INTRODUCTION. Takotsubo syndrome (TTS) is a rare condition that mimics an acute myocardial infarction. It is associated with precordial pain, ST segment elevation, absence of coronary occlusion and reversible deformation of the left ventricle due to anteroapical dyskinesia that is reminiscent of a Japanese art of fishing octopuses (tako-tsubo). It is related with emotional and physical stress, and is thought to be mediated by an acute release of catecholamines. CASE REPORT. An 83-year-old woman with hypertension. She was admitted to the heart unit with a suspected acute coronary syndrome and respiratory failure, and thus required mechanical ventilation. An echocardiography scan showed severe ventricular dysfunction with apical dyskinesia. Cardiac catheterisation ruled out heart disease and a ventriculography scan revealed a bloated systolic deformation of the anterior and apical segments (TTS). Attempts to withdraw ventilation were unsuccessful and the neurology department was consulted. A directed medical history revealed that the patient had been suffering from generalised weakness, and progressive dysphagia and dyspnoea for several months. Results of an edrophonium test were positive. Single-fibre electromyography showed a pathological jitter and acetylcholine anti-receptor antibodies were positive. The patient was treated with immunoglobulins, corticoids and pyridostigmine. A control echocardiogram showed resolution of the TTS. CONCLUSIONS. TTS must be considered within the extra-neurological complications arising from myasthenic crisis. The neurologist must take this into account when faced with any symptom or sign of a potentially cardiac origin in myasthenic crisis and other neurocritical conditions.

The typical symptoms of pheochromocytoma are palpitations, sweating, headaches and hypertension. We report a 70-year-old female admitted to the hospital due to a sudden onset of precordial pain with electrocardiographic changes. After admission the patient evolved with recurrent chest pain accompanied by hypertensive paroxysms and a pheochromocytoma was suspected. Measurement of catecholamines and metanephrines confirmed the diagnosis and an abdominal magnetic resonance localized the tumor. The patient underwent surgery with successful removal of the pheochromocytoma and was discharged in good conditions.

This study evaluated the effectiveness of YinTang and ChengJiang acupoints on patients with cardiac arrhythmia and neurocardiogenic syncope in emergency first aid. A 45 year old woman underwent acupuncture. She had a previous history of a valvuloplasty for rheumatic disease and two acute myocardial infarctions, followed by four catheterizations and an angioplasty. Needling of the YinTang acupoint and stimulation of the ChengJiang acupoint through acupressure were performed for 20 minutes soon after syncope and during tachycardia, hypertension, tachypnea, and precordial pain, without any effect on peripheral oxygen saturation (SpO2) or the glycemic index. Data were analyzed comparatively by using the following parameters at rest, during syncope, and at 1 minute and 10 minutes after an emergency acupuncture procedure: blood pressure; heart rate; SpO2; and respiratory rate. We found that acupuncture at YinTang and ChenJiang acupoints induced cardiovascular responses, increased the limits of the body's homeostasis, and normalized the patient's condition in the case of syncope. Acupuncture using a combination of ChengJiang and YinTang acupoints had an immediate effect on the autonomic nervous system and on maintaining homeostasis and energy balance in the body. Although this technique was effective, the patient was still referred to the Emergency Room.
