Abstract: We report a case of arrhythmic storm in a patient with recent vaginal insertion of a device with release of levonorgestrel (synthetic progestin). A woman of 60 years was hospitalized for runs of monomorphic sustained ventricular tachycardia. She received a vaginal device levonorgestrel-releasing 2 days before admission. No history of associated cardiovascular or thyroid disease or risk factors was reported. Laboratory parameters as well as ECG and echocardiogram were normal. After 48 hours from removal of the vaginal device, the patient was asymptomatic and showed only single ectopic beats, sometimes in pairs. The subsequent coronary angiography, electrophysiological study and cardiac magnetic resonance resulted negative.

Open Journal of Anesthesiology (OJAnes) , 2013, DOI: 10.4236/ojanes.2013.35060
Abstract: Spinal anesthesia involves the introduction of local anesthetics into the subarachnoid space leading to the loss of sensation of pain. Common complications following spinal anesthesia include hypotension leading to nausea and vomiting, failure of the spinal and post dural puncture. Other uncommon complications include high and total spinal and spinal haematoma. In this report the patient experienced uncontrollable jerking of the lower limbs, hypertension, arrhythmias and cardiac arrest refractory to resuscitation.

Amiodarone Therapy for Cardiac Arrhythmias: Is It Associated with the Development of Cancers?  [PDF]
Padmavathi Mali, Michele M. Henry Salzman, Humberto J. Vidaillet, Shereif H. Rezkalla
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.43017
Abstract:

Amiodarone is used worldwide to treat cardiac arrhythmias, as well as highly symptomatic cases of atrial fibrillation. With this expanded use, especially following its 1985 United States Food and Drug Administration approval, and its use as a long-term therapy in common practice, reports of cancers temporarily related to amiodarone have begun to increase. Animal studies, several clinical trials, numerous case reports, and a population-based cohort study have suggested that cancers may be associated with amiodarone use. This review focuses on the ever increasing evidence in the literature that suggests amiodarone therapy, especially with long-term use, may increase the potential risk of cancer development. It also expresses the need for more definitive studies to be conducted to provide clinicians with a clear answer to this important question.

S. Panko, A. Mishurov, V. Evstratko, A. Gorchakovsky
Modern Instrumentation (MI) , 2016, DOI: 10.4236/mi.2016.51001
Abstract: The broken rhythm of the heart activity of a person can lead to fatal consequences if it is not detected at an early stage. The article described a device for counting and indicating the number of violations of rhythm of cardiac activity. The device is intended for home use and does not require medical knowledge. If the patient will notice a trend towards the increasing number of arrhythmias, he must seek for cardiology advice.

Abstract: purpose: to describe the presentation, diagnosis and treatment of fetal supraventricular tachyarrhythmias in a series of fetuses followed in a tertiary fetal cardiology center. methods: twenty-five fetuses with diagnosis of supraventricular tachyarrhytmia were reported from january 1989 to october 1997, among 3117 pregnant women referred for fetal cardiac evaluation. results: there were 17 fetuses with the diagnosis of supraventricular tachycardia (svt) and 8 patients with atrial flutter (af). gestational age ranged from 26 to 40 weeks. twelve patients were hydropic at presentation (6 with svt and 6 af). four fetuses with svt showed structural abnormalities (two with ebsten's anomaly and two with vsd). all patients were admitted to the fetal cardiology unit for monitoring and treatment. among 17 fetuses with svt, twelve showed good response to digoxin administration, but this drug was not useful in any of the patients with flutter. in two patients with svt and in six with af, the pregnancy was interrupted to perform post-natal cardioversion. the mortality rate was 3/17 in the svt group (including 2 patients with ebstein's anomaly and 0/8 in the flutter group) conclusion: fetal supraventricular tachyarrithmias are rare in the general population. nevertheless, the fetus may present with severe heart failure and death. considering the satisfactory therapeutic response, accurate diagnosis and early treatment of these conditions are extremely important.

Lorentz, Michelle Nacur;Vianna, Bruna Silviano Brand?o;
Revista Brasileira de Anestesiologia , 2011, DOI: 10.1590/S0034-70942011000600013
Abstract: background and objectives: cardiac dysrhythmias are relatively common in the perioperative period and should be adequately diagnosed and treated by the anesthesiologist whenever indicated. the objective of this article was to review the most relevant aspects of cardiac dysrhythmias, as well as establishing the cause-effect relationship between drugs used in the perioperative period and dysrhythmias. contents: the mechanisms of dysrhythmias, drugs that can potentially cause dysrhythmias, besides diagnosis and treatment in the perioperative period are presented. conclusions: perioperative dysrhythmias oftentimes do not require treatment and in others the treatment can generate iatrogenicity. therefore, the knowledge of cardiac dysrhythmias and triggering factors allows a better approach of the perioperative period by the anesthesiologist avoiding wrong or unnecessary treatment.
