Vectorcardiographic Changes During Intracoronary Injections

Vectorcardiographic changes during intracoronary injections.

Comparison of serial electrocardiographic and vectorcardiographic changes during recovery from status asthmaticus.

Serial electrocardiographs (ECG) and vectorcardiographs (VCG) have been performed on 10 patients admitted to hospital in status asthmaticus on 12 separate occasions. The VCG was more efficient than the ECG in the detection of right atrial and ventricular enlargement. Both investigations were equally reliable in recording changes in frontal plane P wave axis. The mean frontal plane P wave axis f...

Vectorcardiographic Changes During Exercise Test - Correlates to Lactate and Anaerobic Threshold?

The aim of the study was to investigate the correlations between blood lactate concentration, different vector ECG (VECG) parameters, ventilatory parameters and heart rate during exercise and recovery periods. Six (25-37 years old) non athlete, healthy, male subjects participated in the study. All subjects performed two different bicycle ergospirometric protocols (P1 and P2). The aim in using t...

Thrombotic complication during intracoronary imaging

Intracoronary imaging with intracoronary ultrasound and coherence tomography is often used in the follow-up of coronary stent implantation. The present case shows an infrequent complication of these procedures, suggesting our continued attention to the selective use of these invasive procedures.

Serum Changes following Kaolin Injections

1. The intoxication produced by the intravenous injection of inert substances such as kaolin is due to protein split products derived from the serum proteins. 2. The kaolin acts as an adsorbing medium for the serum antiferment, bringing about an alteration in the ferment-antiferment balance. 3. The intoxication is accompanied by an increase in serum protease, and of proteoses. 4. The serum lipa...
