Misleading exercise electrocardiograms.

Electrocardiograms of healthy men after strenuous exercise.

Between August 1954 and May 1957, 682 R.A.F. officers and men volunteered for a study of the electrocardiogram after exercise. Of these, 660 were selected because they had no symptoms, no clinical or radiological evidence of heart disease, a diastolic blood pressure of below 100 mm. Hg, and a normal 12-lead electrocardiogram taken at rest. Certain minor electrocardiographic changes that are bel...

Maximum treadmill exercise test in patients with abnormal control electrocardiograms.

Yield of ischaemic exercise electrocardiograms in relation to exercise intensity in a normal population.

Maximal bicycle ergometer exercise in an asymptomatic male population, aged 40-65 years, revealed 63 subjects with 'ischaemic' ST changes. The work intensity at the time of appearance of this change was expressed as actual heart rate as a per cent ofmaximum heart rate, and oxygen uptake as a per cent ofmaximal oxygen uptake. If the exercise had been stopped at a target heart 'rate of 85 per cen...

Interesting electrocardiograms.

The ECG showed normal sinus rhythm at 65 per min., with a very short P-R interval (0.10 sec.). On the fourth beat of the first lead set (simultaneous leads I, II, III), which is marked with an arrow, there is an atrial premature, contraction. This latter beat has a low, rather flat P wave preceding the QRS with a P-R interval of 0.20 sec. The contrast between the sinus beats (with short PR) and...

Misleading Reference

We just became aware that the article [1] published in Entropy 2009 contains a false reference. From the list of references in [1] one gets the impression that the manuscript [2] has been accepted for publication in the journal Biophyical Chemestry. We have contacted the editors of that journal and they could tell us that [2] is a rejected manuscript, which is also the reason why the manuscript...
