14. Ambulatory electrocardiographic monitoring in patients with transient focal cerebral ischaemia.
Sixty-four patients with transient ischaemic attacks were investigated for the presence of an associated cardiac arrhythmia. 24-hour ambulatory monitoring showed arrhythmia in 41% of patients where the standard ECG had shown arrhythmia in only 25%. Significant arrhythmias were found in 21% of patients with focal transient ischaemic attacks on prolonged monit

15. Cardiac rhythm in hypertension assessed through 24 hour ambulatory electrocardiographic monitoring. Effects of load manipulation with atenolol, verapamil, and nifedipine.

16. Continuous ambulatory pulmonary artery pressure monitoring. A new method using a transducer tipped catheter and a simple recording system.
A transducer tipped catheter and simple recording system were used for the continuous measurement of ambulatory pulmonary artery pressure. The pulmonary artery pressure was recorded on a miniaturised tape recorder and replayed via an optical writer. Pulmonary arterial systolic and diastolic pressures can be analysed on a beat to beat basis. Continuous ambula

17. Effect of exercise training on the total ischaemic burden: an assessment by 24 hour ambulatory electrocardiographic monitoring
Objective—To examine the effect of prolonged high intensity exercise training on total ischaemic burden in men with chronic stable angina pectoris.

18. Ambulatory electrocardiographic ST segment changes in healthy volunteers.
Twenty four hour ambulatory monitoring was performed on 120 healthy volunteers using a frequency modulated recorder: 50 men and 50 women below 40 years and 20 men between 40 and 60 years were studied. Twenty eight subjects had episodes of ST segment elevation (range 1-3 mm), which occurred almost invariably at night with a slow heart rate 62.4 +/- 10.4 beats

19. Electrophysiological abnormalities in the transplanted human heart.
Fourteen relatively long term survivors of cardiac transplantation underwent systematic electrophysiological evaluation and ambulatory electrocardiographic monitoring. Six patients had prolonged conduction intervals during sinus rhythm. Sinus node function could be assessed in all donor atria and in 10 recipient atria. Sinus node recovery times were prolonge

20. Disturbances of cardiac rhythm and conduction in familial amyloidosis with polyneuropathy.
Sixteen consecutive patients with familial amyloidosis with polyneuropathy of varying duration and severity underwent 24 hour ambulatory electrocardiographic monitoring. A high incidence of sinus node dysfunction, supraventricular and ventricular arrhythmias, and disturbances of atrioventricular conduction was found. Considerably more arrhythmias and disturb

21. Ambulatory ST segment monitoring. Problems, pitfalls, solutions, and clinical application.
The introduction of frequency modulated recording systems for ambulatory electrocardiographic monitoring (Oxford Medilog mark 2 and Cardiodyne cassette recorders) prompted comparison with a conventional direct recording type of recorder (Oxford Medilog mark 1). The recordings obtained by the frequency modulated recorders were very much superior to those obta

22. The heart in Friedreich's ataxia.
Seventeen patients with Freidreich's ataxia were investigated for cardiac abnormalities using non-invasive methods. Clinical examination, routine chest radiographs and electrocardiograms were a poor guide to underlying heart involvement but using continuous ambulatory electrocardiographic monitoring, echocardiography and isotope ventriculography all patients

23. The heart and tuberous sclerosis. An echocardiographic and electrocardiographic study.
Cross sectional echocardiography, 12 lead electrocardiography, and 24 hour ambulatory electrocardiography were performed in eleven patients with tuberous sclerosis. Echocardiography showed single or multiple intramyocardial masses, most commonly in the ventricular septum, suggestive of rhabdomyomata in seven of the eleven cases. One patient with a normal ech

24. Clinical sustained uniform ventricular tachycardia in hypertrophic cardiomyopathy: association with left ventricular apical aneurysm.
Of 51 patients with hypertrophic cardiomyopathy who had episodes of ventricular tachycardia detected during ambulatory electrocardiographic monitoring only two had clinical sustained uniform ventricular tachycardia that required medical treatment because of worsening symptoms. In both patients the arrhythmia was associated with the uncommon finding of an api
