  2. Sinus node dysfunction - Wikipedia

    en.wikipedia.org/wiki/Sinus_node_dysfunction

    Sinus node dysfunction (SND), also known as sick sinus syndrome (SSS), is a group of abnormal heart rhythms (arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. [1] [2] Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which the arrhythmia alternates between fast and slow heart ...

  3. Implantable cardioverter-defibrillator - Wikipedia

    en.wikipedia.org/wiki/Implantable_cardioverter...

    Congestive heart failure patients that were implanted with an ICD had an all-cause death risk 23% lower than placebo and an absolute decrease in mortality of 7.2 percentage points after five years in the overall population. 1 Reporting in 1999, the Antiarrhythmics Versus Implantable Defibrillators (AVID) trial consisted of 1,016 patients, and ...

  4. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Studies have shown that patients with Pacemaker syndrome and/or with sick sinus syndrome are at higher risk of developing fatal complications that calls for the patients to be carefully monitored in the ICU. Complications include atrial fibrillation, thrombo-embolic events, and heart failure. [7]

    normal sinus rhythm) to reverse the cardiomyopathy. [5] [9] The treatment of the tachyarrhythmia depends on the specific arrhythmia, but possible treatment modalities include rate control, rhythm control with antiarrhythmic agents and cardioversion, radiofrequency (RF) catheter ablation, or AV node ablation with permanent pacemaker implantation ...

  6. Inappropriate sinus tachycardia - Wikipedia

    en.wikipedia.org/wiki/Inappropriate_sinus...

    Inappropriate sinus tachycardia is a diagnosis of exclusion that is rarely made in an asymptomatic patient. [2] The following criteria are commonly used to define inappropriate sinus tachycardia: [10] The axis and morphology of the P wave during tachycardia similar to or identical to that experienced during sinus rhythm

  7. Sinus bradycardia - Wikipedia

    en.wikipedia.org/wiki/Sinus_bradycardia

    Sinus bradycardia is commonly seen in normal healthy persons and athletes in the absence of pathophysiological diseases or conditions. [1] Different factors or etiologies could lead to the dysfunction of the sinus node, causing a malformation or prolongation of the impulse. In terms of pathophysiological diseases, sinus rhythm may be caused by:

  8. Heart block - Wikipedia

    en.wikipedia.org/wiki/Heart_block

    In severe cases where the heart's ability to control and trigger heartbeats may be completely ineffective or unreliable, heart block can usually be treated by inserting an artificial pacemaker, a medical device that provides correct electrical impulses to trigger heart beats, compensating for the natural pacemaker's unreliability.

    en.wikipedia.org/wiki/ICD-10_Procedure_Coding_System

    The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
