We present a 2-year-old girl with trisomy 21 who developed the rapid onset of bradycardia during anesthetic induction with sevoflurane. Previous reports are reviewed, postulated mechanisms discussed, and preventative strategies presented. [ncbi.nlm.nih.gov]

When a P wave is present and not followed by a QRS wave (and heart contraction), there is an atrioventricular block, and a very slow pulse (bradycardia). [mountsinai.org]

The treatment sequence is determined by the severity of the patient's clinical presentation. If perfusion is adequate, monitor and observe the patient. [acls.net]

Subsequent cardiac workup showed no abnormalities. We believe the cause of arrest was sugammadex, considering the time of administration, the absence of cardiac disease, and stable operative course. [ncbi.nlm.nih.gov]

Serologic titers for various infectious diseases such as Lyme disease may be helpful in a short-term capacity, but since the results will not be available immediately, they are not essential in the initial diagnostic workup. [reliasmedia.com]

• Absent A-Waves

  In third-degree, or complete, SA block, the surface ECG is identical to that of sinus arrest, with absent P waves. [emedicine.com]

  ECG typically shows absent P waves with escape rhythm: Junctional - narrow complexes at 45-60 bpm. Ventricular - wide complexes at 30-45 bpm. Usual causes: Ischaemia. Hyperkalaemia. Excess vagal tone. Negative chronotropes. Treat if symptomatic. [patient.info]

Learn how it's diagnosed, and what treatments can help. Treatments Treatment for bradycardia depends on what is causing it and the severity of your symptoms. The goal of treatment is to raise your heart rate so your body gets the blood it needs. [vidanthealth.com]

Bradycardia Treatment Bradycardia treatment depends on your test results. Your doctor at the UPMC Heart and Vascular Institute's Cardiac Electrophysiology Program will go over your test results and discuss treatment options. [upmc.com]

Treatment When an arrhythmia is serious, you may need urgent treatment to restore a normal rhythm. [mountsinai.org]

Treatment. It rarely requires treatment unless it causes symptoms. Then, a pacemaker may be implanted if there is no cause that can be easily treated. [cigna.com]

Treatments Treatment for bradycardia varies from person to person and depends upon the severity, frequency and cause of the slower heart rate. Treatment for a slow heartbeat is a pacemaker. [wexnermedical.osu.edu]

BACKGROUND: The prognosis of super-elderly patients (age≥85 years) who undergo bradycardia pacemaker (PM) implantation remains unknown. [ncbi.nlm.nih.gov]

The lower the fetal heart rate, the worse the prognosis. [radiopaedia.org]

Bradycardia can also be produced by drugs such as digitalis or morphine and is a common abnormality in heart attack victims, for whom it often indicates a favourable prognosis. [britannica.com]

Prognosis Prognosis varies depending on what’s causing bradycardia. Some conditions can be reversed or managed through medication, lifestyle changes and regular monitoring. Others may require a pacemaker or implantable cardioverter defibrillator. [baptisthealth.com]

Prognosis for bradycardia resulting from extrinsic influences on the heart largely depends upon the underlying diagnosis. [accessmedicine.mhmedical.com]

Etiology Sinus bradycardia has many intrinsic and extrinsic etiologies[5]][6][7][8][9][10]. [ncbi.nlm.nih.gov]

Consider this diagnosis in patients without other etiologies of conduction disorders. [reliasmedia.com]

He has since completed further training in emergency medicine, clinical toxicology, clinical epidemiology and health professional education. [lifeinthefastlane.com]

One in 600 adults over the age of 65 has sinus node dysfunction, but more research needs to be done to collect epidemiologic data within the United States and globally for patients with sinus bradycardia.[11] Pathophysiology Sinus bradycardia as any of [ncbi.nlm.nih.gov]

Epidemiology It is impossible to give meaningful figures on incidence and prevalence. In most young people bradycardia is physiological and represents athletic training. [patient.info]

[…] epinephrine) or transcutaneous pacing should be used.[13] Transvenous pacing may be required if the cause of the bradycardia is not rapidly reversible.[13] In children, giving oxygen, supporting their breathing, and chest compressions are recommended.[14][15] Epidemiology [en.wikipedia.org]

This case report highlights the occurrence of this complication during a routine removal of a true vocal fold lesion at a tertiary medical center and discusses the potential pathophysiological mechanisms and proposed management options for this phenomenon [ncbi.nlm.nih.gov]

The pathophysiology of sinus bradycardia is dependent on the underlying cause. [1] Commonly, sinus bradycardia is an incidental finding in otherwise healthy individuals, particularly in young adults, athletes or sleeping patients. [2] Other causes of [emedicine.com]

Causes of pathophysiologic sinus bradycardia include: Advanced age Problems with the SA node (sick sinus syndrome) Inflammatory heart conditions, like pericarditis or myocarditis Heart conditions that exist at birth (congenital) Increased pressure inside [saintlukeskc.org]

Prevention Taking steps to prevent coronary artery disease may reduce your chance of developing an arrhythmia. [mountsinai.org]

Highly trained athletes may also have athletic heart syndrome, a very slow resting heart rate that occurs as a sport adaptation and helps prevent tachycardia during training. [dbpedia.org]

Treatment may include a pacemaker to prevent the heart from beating too slowly. Medicines might be used to prevent the heart from beating too fast. Blood-thinning medicines might be used to help prevent a stroke. [cigna.com]

Bradycardia prevention Bradycardia can’t always be prevented. You may help prevent bradycardia by lowering your risk of heart disease. [healthdirect.gov.au]
