1. The electrocardiogram was recorded for 3 min during spontaneous respiration in 70 subjects aged 15-86 years who were in sinus rhythm. Using a signal-averaging approach, the presence of respiratory variation of P-P intervals was analysed by multiple regression against a cosine function (cosinor analysis). 2. By cosinor analysis the phase of respiration(More)
1. In 50 subjects with atrial fibrillation we have attempted to demonstrate variation of ventricular rate with respiration, as evidence of cardioregulatory reflex activity. 2. The electrocardiogram was recorded for 3 min during spontaneous respiration. The presence of respiratory variation of R-R intervals was analysed by multiple regression against a(More)
The outcome of 1011 heart attacks in patients under the care of general practitioners who practised cardiopulmonary resuscitation and were equipped with defibrillators is reported. The 28 day mortality was 36% (367 patients), and 59% of deaths occurred outside hospital. The general practitioner was the first medical contact in 92% of heart attacks and was(More)
The electrocardiogram was recorded for 100 seconds in 50 patients with atrial fibrillation to determine the relations between QT intervals and both the mean and instantaneous ventricular rates. The mean ventricular rate was 94 beats per minute with a mean QT interval of 357 ms. The mean QTc, corrected beat by beat with Bazett's formula, was 444 ms--longer(More)
A 9-year-old girl presented with a 2-year history of pigmented streaks on her second right toenail as well as on her fourth and fifth left toenails. The patient was otherwise asymptomatic with no other physical findings. Owing to parental concern, a biopsy was performed, which revealed numerous bacteria as well as Medlar bodies overlying the nail bed with(More)
An 18 year old girl presented with frequent vasovagal attacks and sinus arrhythmia. The amplitude of respiratory sinus arrhythmia assessed by cosinor analysis was 20%; the predicted value for a normal girl of this age is 4% and the 95% confidence interval is 0-8%. Treatment with propantheline, in a dose sufficient to reduce the amplitude of sinus arrhythmia(More)
Out of 156 cases of various gastro duodenal disorders studied H. pylori was diagnosed in 119 (76.28%) as indicated by Biopsy urease test and IgG ELISA. Biopsy urease test detected higher number of cases 119 when compared to IgG ELISA 107 cases. ELISA being a non invasive technique can be used successfully for the diagnosis of H. pylori infections.
