1/856. syncope two years after hysterectomy.

    A 61-year-old woman presented to the emergency department after experiencing palpitations, shortness of breath, and syncope while taking a shower. Her husband revived her with mouth-to-mouth resuscitation. She had had a similar episode three days earlier while making her bed and had lost consciousness for about 10 sec. She did not appear to have had a seizure. Five months earlier, while taking a walk, she had experienced dizziness, dyspnea, and chest pressure lasting about an hour. A workup at that time included cardiac catheterization, lung scanning, and esophagogastroduodenoscopy, but no abnormality was found. lower extremity edema was noted. ( info)

2/856. Neurally mediated syncope in 2 patients with extracardiac disease.

    We describe the cases of 2 patients with repetitive episodes of syncope with profound bradycardia and hypotension. In both patients, the symptoms were initially thought to be neurally mediated and idiopathic but were ultimately determined to be triggered by serious underlying pathologic processes: a massive and locally invasive tumor of the hypopharynx in 1 patient and a gangrenous gallbladder in the other. Appropriate treatment resulted in a resolution of this syndrome in both patients. These cases emphasize the importance of an appropriate evaluation and broad differential diagnoses for patients with severe bradycardia and hypotension. ( info)

3/856. Cardiac syncope secondary to glossopharyngeal neuralgia--effectively treated with carbamazepine.

    A 64-year-old male with glossopharyngeal neuralgia, cardiac asystole and grand mal seizures has been relieved of his attacks by intake of 400 mg of carbamazepine per day over a 4-year period. Simultaneous EEG-EKG recordings before and after drinking water document the diagnosis. ( info)

4/856. syncope in the pediatric patient. The cardiologist's perspective.

    The evaluation of syncopal children or adolescents relies heavily on a thorough, detailed history and physical examination. All syncope associated with exercise or exertion must be considered dangerous. The ECG is mandatory, but other laboratory tests are generally of limited value unless guided by pertinent positives or negatives in the history and physical examination. The ECG allows screening for dysrhythmias, such as wolff-parkinson-white syndrome, heart block, and long qt syndrome, as well as hypertrophic cardiomyopathies and myocarditis. Tilt table testing can be useful in selecting therapy by demonstrating the physiologic response leading to syncope in an individual patient. The most common type of syncope in otherwise healthy children and adolescents is neurocardiogenic or vasodepressor syncope, which is a benign and transient condition. Because syncope can be a predictor of sudden cardiac death, it must be taken seriously, and appropriate screening must be performed. ( info)

5/856. hypokalemia with syncope caused by habitual drinking of oolong tea.

    A 61-year-old woman developed hypokalemia, atrioventricular block and ventricular tachycardia with syncope after habitual drinking 2 to 3 liters of oolong tea per day. She had been suffering from rheumatoid arthritis and sjogren's syndrome and her serum albumin was decreased (2.9 g/dl). Oolong tea contains caffeine at approximately 20 mg/dl. Great quantities of caffeine can induce hypokalemia. The serum protein binding caffeine is albumin. Accordingly, in patients with hypoalbuminemia, caffeine is apt to induce hypokalemia. This case suggested that great quantities of oolong tea, one of the so-called "healthy" drinks, result in serious symptoms for patients with hypoalbuminemia. ( info)

6/856. back pain and collapse associated with receding subarachnoid blockade.

    PURPOSE: back pain and sudden loss of consciousness during recovery from spinal anesthesia are rare. Severe pain may raise fears of serious neurological damage and result in inappropriate management. Bladder distention may present in this way and clinicians should be alert to this possibility and communicate this to nursing staff. CLINICAL FEATURES: A lumbar spinal anesthetic was performed during a volunteer study, using 15 mg hyperbaric bupivacaine in a healthy 31 yr old man. During recovery, five hours later, as the block regressed to the L1-2 level, he complained of acute, severe back pain and briefly lost consciousness secondary to profound bradycardia. Bladder cathetherization yielded 900 mL urine with immediate and complete relief of symptoms. CONCLUSION: Severe pain secondary to bladder overdistention in the presence of neuroaxial blockade may be referred to the thoracolumbar area, mediated by intact sympathetic afferents. As the saccral parasympathetic supply remains paralyzed, there is no subjective sensation of bladder stretching. If untreated, bladder distention can lead to excessive supraspinal parasympathetic outflow resulting in vasovagal syncope. ( info)

7/856. Convulsive syncope following placement of sphenoidal electrodes.

    Two cases of convulsive syncope following the insertion of sphenoidal electrodes are reported. The episodes occurred shortly after an uneventful insertion of the needle. Both patients exhibited behavioral arrest with loss of muscle tone, followed by flexor posturing, jerking of the extremities, then followed by what appeared to be a panic attack. Episodes were clinically distinct from the patients' typical spells and were initially interpreted as representing psychogenic events. EEGs during the episodes showed diffuse slowing followed by generalized suppression of rhythms. Simultaneous EKG showed bradycardia followed by brief asystole and then resumption of normal heart rhythms in both cases. Vagally mediated cardioinhibitory reactions induced by fear, pain and possibly stimulation of branches of the trigeminal nerve in the face represent an uncommon but potentially serious complication of placement of sphenoidal electrodes.

8/856. Metastatic germ cell tumor to the heart presenting with syncope.

    Malignant nonseminomatous germ cell tumors (NSGCT) rarely metastasize to the heart. The first such case presenting with syncope is described. Eight previously described cases of NSGCT with intracaval metastasis to the heart are reviewed and the literature to date is discussed. Transesophageal echocardiography is the diagnostic study of choice and treatment consists primarily of platinum-based chemotherapy followed by surgical resection of residual deposits. ( info)

9/856. A case of vasospastic angina presenting Brugada-type ECG abnormalities.

    An electrophysiological study and a provocative test of coronary artery spasm was attempted in a 68-year-old man who was having syncopal attacks and chest pain. His electrocardiogram had the characteristics of brugada syndrome and ventricular fibrillation (VF) was induced by programmed electrical stimulation. ST-segment elevation became exaggerated by procainamide, which could not prevent the induction of VF. coronary angiography revealed no stenotic lesions, and spasm in the left coronary artery was induced by intracoronary administration of acetylcholine with similar chest pain to that experienced before. Under treatment with diltiazem and flecainide, which suppressed the induction of VF, the patient experienced no recurrence of symptoms despite persistent ST-segment elevation. No previous reports have described coronary spasm associated with Brugada-type ECG abnormalities, and patients with syncope should be evaluated carefully. ( info)

10/856. andersen syndrome autosomal dominant in three generations.

    andersen syndrome is a rare entity and comprises potassium sensitive periodic paralysis, ventricular arrhythmia, and an unusual facial appearance; syncope and sudden death have also been reported. The recognition of the characteristic face permits an early diagnosis in order to detect the severe systemic manifestations that are associated with this syndrome. The genetic defect is not linked to any other form of potassium sensitive periodic paralysis nor is it related to that of the long qt syndrome; nevertheless, a prolonged QT interval can be detected in a significant proportion of the cases. Sixteen cases of this syndrome have been described. We report on a three-generation family with 10 affected members. To our knowledge, this is the largest number of cases reported in one family. We noted some additional minor anomalies such as broad forehead and malar hypoplasia. Our patients had variable expression in the classical triad and of the severity of the systemic manifestations. Five of 8 affected studied members did not have a long QTc, which has been suggested as a constant finding in this syndrome. ( info)
