A nabothian cyst (or nabothian follicle) [1] is a mucus-filled cyst on the surface of the cervix. They are most often caused when stratified squamous epithelium of the ectocervix (portion nearest to the vagina) grows over the simple columnar epithelium of the endocervix (portion nearest to the uterus). This tissue growth can block the cervical ...
Paroxysmal tachycardia is a form of tachycardia which begins and ends in an acute (or paroxysmal) manner. It is also known as Bouveret-Hoffmann syndrome. [ 1 ] [ 2 ] [ 3 ]
Generally, diseases outlined within the ICD-10 codes G40-G47 within Chapter VI: Diseases of the nervous system should be included in this category. Subcategories This category has the following 4 subcategories, out of 4 total.
For TIC due to atrial fibrillation, rate control, rhythm control, and RF catheter ablation can be effective to control the tachyarrhythmia and improve left ventricular systolic function. [ 5 ] [ 9 ] For TIC due to atrial flutter, rate control is often difficult to achieve, and RF catheter ablation has a relatively high success rate with a low ...
Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. [1] This is different from normal pacemaking activity, where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm. Causes of wandering atrial ...
Lead II of electrocardiogram shows 3 rapid heartbeats, supraventricualar extrasistoles due to atrioventricular nodal reentry, shown as red, demonstrating unexplained onset and stop of the episode in paroxysmal supraventricular tachycardia among normal heart rhythm shown as blue. Paroxysmal supraventricular tachycardia is a type of arrhythmia ...
In-between episodes there is normal electrical conduction in the heart. During an episode of AVRT caused by PJRT, the accessory pathway conducts electrical activity from the ventricles directly back to the atria at the end of systole, which triggers the atria to contract, and the current to pass back to the ventricles again via the atrioventricular node (AV node); see diagram.
An automatic tachycardia is a cardiac arrhythmia which involves an area of the heart generating an abnormally fast rhythm, sometimes also called enhanced automaticity.These tachycardias, or fast heart rhythms, differ from reentrant tachycardias (AVRT and AVNRT) in which there is an abnormal electrical pathway which gives rise to the pathology.
