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.
Thus, the CHA 2 DS 2-VASc score is a refinement of CHADS 2 [8] [10] score and extends the latter by including additional common stroke risk factors, that is, age 65–74, female gender and vascular disease. [11] In the CHA 2 DS 2-VASc score, 'age 75 and above' also has extra weight, with 2 points.
Reentry can produce single ectopic beats, or it can trigger paroxysmal tachycardia. Triggered beats are considered to be due to after-depolarizations triggered by the preceding action potential. These are often seen in patients with ventricular arrhythmias due to digoxin toxicity and reperfusion therapy after myocardial infarction (MI).
Since the premature beat initiates outside the sinoatrial node, the associated P wave appears different from those seen in normal sinus rhythm. Typically, the atrial impulse propagates normally through the atrioventricular node and into the cardiac ventricles, resulting in a normal, narrow QRS complex. However, if the atrial beat is premature ...
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system. Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis , and hyperthermia . [ 1 ]
Re-entry ventricular arrhythmia is a type of paroxysmal tachycardia occurring in the ventricle where the cause of the arrhythmia is due to the electric signal not completing the normal circuit, but rather an alternative circuit looping back upon itself. [1] There develops a self-perpetuating rapid and abnormal activation.
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 ]
Physical findings that should be evaluated include a comprehensive neurological examination for evaluation of stroke symptoms such as weakness, gait changes, slurred speech, and facial droop. [ 10 ] Additionally, if a paradoxical embolism is suspected in a patient, findings consistent with a congenital heart defect that may lead to right-to ...
