The proband was a 32-year-old woman who presented at age 26 years with palpitations, at which time electrocardiography (ECG) showed atrial fibrillation with a slow ventricular rate response. During periods of sinus rhythm, extremely low amplitude P-waves and prolonged atrioventricular (AV) conduction (first-degree AV block) were observed. ... In addition, 48-hour ambulatory heart rate monitoring showed profound sinus bradycardia with sinus rates as low as 33 beats per minute.
The patient's AF was refractory to antiarrhythmic medical management, but was eliminated after electrical isolation of the vein of Marshall; she remained in sinus rhythm and symptom free over a 2.5-year follow-up period.
Christophersen et al. (2013) studied a Scandinavian woman who had onset of palpitations at age 16 years and documented persistent atrial fibrillation by age 18. Electrocardiogram (ECG) showed sinus rhythm with severely prolonged PR interval (360 ms), incomplete right bundle branch block, and prolonged QTc (490 ms). ... Event recordings and an exercise test revealed intermittent supraventricular extrasystoles and sinus tachycardia, but atrial fibrillation was not documented, and a 12-lead ECG was normal.
The mother had onset of paroxysmal AF at 32 years of age, and required cardioversion 10 times over the next 14 years to return to normal sinus rhythm. She had a normal QTc, and her older daughter, who developed AF at 16 years of age, also had a normal QTc. ... Guerrier et al. (2013) reported a family in which the proband was a male infant with intermittent bradycardia, in whom ECG showed sinus bradycardia with normal intervals, including a QTc of 439 ms (upper limit of normal).
She was diagnosed at 58 years of age, and electrocardiogram (ECG) showed saddleback-type ST segment elevation in leads V1 to V3 that was present both during AF and during sinus rhythm, with beat-to-beat and day-to-day variability.
Description Atrial fibrillation is the most common sustained cardiac rhythm disturbance, affecting more than 2 million Americans, with an overall prevalence of 0.89%. The prevalence increases rapidly with age, to 2.3% between the ages of 40 and 60 years, and to 5.9% over the age of 65. The most dreaded complication is thromboembolic stroke (Brugada et al., 1997). For a discussion of genetic heterogeneity of atrial fibrillation, see 608583. Mapping Gudbjartsson et al. (2009) expanded the genomewide association study on atrial fibrillation in Iceland, which had identified risk variants on 4q25 (see 611494), and tested the most significant associations in samples from Iceland, Norway, and the United States.
Familial atrial fibrillation is an inherited abnormality of the heart's normal rhythm. Atrial fibrillation is characterized by episodes of uncoordinated electrical activity (fibrillation) in the heart's upper chambers (the atria), which cause a fast and irregular heartbeat. If untreated, this abnormal heart rhythm (arrhythmia) can lead to dizziness, chest pain, a sensation of fluttering or pounding in the chest (palpitations), shortness of breath, or fainting (syncope). Atrial fibrillation also increases the risk of stroke and sudden death. Complications of atrial fibrillation can occur at any age, although some people with this heart condition never experience any health problems associated with the disorder.
Echocardiogram was normal at 15 months of age, and medical treatment appeared to maintain the patient in sinus rhythm with a heart rate of 125 bpm; however, she died suddenly at 19 months of age.

Familial atrial fibrillation is an inherited heart condition that disrupts the heart's rhythm. It is characterized by erratic electrical activity in the heart's upper chambers (the atria), causing an irregular response in the heart's lower chambers (the ventricles). This causes a fast and irregular heartbeat ( arrhythmia ). Signs and symptoms may include dizziness, chest pain, palpitations , shortness of breath, or fainting. Affected people also have an increased risk of stroke and sudden death. While complications may occur at any age, some affected people never have associated health problems.

Variation in PR intervals has not been included in the diagnostic criteria because the PR interval varies with the length of the preceding RP interval. [4] Other diagnoses that may present with similar findings on electrocardiogram that should be included in the differential diagnosis include sinus tachycardia with frequent premature atrial contractions (this would have regular PP intervals), atrial flutter with variable AV node conduction (this would have regular PP intervals and flutter waves), atrial fibrillation (this would not have discrete P-wave morphologies), and wandering atrial pacemaker which would have a heart rate less than 100 beats per minute).

Multifocal atrial tachycardia is a rare supraventricular arrhythmia in neonates and young infants that is characterized by multiple P waves with varying P wave morphology and is usually asymptomatic. Epidemiology It is a very rare condition occurring in around 1 per 150,000 live births. Clinical description 'The disease mainly affects newborn infants (or those younger than 6 months of age) with a normal heart and no other underlying illness. Most infants are asymptomatic but some may show shortness of breath or respiratory distress. Less often, the disorder may occur in children with heart malformations (such as hypertrophic cardiomyopathy, tetralogy of Fallot, or atrioventricular canal defect; see these terms) or in those having recently undergone an open-heart surgery.
Atrioventricular canal was reported in 2 patients, 1 of whom was also diagnosed with cleft mitral valve, left superior vena cava to coronary sinus, and coarctation of the aorta, whereas the other was diagnosed with left pulmonary artery stenosis, hypoplastic left lung and pulmonary veins, as well as small secundum atrial septal defect (ASD) and trisomy 21. ...

An MR venogram is also performed in most cases to exclude the possibility of venous sinus stenosis/obstruction or cerebral venous sinus thrombosis . [5] [7] [8] A contrast-enhanced MRV (ATECO) scan has a high detection rate for abnormal transverse sinus stenoses. [10] These stenoses can be more adequately identified and assessed with catheter cerebral venography and manometry. [11] Buckling of the bilateral optic nerves with increased perineural fluid is also often noted on MRI imaging. ... They added the requirement that the person is awake and alert, as coma precludes adequate neurological assessment, and require exclusion of venous sinus thrombosis as an underlying cause. ... These may be used in severe papilledema, but otherwise their use is discouraged. [5] Venous sinus stenting [ edit ] Venous sinus stenoses leading to venous hypertension appear to play a significant part in relation to raised ICP , and stenting of a transverse sinus may resolve venous hypertension, leading to improved CSF resorption, decreased ICP, cure of papilledema and other symptoms of IIH.

Idiopathic intracranial hypertension (IIH) , formerly known as pseudotumor cerebri, is a condition that affects the brain. Pseudotumor cerebri literally translates to "false brain tumor." This term was used because symptoms of IIH resemble those of brain tumors depsite no tumor being present. Symptoms of IIH may include severe headache, nausea and vomiting, altered vision, and pulsating sounds within the head. A person with IIH may also have symptoms such as a stiff neck, back or arm pain, eye pain, and memory problems. If the condition remains untreated, permanent visual loss or blindness may develop.
Buchheit et al. (1969) described 2 sisters with idiopathic intracranial hypertension with papilledema (pseudotumor cerebri). Traviesa et al. (1976) described 3 affected sisters. The patients are typically young females who are obese and may be pregnant or suffering from chronic dysfunctional uterine bleeding. Johnston and Morgan (1991) described a mother and 2 of 4 daughters who had a diagnosis of pseudotumor cerebri and 1 son who developed communicating hydrocephalus. Warner et al. (2002) quantified vitamin A in the cerebrospinal fluid of patients with idiopathic intracranial hypertension, elevated intracranial pressure of other causes, and normal intracranial pressure. Vitamin A could be detected by high-pressure liquid chromatography in most of the specimens.
Idiopathic intracranial hypertension is a neurological disorder characterized by isolated increased intracranial pressure manifesting with recurrent and persistent headaches, nausea, vomiting, progressive and transient obstruction of the visual field, papilledema. Visual loss can be irreversible.
