“…In our study, 3 patients survived an episode of out-of-hospital cardiac arrest with documented VF, the remaining patients presented with recurrent syncope. Transient or nonsustained VF may be the reason for presentation with syncope [9, 10, 11, 12]. In a review of 163 cases, men (n = 150) far outnumbered women (n = 13) and 58% of patients were of Asian ancestry [13].…”

Characteristics of Chinese Patients with Symptomatic Brugada Syndrome in Taiwan

Since 1992, the Brugada syndrome has been increasingly recognized worldwide, although its incidence and distribution remain unclear. In Asia, several cases have been reported in Japan, Thailand, Singapore, and Vietnam. However, little information is available from the Chinese population. Since June 1997, we have identified 10 patients with the diagnosis of the Brugada syndrome from six hospitals in Taiwan. All patients were male with the mean age of 46 ± 7 years (range 36–61). They all had a normal chemistry profile, coronary angiography and echocardiography. Clinical presentations varied from seizure and syncope to sudden cardiac death. MRI and ultrafast CT of the heart did not show any abnormalities. Sustained ventricular tachycardia/ventricular fibrillation (VF) was induced in 7 of 8 patients who underwent an electrophysiologic study. The pharmacological provocation test was positive in 4 of 5 patients. One of the 4 patients who had a genetic study showed SCN5A gene mutation. An implantable cardioverter defibrillator (ICD) was implanted in 8 patients. During a mean follow-up of 29 ± 17 months (range 2–54), 3 of 8 patients who had an ICD received appropriate ICD discharges after implantation. These 3 patients who were subsequently treated with antiarrhythmic agents have had no further recurrent ICD discharges. Two patients who refused ICD implantation are alive and well without taking antiarrhythmic agents. Our study showed that the clinical characteristics of our patients are similar to those described in the literature and that ICD is an effective treatment modality for patients with recurrent VF. However, antiarrhythmic agents may be beneficial for suppressing arrhythmia recurrences in selected patients.

“…Spontaneous termination of VF has been documented in a 62-year-old woman following an acute postero-lateral myocardial infarction 41, a 67-year-old woman with a syncopal episode after awakening from sleep 42, and a 21-year-old woman during exertion at night 43, although CAS was not documented in those reports. In a study of VF episodes in patients with implantable cardioverter defibrillators 44, 43% were asymptomatic and 40% were nonsustained episodes.…”

Coronary artery spasm (CAS), an intense vasoconstriction of coronary arteries that causes total or subtotal vessel occlusion, plays an important role in myocardial ischemic syndromes including stable and unstable angina, acute myocardial infarction, and sudden cardiac death. Coronary angiography and provocative testing usually is required to establish a definitive diagnosis. While the mechanisms underlying the development of CAS are still poorly understood, CAS appears to be a multifactorial disease but is not associated with the traditional risk factors for coronary artery disease. The diagnosis of CAS has important therapeutic implications, as calcium antagonists, not β-blockers, are the cornerstone of medical treatment. The prognosis is generally considered benign; however, recurrent episodes of angina are frequently observed. We provide a review of the literature and summarize the current state of knowledge regarding the pathogenesis of CAS.

“…Spontaneous rhythm conversion has been described in both healthy adults (229,230) CIRC patients could receive amiodarone, lidocaine, atropine, bicarbonate, adrenaline and/or vasopressin based on EMS sites and their routines. (168) Although drug use was noted in the case report forms, the timing of drug delivery was not noted, and we do therefore not know if drugs were administrated in association with these episodes with rhythm conversion.…”
