Two groups of unanesthetized dogs, each consisting of six animals with ventricular tachycardia caused by two-stage ligation of the anterior descending branch of the left coronary artery on the day before treatment, were given continuous intravenous infusions of 0.5 mg/kg/min of either droxicainide [DL-N-(2-hydroxyethyl) pipecolinyl-2,6-dimethylanilide] hydrochloride or lidocaine hydrochloride until convulsions occurred. At low cumulative doses of either drug, the infusions produced a progressive reduction in the frequency of ventricular ectopic beats, but no significant changes in the sinus rate, the PR or QRS intervals of normal sinus beats, the arterial and central venous pressures, or the respiratory rate. At higher cumulative doses lidocaine produced sedation, and both drugs produced
emesis
and then convulsions that subsided soon after termination of treatment. With respect to both the cumulative doses and plasma concentrations at which they reduced the frequency of ectopic beats by 25, 50, and 75% and at which they produced convulsions, droxicainide was a more potent antiarrhythmic agent than lidocaine and had a wider margin of safety.

Ergonovine administration during coronary angiography is frequently used to rule out coronary spasm as a cause of chest pain. We performed this study to determine which electrocardiographic variables (other than ST segment elevation with pain) and which chest pain characteristics might be predictive of ergonovine test outcome in patients without obstructive coronary disease. Thirty-one patients had an electrocardiogram recorded during chest pain. Three of four patients (75%) who had an ischemic electrocardiogram with pain had a positive ergonovine test while only 1 of 27 (4%) patients who had a nonischemic electrocardiogram during chest pain had a positive ergonovine test (p less than 0.001) Pain that occurred predominantly at rest was present in five of five patients with positive ergonovine tests but pain occurring predominantly at rest was also present in 76% of patients with negative ergonovine tests (85%). Prompt relief of pain with nitroglycerine was also present in all patients with a positive ergonovine test but was also seen in 58% of patients with a negative test (NS). Association of chest pain with nausea,
vomiting
, diaphoresis, or radiation to left arm, jaw or neck were similarly poor predictors of ergonovine test outcome. We conclude that ergonovine testing in patients without obstructive coronary disease is of low yield if an electrocardiogram recorded during pain does not show evidence of ischemia. Historical features of the chest pain are not good predictors of test outcome.

Total fundoplication gastroplasty was designed to combine the low anatomic recurrence rate of gastroplasty with the effectiveness of reflux control obtained by total wrap. The problems requiring evaluation are anatomic recurrence, continued reflux, dysphagia, inability to belch or vomit, and gas bloat, all of which have been described in procedures employing a total wrap. Five hundred consecutive patients were analyzed 6 to 60 months following operation. There were no deaths and a 3.6% incidence of short-term operative morbidity. Follow-up was available clinically in 98.4% (495 patients), radiologically in 89.6% (448), and manometrically in 69.5% (347). Two patients have anatomic recurrence (0.4%) and none has reflux. Excellent results occurred in 93.4% (467), improvement in 5% (25), and poor results in 1.6% (eight). Repeat operation was necessary in 0.4% (two) for recurrence and in 0.8% (four) for severe dysphagia. The other problems were minor dysphagia in 2.2% (11), gastritis in 1.2% (six), late cholelithiasis in 0.4% (two), and continued pain with poor results in 0.4% (two). The length of the gastroplasty tube and the subdiaphragmatic position of the high-pressure zone (HPZ) did not affect the result of the operation. A long tube and unwrapped supradiaphragmatic HPZ was present in 18.8% (94); none had reflux or major dysphagia. Total length of the gastroplasty wrap was 3 to 4 cm in the first 200 and the incidence of major dysphagia was 5% (10). Reducing the length of fundoplication to 1.5 to 2 cm reduced the incidence of dysphagia to 1.7% (five). Other problems of gastritis and difficulty with belching and
vomiting
occurred in a random fashion. This procedure is effective in reflux control, prevents anatomic recurrence and, if the completed fundoplication is maintained at 1.5 to 2 cm, yields a low incidence of significant dysphagia.

Between January 1, 1980, and December 31, 1990, 147 patients (93 female and 54 male) were found to have an intrathoracic stomach. Median age was 69 years (range 34 to 89). Signs and symptoms occurred in 140 patients (95.2%) and were primarily obstructive. They included postprandial pain in 87 (59.2%),
vomiting
in 46 (31.3%), and dysphagia in 44 (29.9%); only 23 patients (15.7%) had symptoms of gastroesophageal reflux. Anemia was present in 31 patients (21.1%) and melena in 3. Elective repair was done in 119 patients and included an uncut Collis-Nissen repair in 81 patients (68.1%), a Belsey Mark IV repair in 19 (16.0%), a Nissen repair in 17 (14.3%), and a Harrington (anatomic) repair in 2 (1.7%). Thirty-two patients had complications (26.9%). There were no operative deaths. Median follow-up was 42 months. Results were excellent in 69 patients (60.0%), good in 38 (33.0%), fair in 6 (5.2%), and poor in 2 (1.7%). Five patients had emergency operations for suspected strangulation; three had gastric necrosis, and one died. Two of the four operative survivors had excellent results. Twenty-three other patients were followed up with medical management for a median of 78 months (range 12 to 268 months). In four patients progressive symptoms developed, and one patient died from aspiration. We conclude that patients with an intrathoracic upside-down stomach who have obstructive symptoms at initial presentation should undergo repair and that elective operation is safe and effective. Gastric strangulation, however, is rare.

We experienced a case of spontaneous rupture of the esophagus after gastrointestinal examination using barium. A 48-year-old male experienced severe chest pain after
vomiting
following gastrointestinal examination. Chest X-ray revealed a right pneumothorax and pleural effusion by barium. We diagnosed spontaneous rupture of the esophagus and performed right thoracotomy 6 hours after onset of symptoms. At 10 cm above the diaphragm, there was a vertical perforation 3 cm in length. Following saline lavage, the ruptured esophageal wall was directly closed by the layer to layer method. The post operative course was uneventful and the patient was discharged 3 weeks after surgery. Cases of spontaneous rupture of the esophagus into the right thoracic cavity induced by gastrointestinal examination are extremely rare.

Boerhaave's syndrome (spontaneous esophageal perforation) is an uncommon clinical entity that frequently presents with an antecedent history of marked
vomiting
followed by chest or abdominal pain. We report a case of spontaneous rupture of the esophagus in 53-year-old male who was referred to our hospital with a chest discomfort. A chest radiogram revealed pleural effusion and pneumomediastinum. Nine hours after onset, the diagnosis of Boerhaave's syndrome become evident. She underwent operative repair and, after a prolonged stay, was discharged in relatively good condition 55 days after admission. The absence of
vomiting
prior to presentation is the distinguishing feature of this particular case. This is the seventh case in the English literature to our knowledge.

BACKGROUND: The electrophysiologic and antifibrillatory properties of tedisamil (KC-8857;3,7-di-(cyclopropylmethyl)-9,9-tetramethylene-3,7-diazabicyclo[3.3.1]-nonane dihydrochloride) were studied in a conscious canine model of sudden cardiac death. METHODS AND RESULTS: Three to five days after surgically induced myocardial infarction (2-hour occlusion of the left anterior descending coronary artery), animals were subjected to programmed electrical stimulation to identify those at risk for ischemia-induced ventricular fibrillation. Sixty minutes after tedisamil (10 mg/kg, administered orally) PES was repeated. Tedisamil increased the ventricular effective refractory period from 106 +/- 6 to 134 +/- 7 ms (P <.05) compared to placebo treatment, which did not alter the ERP (123 +/- 6 to 116 +/- 5 ms). Tedisamil prolonged the QTc interval, from a predrug value of 308 +/- 14 to 327 +/- 14 ms, postdrug. The extent of the surgically induced anterior wall myocardial infarct did not differ between groups, tedisamil, 29 +/- 2%, and placebo, 28 +/- 2% of the left ventricle. CONCLUSIONS: Tedisamil conferred protection against ischemia induced ventricular fibrillation; 7 of 10 tedisamil-treated dogs survived, compared to 4 of 14 surviving in the vehicle treated group (P <.05). Although we observed instances of
vomiting
and/or diarrhea in several dogs after a single oral administration of tedisamil, the data indicate that oral administration of tedisamil provides protection from ischemia-induced ventricular fibrillation in the postinfarcted conscious canine. The mechanism by which tedisamil achieves its antifibrillatory effect may be related to its ability to prolong the ERP of the ventricular myocardium without altering ventricular conduction velocity.

A 75-year-old female, exhibiting epigastric pain and
vomiting
, underwent treatment for acute gastritis. She also experienced incontinence of urine and chest pain. A diagnosis of acute myocardial infarction was made upon examination of electrocardiographic findings and the patient was transferred to our hospital. Diffuse infarction of the left ventricle and acute aortic dissection (Stanford type A) were diagnosed by electrocardiographic and echo-cardiography. An emergency operation was performed. After induction of anesthesia, elevation of pulmonary artery pressure and fall of pulse pressure were observed, indicating acute cardiac tamponade. Transesophageal ultrasonography disclosed the entry of dissection in the descending aorta. Dissection of the aorta extended proximally up to the annulus of the aortic valve and the right and left coronary arteries were compressed by its aneurysm. As aortic insufficiency was mild, only reconstruction of the ascending aorta was carried out. The patient was discharged in fair condition one month after operation under use of postoperative long-term administration of catecholamines.

Spontaneous esophageal perforation (Boerhaave's syndrome) is a rare clinical entity in which overindulgence in a large meal precedes
vomiting
and chest pain. Early diagnosis and aggressive management are keys to minimizing the morbidity and mortality. We report an unusual presentation of this already uncommon occurrence in a 33-year-old female. She presented to the Emergency Department with severe chest pain following
vomiting
with hematemesis after a large meal. The initial chest radiograph showed up nothing in particular. Dyspnea developed two days later, and a right-sided pleural effusion was seen on chest x-ray. Panendoscopy was highly suggestive of Boerhaave's syndrome. She underwent emergency operation. After three months of hospital care, she was discharged in relatively good condition. This case of right-sided pleural effusion extends the reported description of Boerhaave's syndrome.

Celiac artery compression syndrome occurs when the median arcuate ligament of the diaphragm causes extrinsic compression of the celiac trunk. We report a case of a 65-year-old woman who presented with a three-month history of postprandial abdominal pain, nausea and some
emesis
, without weight loss. There was a bruit in the upper mid-epigastrium and the lateral aortic arteriography revealed a significant stenosis of the celiac artery. At operation, the celiac axis was found to be severely compressed anteriorly by fibers forming the inferior margin of the arcuate ligament of the diaphragm. The ligament was cut and a vein by-pass from the supraceliac aorta to the distal celiac artery was performed. The patient remains well and free of symptoms two and a half years since operation.In this report we discuss the indications and the therapeutic options of this syndrome as well as a review of the literature is being given.
