Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
This is an incomplete list, which may never be able to satisfy certain standards for completion.. There are many conditions of or affecting the human circulatory system — the biological system that includes the pumping and channeling of blood to and from the body and lungs with heart, blood and blood vessels.
This person was eventually diagnosed with tachycardia-induced cardiomyopathy. [7] There are no specific diagnostic criteria for TIC, and it can be difficult to diagnose for a number of reasons. First, in patients presenting with both tachycardia and cardiomyopathy, it can be difficult to distinguish which is the causative agent. [5]
The management of tachycardia depends on its type (wide complex versus narrow complex), whether or not the person is stable or unstable, and whether the instability is due to the tachycardia. [10] Unstable means that either important organ functions are affected or cardiac arrest is about to occur. [ 10 ]
A rapid, regular heartbeat is usually due to paroxysmal SVT or ventricular tachycardia. [1] A rapid, irregular rhythm might be due to atrial fibrillation, atrial flutter, or tachycardia with a variable block. [1] Supraventricular and ventricular tachycardias often cause sudden palpitations, beginning and ending rapidly.
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
Chest pain with features characteristic of cardiac origin (angina) can also be precipitated by profound anemia, brady-or tachycardia (excessively slow or rapid heart rate), low or high blood pressure, severe aortic valve stenosis (narrowing of the valve at the beginning of the aorta), pulmonary artery hypertension and a number of other conditions.
