ST elevation in recovery post exercise with normal coronary arteries

Autor: Suhaib Magdi El-Omar, Reza Aghamohammadzadeh, Magdi El-Omar, Derek J. Rowlands

Publikováno v: BMJ Case Rep

We present the case of a 45-year-old healthy man who successfully completed three stages of the Bruce protocol but developed inferolateral ST segment elevation in the recovery phase. The ECG change was associated with a marked drop in blood pressure.

The Resting ECG

Autor: Derek J. Rowlands

Publikováno v: Medicine. 30:9-17

More than 100 years since the first ECG recording, the resting 12-lead ECG remains an essential part of any cardiovascular assessment. It has been estimated that more than 100,000,000 12-lead ECGs are recorded annually worldwide.

Spurious atrial tachycardia in a pilot. Prediction of the artifactual appearances in all twelve leads, when a single limb lead is the source of the artifact

Autor: Derek J. Rowlands, Philip R. Moore

Publikováno v: Journal of Electrocardiology. 40:475-477

A routine screening electrocardiogram on a amateur pilot revealed what was initially thought to be an episode of atrial tachycardia. Minutes later, the record was within normal limits. The initial reading contained an artifact. A clear explanation of

Graphical representation of QT rate correction formulae: an aid facilitating the use of a given formula and providing a visual comparison of the impact of different formulae

Autor: Derek J. Rowlands

Publikováno v: Journal of electrocardiology. 45(3)

The QT interval on the electrocardiogram is an increasingly important measurement, especially in relation to drug action and interaction. The QT interval varies inversely as the heart rate and numerous rate correction formulae have been proposed. It

Inadvertent interchange of electrocardiogram limb lead connections: analysis of predicted consequences part II: double interconnection errors

Autor: Derek J, Rowlands

Publikováno v: Journal of electrocardiology. 45(1)

Limb lead connection errors are known to be very common in clinical practice. The consequences of all possible single limb lead interconnection errors were analyzed in an earlier publication (J Electrocardiology 2008;41:84-90). With a single limb lea
