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

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...

Status asthmaticus

Status asthmaticus (SA) is a common medical emergency faced by emergency department and intensive care specialists. Timely evaluation and treatment is required to prevent the morbidity and mortality associated with respiratory failure. SA is a severe asthma exacerbation that proves refractory to standard treatment regimens and represents the most extreme end of the asthma spectrum. Research eff...

Status asthmaticus.

Status asthmaticus, or acute severe asthma [ 1 ], is a potentially life-threatening episode of severe asthma failing to respond to usually effective or increasing amounts of inhaled [32-adrenergic agonists and theophylline preparations . Such an acute episode of asthma is often preceded by inadequate control of symptoms over the preceding weeks with more rapid deterioration 24 h immediately bef...

Electrocardiographic changes during oesophagogastroscopy.

BACKGROUND Oesophagogastroduodenoscopy (EGD) should be very safe, but there are many potential hazards, although the rate of serious complications is small. There are so many complications that can arise during this procedure. Most of these complications involve the respiratory or cardiovascular systems, especially in sick or sedated patients.The aim of this study was to determine the various e...
