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]

Neurologic
- Dizziness
and alternating periods of bradycardia and atrial tachycardia, which is caused by sinoatrial node dysfunction A constellation of signs and symptoms which may include syncope, fatigue, dizziness, and alternating periods of bradycardia and atrial tachycardia [icd9data.com]
When your heart rhythm is too slow, this can cause dizziness, fatigue, feelings of lightheadedness, fainting or near-fainting spells. [uwhealth.org]
Vagally mediated AV block has a good prognosis from a mortality standpoint but may lead to dizziness and syncope. [itaca.edu.es]
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]
- Vertigo
The pathological nature and therapeutic response (pacemaker implantation) are therefore determined by the presence of symptoms that can vary in severity and specificity (syncope, lipothymia, asthenia, vertigo). [cardiocases.com]
Signs and symptoms [ edit ] The decreased heart rate can cause a decreased cardiac output resulting in symptoms such as lightheadedness, dizziness, hypotension, vertigo, and syncope. [en.wikipedia.org]
A sudden increase of ventricular rate during VT leads to the appearance of a sensation of feeling the heart beat (palpitations), dizziness, vertigo, signs of heart failure (shortness of breath or dyspnea), chest pain or chest tightness and unconsciousness [itaca.edu.es]
Persistent bradycardia is associated with symptoms such as fatigue, inability to concentrate, cognitive impairment, dizziness, shortness of breath or exercise intolerance, whereas intermittent bradycardia presents more often with vertigo, blurred vision [cardiovascmed.ch]
- Asthenia

- Meningism
We present the case of a previously healthy 2-year-old boy diagnosed with listeria meningitis. [ncbi.nlm.nih.gov]
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]
If further workup is done as an outpatient, 24- to 72-hour Holter monitoring can be used if the episodes occur somewhat frequently. If infrequent, an event recorder or ILR should be considered. [unboundmedicine.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]
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]
Treatment
This therapy was compared with Western medicine in the treatment of 24 cases. [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]
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]

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]

Epidemiology [ edit ] Sick sinus syndrome is a relatively uncommon syndrome in the young and middle-aged population. [en.wikipedia.org]
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]
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]
Pathophysiology
Although uncertain, the underlying pathophysiology likely reflects abnormal autonomic neural-cardiac inputs during REM sleep. [ncbi.nlm.nih.gov]

Prevention
CONCLUSIONS: Intravenous nicorandil reduces QT dispersion and prevents bradyarrhythmia during PTCA of the right coronary artery. [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]
