TAILIEUCHUNG - ECG at a Glance - Patrick Davey 2

(BQ) Part 2 book "ECG at a glance" presents the following contents: Emotion and the ECG, acute coronary syndromes, sudden cardiac death, aortic valve disease and hypertrophic cardiomyopathy, mitral valve disease, congenital heart disease, pulmonary hypertension, psychological disease and its treatment,. and other contents. | Emotion and the ECG 66 Clinical syndromes Emotion and the ECG Emotion can affect the ECG Emotion can affect the ECG two ways Firstly by causing asymptomatic ECG changes leading to an erroneous diagnosis of heart disease. These changes are limited to ST T wave changes . not involving the development of a Q wave or changes to the QRS complex . Secondly much more rarely by causing organic cardiac disease such as standard myocardial infarction arrhythmias or the syndrome of transient left ventricular dysfunction. Diagnostic difficulties An extraordinary common difficult problem in clinical practice is to decide whether an abnormal ECG reflects cardiac pathology or not with the ECG changes being explained by anxiety or hyperventilation. Anxiety-related ECG changes Anxiety can profoundly alter the ECG probably via changes in autonomic nervous system function as evidenced by the ECG normalizing with manoeuvres that normalize autonomic function reassurance rest and anxiolytics and beta-blockers with catecholamine infusion producing similar ECG changes. The ECG changes in anxiety are ST flattening the commonest finding. Frank ST depression not rare especially in hyperventilation. T wave inversion How does one differentiate anxiety-induced changes from those reflecting cardiac disease Fully assessing demographics age sex etc. and symptomatology are the keys to a correct diagnosis. Though one can often be fairly confident that some patterns are due to anxiety one cannot always be 100 certain so it is not uncommon to undertake further limited investigations to exclude heart disease always explaining beforehand that the result is likely to negative and the test is required only for reassurance. ST elevation and emotion 1 Emotion can provoke ST segment elevation myocardial infarctions STEMIs in pre-existing coronary artery disease. 2 Tako-tsubo syndrome rare in elderly women where stress induces reversible left ventricular dysfunction of a specific pattern extending beyond .
