The longterm effects of pacemaker therapy have been investigated in 337 patients with bradycardia and congestive heart failure with or without Adams-Stokes syncope. The cumulative survival rate in patients with Adams-Stokes seizures without congestive heart failure (group I) is markedly better than in patients with Adams-Stokes seizures and congestive heart failure (group II). The death rate is highest in patients with congestive heart failure as sole indication for pacemaker implantation (Group III). In the patients from group II (mainly with slight to moderate decompensation) there was a higher percentage of improvement than in those from group III (chiefly with severe congestive heart failure), in whom cardiac decompensation improved in approximately half the cases. These findings do not prompt excessive enthusiasm about the longterm results in patients with bradycardia and severe congestive heart failure. The indication subsists where there is resistance to drug therapy, or digitalis intolerance, or where treatment with a provisional pacemaker produces good results.

Eleven men with disabling reactive hypoglycemia, in a range of 12 to 50 mg per 100 ml, were treated an average of seven years after gastric surgery with a 10 cm reversed jejunal segment. The reversal was placed at the gastric outlet in six patients and just below the ligament of Treitz in five. The former technic produced a somewhat better correction of hypoglycemia than did the latter. A good result was obtained in all eleven and none has had recurrence of seizures or fainting. Whereas the average minimal blood sugar before reversal was 34 mg per 100 ml, after reversal it was increased to 64 mg per 100 ml. The most severe hypoglycemia was noted in a patient after vagotomy and pyloroplasty. We recommend that all patients with dumping syndrome undergo glucose tolerance tests and plasma insulin determinations to ascertain whether they have reactive hypoglycemia. It is our conclusion that introduction of a reversed jejunal segment can control refractory reactive hypoglycemia resulting from previous gastric surgery.

We studied the diagnostic interpretation by physicians of written histories of 118 patients with a transient loss of consciousness. Considerable disagreement about a diagnosis of either syncope or seizure was found. Overall agreement was only 31%; an erroneous diagnosis was made in 16% of cases. We concluded that the diagnosis of a seizure after a single event is often too unreliable to justify early treatment.

In a group of female in-patients clinically diagnosed as having non-epileptic attack disorder there was an increased incidence of a proven previous history of sexual abuse in childhood, when compared with a group of women with epilepsy and a group of women with other psychiatric disorders admitted to the same ward. This was particularly true of women with the 'swoon' and 'abreactive' type of non-epileptic attack disorder (see Part I). The incidence of a history of previous abuse was similar to the two control groups for other types of non-epileptic attack disorder. The swoon was seen as a cut-off phenomenon: the abreactive attack as a kind of acting out the memory of the abuse, part of a post-traumatic stress disorder. Both may respond to counselling for the abuse although it is too early to be certain, and there is a risk of further episodes of the non-epileptic attack disorder during periods of stress. Some patients with epilepsy, however, also had a history of previous sexual abuse: in some the stress of the abuse may have precipitated the epileptic seizures.

To determine the factors relating to prognosis, the records of 15 neonates with persistent prolongation of the QT interval on the electrocardiogram after the fourth day of life were reviewed. Patients were admitted for symptoms (syncope, cardiac failure, or seizures), abnormal auscultation with an irregular heart rate or bradycardia, or because of a family history of a long QT syndrome. All infants had a long QTc, ranging from 0.46 to more than 0.70 second. Eight patients who had a QTc over 0.60 second developed severe ventricular arrhythmias (torsades de pointes, ventricular tachycardia) or second-degree AV block. Twelve of 15 were treated with beta-blocking agents, combined with ventricular pacing in five cases. Four infants died in the first month of life; they all had a very long QT interval and had experienced ventricular arrhythmias and AV block. Six children are still being treated with beta-blocking agents for the long QT syndrome and are doing well. In five infants, electrocardiographic abnormalities were transient and the QT interval returned to normal within 1 year. Therefore (1) prolongation of the QT interval in neonates may be transient or may represent an early form of the long QT syndrome and (2) the length of the QT interval may provide data on prognosis: those with a QTc less than 0.50 second returned to normal; those with a QTc greater than 0.60 second were associated with severe arrhythmias and four of eight infants died.

Each time he stood up a 60-year old man experienced myoclonic jerks, quickly followed by a syncope due to major postural hypotension. Progressive autonomic failure was associated with pyramidal, extrapyramidal and cerebellar features in a pattern characteristic of Shy-Drager disease. Myoclonic jerks suggested seizures, but no electroencephalographic epileptiform activity was found. This case together with data from the literature suggest, that such involuntary movements may result from cerebral anoxia.

A rare case of neurosarcoidosis presenting with psychomotor seizure is reported. A 35-year-old woman was admitted to our ward for further evaluation of syncopal attacks and suspected sarcoidosis. The patient had a history of syncopal attacks for about 15 years prior to admission; however, the pathogenesis was not clarified in spite of various examinations. Three months prior to admission, left peripheral facial nerve palsy, bilateral hypopion and bilateral hilar lymphadenopathy on plain chest film were noted at the departments of neurosurgery and ophthalmology of our hospital. She was referred and admitted to our ward. The diagnosis of sarcoidosis was made by scalene node biopsy. The syncopal attacks could not be controlled by several anticonvulsant agents. Although no significant findings were observed on brain CT and cerebral angiography, spike wave was revealed on electroencephalography (EEG) in the parieto-temporal lead. The syncopal attacks were diagnosed psychomotor seizures from both the clinical features and the EEG findings. We concluded that syncope was caused by neurosarcoidosis. The patient was prescribed steroid with much improvement of these symptoms.

In 24 patients with diagnostically not clear, short, recurrent episodes of consciousness disturbances and heart diseases and/or a history of arrhythmia simultaneous 24-hour recording was done of eeg and ecg. In the differential diagnosis epilepsy was considered, especially since in most cases routine eeg records demonstrated slight episodic changes. During 24-hour recording in 8 cases typical episodes of consciousness disturbances developed but in none of them these episodes were associated with arrhythmia which ruled out their cardiogenic origin. In 2 cases EEG recording served for establishing the diagnosis of partial complex seizures, 2 patients had hyperventilation syncope, one had TIA, in the remaining 3 cases absence of eeg and ecg changes during these episodes and coexistence of anxiety neurosis suggested functional origin. So the combined 24-hour eeg+ecg recording made possible establishing of diagnosis in 1/3 of these patients, enabling adequate treatment to be instituted.

Seven out of 829 pediatric cardiac patients (0.84%) were found to have sinus node dysfunction (SND) over the past seven years. Of the seven patients, three had structurally normal hearts. One of these three patients had long QT syndrome. In four patients, structural heart disease was noted. In three of these four patients the sinus node dysfunction was attributed to cardiac surgery. The age of onset of SND ranged from four months to eight years. Presenting symptoms and signs included syncope, near-syncope, seizure and congestive heart failure. Two patients were asymptomatic. Five patients had episodic sinus pause. Sinus or junctional bradycardia was noted in four patients. Three had tachy-bradycardia. High grade atrioventricular block was noted in one patient. Treadmill exercise test revealed a nonsustained ventricular tachycardia in two patients. All seven patients were found to have prolonged maximal corrected sinus node recovery time. Prolonged intra-atrial conduction time was found in three, prolonged AV nodal conduction time in one, and prolonged His-Purkinje conduction time in one patient during the electrophysiologic study. All seven patients showed abnormal results in intrinsic heart rate study. Anti-arrhythmic drugs were prescribed. During the follow-up study, no patient died, but two patients received a pacemaker implantation. Because of the extent of their conduction system diseases, it is recommended that patients with SND should be thoroughly investigated.

A 33 year-old-man presented recurrent syncopal episodes after venipuncture. This was sometimes associated with seizure. It was also noted that the syncope was aroused by mental stress. The patient was admitted to the department of neurological medicine because of epilepsy. Cardiac arrest of more than 15 seconds was detected during the venipuncture-prooshed syncope test. He had normal routine testing, holter monitoring, head CT scan, carotid sinus massage, valsalva maneuver etc. The syncope was similar to a malignant vasovagal one which has no typical warning signs. He had recurrent syncopal episodes without typical prodrome. Therefore a DDD pacemaker was implanted. It has not been completely established as effective in the treatment of vasovagal syncope, but for the treatment of syncope involving cardioinhibitory action, dual chamber pacing in considered as the main treatment available.
