 50-something woman with chest pain, BP 230/120, and LBBB with 7 mm ST Elevation 31864

This ECG is from a woman in her 50s who presented with chest pressure on a background of heart failure and hypertension. BP 223/125.

This ECG shows sinus rhythm, LBBB and anterior ST elevation. Sgarbossa positive but modified sgarbossa negative. Echo showed LVH, troponin did show a rise and fall, MIBI showed normal perfusion. The most likely cause was a type II MI. The ECG changes did not evolve and were likely baseline changes.

ECG Blog #166 (ST-T – AFib – LVH – SVT) 30680

This ECG is from a woman in her 60s who presented in acute heart failure with dyspnoea and intermittent chest discomfort.

This ECG shows atrial fibrillation, LVH and diffuse ST-T changes.

LVH with expected repolarization abnormalities, or acute OMI? 30404

This ECG is from a patient who presented with acute chest pain on a background of diabetes.

This ECG shows LVH and inferior ST elevation with depression in aVL (slight). This was new in comparison to the baseline ECG. The cause was most likely a RCA narrowing.

Is this terminal QRS distortion? Is there LVH? 30422

This ECG is from an otherwise healthy, thin, African American male.

This ECG shows high voltage QRS and ST elevation with J waves, without discordant ST depression and T wave inversion, likely due to early repolarisation in a young person with a thin chest wall.

This ECG is from a teenage male who presented for a routine sports physical. He is African American.

This ECG shows high voltage with benign T wave inversion. Echocardiography did not show any evidence of HOCM.

Profound ST Elevation in V1-V3. What do you think? 28911

This ECG is from a patient of unknown age who had a systolic BP of 220 mm HG and no ischemic symptoms.

This ECG shows tall QRS complexes meeting LVH criteria with anterior ST elevation. Echo confirmed marked left ventricular hypertrophy only.

Two cases of ST Elevation with Terminal T-wave Inversion – do either, neither, or both need reperfusion? 28747

This ECG is from a teenage male who presented with chest tightness and shortness of breath for 6 hours on a background of asthma.

This ECG shows sinus rhythm with tall QRS and associated repolarisation changes, benign T wave inversion in V3-V6 with J-waves and ST-elevation.

ECG of the Week – 5th November 2018 – Interpretation 27729

This ECG is from a man in his 70s who presented with epigastric pain on a background of hypertension.

This ECG shows LBBB and occasional PVCs with discordant changes that do not meet Sgarbossa criteria. The patient self-discharged against advice before an echo could be completed for possible LVH.
