One presents the results of a study concerning the use of microwave Doppler transducer for contact-less detection of cardiorespiratory activity. The main element of the installation is a microwave Doppler transducer. The Doppler signal resulting from the movement of the anatomical structures is a complex one. The experimental setup also includes an electrocardiograph, a photopletismograph and a...

Congenital complete heart block could be absolutely asymptomatic. Increased awareness of suspecting an atrioventricular heart block in patients with slow heart rate and electrocardiograph examination will ensure recognition of this problem. The possibility of sudden cardiac death in these patients should not be forgotten. The goal in the peri-operative anaesthetic management is to preserve the ...

a number of epidemiologic studies have reported a positive relationship between heart rate, cardiovascular disease and mortality. to examine the correlation between heart rate and mortality after acute myocardial infarction (ami), 2147 patients hospitalized in coronary care units in isfahan were investigated in a cross-sectional study. their heart rate was measured according to an electrocardio...

Six consecutive patients studied by angiocardiography or aortography ranging in age from 12 to 68 years were checked by a direct-writer type of electrocardiograph during the procedure. The clinical entities consisted of pulmonary stenosis, coarctation of the aorta, aneurysm of the ascending aorta, ventricular septal defect (2 cases), and atrial septal defect associated with complete transpositi...

A new apparatus has been built that annexes a normal electrocardiograph, ECG, with the aim to enhance its capacity. It adds the normal ECG power to superpose multiple records of ECG altogether and averages out them and, further, makes sophisticated analysis, such as normalizing the peak heights, evaluating the half-line widths of the peaks, or that of the standard deviations of measurements lik...
