[Cardiac asystole during dobutamine stress echocardiography].
We report a case of cardiac asystole during dobutamine stress echocardiography in a 59 year-old woman presenting with chest pain and a positive treadmill test for ischemia. Cardiac asystole was not associated with myocardial ischaemia and was probably related to a powerful cardioinhibitory reflex caused by dobutamine stimulation.
متن کاملPR Interval Behavior During Exercise Stress Test
OBJECTIVES The PR interval on the electrocardiogram represents conduction time from the onset of atrial activation through His-Purkinje conduction system during a normal cardiac cycle. While its behavior at rest and during exposure to various cardioactive drugs is well documented, there exist few reports which describe PR interval variations during exercise in normal control and patient groups....
متن کاملELECTROCHEMICAL NOISE ANALYSIS OF 70-30 BRASS DURING STRESS CORROSION CRACKING TEST IN MATTSON S SOLUTION
An investigation of the electrochemical noise generation during Stress Corrosion Cracking (SCC) of 70-30 Brass in Mattson's solution was conducted. The fluctuations of potential and current were monitored. The relationship between potential and current fluctuations has been evaluated in time domain and the obtained data has been analyzed in the frequency domain using Power Spectral Density (PSD...
متن کاملSyncope caused by cardiac asystole during dobutamine stress echocardiography.
Syncope caused by cardiac asystole during dobutamine stress echocardiography occurred in a 60 year old woman presenting with chest pain and a non-diagnostic exercise test. Cardiac asystole was not associated with myocardial ischemia and was attributed to a powerful cardioinhibitory vagal reflex elicited by the stimulation by the drug of cardiac and aortic mechanoreceptors. Cardiac asystole was ...
