Bradyarrhythmia


Presentation

  • Two case reports are presented of bradycardia in two elderly patients, which was resistant to atropine but which resolved immediately the acute bladder distension was treated.[ncbi.nlm.nih.gov]
  • Syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned.[ncbi.nlm.nih.gov]
  • We present the case of a previously healthy 2-year-old boy diagnosed with listeria meningitis.[ncbi.nlm.nih.gov]
  • We present a patient who experienced a dose-dependent, symptomatic sinus bradyarrhythmia with donepezil doses at and greater than 5 mg.[ncbi.nlm.nih.gov]
  • A 10-year-old boy is reported who presented with idiopathic atrial fibrillation and bradyarrhythmia. After history of intrauterine and postnatal bradycardia, atrial fibrillation was first documented electrocardiographically at 16 months of age.[ncbi.nlm.nih.gov]
Periodontitis
  • CONCLUSION: Specific periodontal bacterial infection might affect TA progression. KEYWORDS: Arrhythmia; Bacteria; Periodontal disease[ncbi.nlm.nih.gov]
  • Periodontitis affects arrhythmia It is well known that there is a relationship between periodontitis and CVD. However, there are few papers to show the association between arrhythmia and periodontitis.[bmccardiovascdisord.biomedcentral.com]
Heart Disease
  • An underlying structural heart disease was not evident. At the age of 10 years, implantation of a permanent ventricular demand pacemaker was indicated after syncope due to severe bradyarrhythmia.[ncbi.nlm.nih.gov]
  • Congenital heart disease : Congenital complete heart block may be an isolated lesion or may be associated with other types of congenital heart disease.[thoracickey.com]
  • We evaluated history of hypertension, diabetes mellitus, and ischemic heart disease, plasma NT-pro-BNP levels, body mass index (BMI), LVEF, left atrial diameter (LAD), and escape rhythm rate.[koreamed.org]
  • It can also be the consequence of surgery in congenital heart disease.[revespcardiol.org]
Slow Pulse
  • 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]

Skipped Beats
  • Symptoms When you have an arrhythmia, your heartbeat may be: Too slow (bradycardia) Too quick (tachycardia) Irregular, uneven, possibly with extra or skipped beats An arrhythmia may be present all of the time or it may come and go.[mountsinai.org]
  • beats or rapid or forceful beats), symptoms of hemodynamic compromise (eg, dyspnea, chest discomfort, presyncope, syncope), or cardiac arrest.[merck.com]
Dizziness
  • When your heart rhythm is too slow, this can cause dizziness, fatigue, feelings of lightheadedness, fainting or near-fainting spells.[uwhealth.org]

  • Diagnosis  Clinical ECG -syncope, fatigue, shortness of breath on exertion and dizziness. Severe bradycardia can cause haemodynamic consequences of hypotension, altered conscious state, poor perfusion, ischaemic chest pain and cardiac failure 7.[slideshare.net]
  • He complained of fatigue, dizziness, and heart palpitations, and an electrocardiogram (ECG) demonstrated sinus bradycardia at a rate of 39 bpm (the day of hospitalization; Figures 1A and 2A ).[dovepress.com]

Workup

  • Additional workup revealed TSH of Figure 1 c). Subsequent follow-up at 3 and 6 months revealed no change from the last EKG.[academic.oup.com]
  • He was admitted to our hospital for further workup. Despite discontinuation of metoprolol for 1 week, his telemetry revealed multiple episodes of sinus pause, observed during daytime sleepiness or snoring episodes.[jmedicalcasereports.biomedcentral.com]
  • If you have persistent symptoms despite medications, or an unclear diagnosis after an extensive workup for a symptomatic arrhythmia, your physician may refer you to a heart rhythm specialist for an electrophysiology study and possible catheter ablation[washingtonhra.com]

Treatment

  • This therapy was compared with Western medicine in the treatment of 24 cases.[ncbi.nlm.nih.gov]
  • The aim of the present study was to investigate the effects and risks of transplacental treatment for this condition.[ncbi.nlm.nih.gov]
  • Owing to underlying autonomic dysfunction, patients with DLB may be at increased risk of bradyarrhythmia resulting from treatment with acetylcholinesterase inhibitors.[ncbi.nlm.nih.gov]
  • Cardiac arrhythmia has been reported during lead tests performed during implantation of the device, but never during regular treatment.[ncbi.nlm.nih.gov]
  • Our patient presented a treatment challenge because he had significant sinus pauses associated with sleep apnea, but he refused recommended treatment.[jmedicalcasereports.biomedcentral.com]

Prognosis

  • A ventricular rate CONCLUSIONS: The prognosis of fetal bradyarrhythmia with CHD is still poor. The type of CHD, fetal myocardial dysfunction, and fetal hydrops were associated with a poor prognosis, depending on the ventricular rate.[ncbi.nlm.nih.gov]
  • Prognosis depends on the nature of the bradyarrhythmia and recognition of associated pathology such as cardiac structural defects, abnormal karyotype and degree of cardiac compromise.[ncbi.nlm.nih.gov]
  • We found that the type of CHD was strongly associated with prognosis.[jstage.jst.go.jp]

  • Prognosis of Atrioventricular Conduction Block The prognosis of patients with AV conduction disturbances depends on the site of the block, but also particularly on the concomitant or underlying heart disease.[revespcardiol.org]

Etiology

  • Alto Health Care System, Department of Medicine, Pulmonary, Critical Care and Sleep Medicine, 3801 Miranda Ave (111P), Palo Alto, CA 94304, USA. jholty@stanford.edu Abstract Cardiac arrhythmias during sleep are relatively common and include a diverse etiology[ncbi.nlm.nih.gov]
  • Firstly, these data cannot be extrapolated to young or middle-aged adults admitted due to iatrogenic bradycardia, as the underlying substrate and etiology may be different in this setting.[revportcardiol.org]
  • Clinically, a recent case-control study showed that high levels of periodontal clinical attachment loss, gingivitis and radiographic bone loss were independently associated with stroke, while the etiology of the stroke was not indicated [ 13 ].[bmccardiovascdisord.biomedcentral.com]

Epidemiology

  • The missing links are (1) clinical evidence of common factors shared by patients with ictal bradyarrhythmia and patients who die from SUDEP, (2) evidence of arrhythmia as a risk factor for SUDEP from epidemiological studies, and, (3) determination of[ncbi.nlm.nih.gov]

  • As some of the major epidemiological risk factors for QT prolongation and TdP, such as older age, female gender, heart failure, history of myocardial infarction and metabolic abnormalities, are also predictors of bradyarrhythmia in patients on antiarrhythmic[revportcardiol.org]
  • He has since completed further training in emergency medicine, clinical toxicology, clinical epidemiology and health professional education.[lifeinthefastlane.com]
  • 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]

Prevention

  • CONCLUSIONS: Intravenous nicorandil reduces QT dispersion and prevents bradyarrhythmia during PTCA of the right coronary artery.[ncbi.nlm.nih.gov]
  • Continuous positive airway pressure therapy prevented atrioventricular blocks that emerged after cardiac pacing for sick sinus syndrome. OSA could be associated with daytime bradyarrhythmia.[ncbi.nlm.nih.gov]
  • Permanent pacing clearly prevented Adam-Stokes attacks and showed beneficial effect on prevention of sudden death, and improvement of congestive heart failure or general morbidity. 4.[jstage.jst.go.jp]
  • This under-reporting equates to a lack of attention and earnest investigation into the cause, predisposition, and prevention of SUDEP.[books.google.com]
