In this week’s View, Dr. Eagle looks at anticoagulation for post-operative atrial fibrillation after isolated coronary artery bypass grafting. He then examines a meta-analysis of invasive vs. conservative management of non-ST-elevation acute coronary syndromes with previous coronary artery bypass grafting.

By 1909 ECGs were being used to diagnose cases of arrhythmia; by 1910 to diagnose indicators of a heart attack. Another vendor to watch in this space is Israeli start-up CardiaCare, currently developing a ‘world-first’ closed-loop, neuromodulation wearable for the non-invasive treatment for AFib.

The patient was diagnosed with stress cardiomyopathy. Widespread T wave inversions and prolongation of the QT interval is not uncommon in Takotsubo cardiomyopathy. The QTc then gradually shortened over the course of several days as is usual for stress cardiomyopathy. Potassium was 4,8 mmol/l. ( ref 3,5-4,6 mmol/l ).

This is a very typical ECG for Hypertrophic Cardiomyopathy. The most recent previous was 4 years prior, and was in the normal range) Elderly patients, and patients with cardiomyopathy (including HOCM), may have troponin values in this range chronically ("chronic myocardial injury"). WPW Cardiac arrhythmias ( including AFib ).

As a result, in order to differentiate MAT from the much more commonly encountered irregularly irregular rhythm ( which is AFib ) — we need to be certain we are seeing multiple different P wave morphologies that are constantly changing. Clinically , the importance of recognizing MAT — is that treatment is different than the treatment of AFib.

The QRS is wide in B — but the rhythm is irregularly irregular with no sinus P waves — so this most probably represents rapid AFib with an atypical RBBB/LPHB morphology. We now see that QRS morphology in lead II during sinus rhythm is similar to the QRS morphology in lead II during rapid AFib (beats #1-5 in lead II in A).

That said — distinction between "classic" HCM vs the apical HCM for m may be useful because: i ) ECG findings tend to be different ( Lyon et al — Europace 20:102-112iii, 2018 ) ; — ii ) Echo appearance is different when hypertrophy localizes to the apex; and , iii ) There is a significantly greater incidence of AFib with apical HCM.
