Exercise induced paroxysmal artirioventricular block during nuclear perfusion stress testing: evidence of transient ischemia of the conduction system
However, 2 weeks later, the ECG still showed third-degree AV block, which indicated that recovery of the cardiac conduction system
Third, the asymmetric design might lead to mechanical imbalance, which in turn affects the septum and increases the risk of damage to the conduction system
While implantable cardiac devices can often effectively replace injured parts of your heart's electrical conduction system
, they carry their own sets of risks.
In each treatment two radiometers were installed above the plant, one of them positioned with the sensor facing upwards, measuring the incident solar radiation (global solar radiation, Sr) and another installed with the sensor facing downwards, measuring the reflected radiation (Rr ) by the crop in the central portion of each conduction system
It may be located in the main bundle or the distal conduction system
, but even longitudinal dissociation with asynchronous conduction in the bundle of His may give rise to abnormal patterns of activation within the bundle of His since specific fibers appear to be predestined to activate certain parts of the right and left ventricles.
These additional experiments are important because BPA may motivate conduction abnormalities in individuals with preexisting heart conditions, such as AV conduction dysfunction, disease of the cardiac electrical conduction system
, or fibrosis of the atria and/or ventricles.
The electrophysiologic effect of volatile anaesthetics and sufentanil on the normal atrioventricular conduction system
and accessory pathways in Wolff Parkinson White syndrome.
After a heart attack, the occurrence of multiple ectopic beats is a sign of damage to the heart muscle's conduction system
While the structure of the human heart has been known for a long time, the evolutionary origin of our conduction system
has nevertheless remained a mystery.
Electrophysiologic delineation of specialized A-V conduction system
in patients with corrected transposition of the great vessels and ventricular septal defect.
Although histological studies were not performed, it is possible that our patient could have minor abnormalities of the cardiac conduction system
that predated her chloroquine treatment.
