Fatal septic shock caused by candida myocarditis associated with malignant lymphoma and Epstein-Barr virus mediated disorder  [PDF]
Salah A. M. Said, Bart J. F. Liebrand, Nersing Bansraj, Erik Eijken
Open Journal of Internal Medicine (OJIM) , 2011, DOI: 10.4236/ojim.2011.12007
Abstract: A 60-year-old man with known epilepsy was admitted to our hospital due to hypotension, fever and arrhythmia. He was treated medically and myocardial infarction was ruled out. Treatment of septic shock was established according to the guidelines of the early goal-guided therapy including vasopressors, inotropic agents, mechanical ventilation, and hemofiltration in combination with empirical treatment with antimicrobial drugs and hydrocortisone. The patient’s condition deteriorated rapidly into multiorgan failure resulting in a fatal outcome. Antemortem blood cultures were sterile. Autopsy findings were compatible with Epstein-Barr virus mediated lymphoproliferative disorder, malignant lymphoma, disseminated candidiasis and candida myocarditis. Post-mortem blood and tissue cultures were positive for growth of candida glabrata and candida albicans, respectively. The post-mortem examination documented Epstein-Barr virus mediated lymphoproliferative disorder and malignant small cell lymphoma associated with candida myocarditis. Prior to death, the patient did not receive antiviral or antifungal treatment. Fatal candida myocarditis associated with septic shock secondary to disseminated candidiasis in a 60-years old male patient with prior unknown immune compromised state caused by Epstein-Barr virus mediated lymphoproliferative disorder and malignant lymphoma is described.

Abstract:

临床上,中毒性心肌炎引发恶性心律失常的病例少有报道。我们汇报一位中年患者吸入污染毒物后出现恶性心律失常的病例。特别是患者在短时间内出现的心电图动态变化令人迷惑,值得探究。我们也提出在类似情况下积极处理的建议。

In clinic, there are few cases of malignant arrhythmia caused by toxic myocarditis. We report a case of malignant arrhythmia following a middle-aged patient who was contaminated with toxic pollution. In particular, the change of electrocardiogram of the patient in short duration is confusing. It is worth exploring. Suggestions for active treatment in similar cases are also presented.

Relationship of serum magnesium level and supplemental magnesium dosage with post coronary artery bypass graft surgery arrhythmias
Najafi M,Haghighat B,Ahmadi H
Tehran University Medical Journal , 2007,
Abstract: Background: Atrial and ventricular arrhythmias are among the most common complications after coronary artery bypass graft (CABG) surgery. Previous studies demonstrated that cardiopulmonary bypass itself results in reduced serum magnesium levels. In this study, we evaluated the effect of total blood magnesium level (TMG) on the prevention of perioperative arrhythmias with routine regimens of 2-4 grams supplemental magnesium (SMG). Methods: TMG was measured in patients who were scheduled for CABG on three occasions: just before anesthesia, just after entering the intensive care unit (ICU) after completion of the sugery, and on the first morning after the operation. Patients were evaluated for primary cardiac rhythm and other variables that could have an influence on the magnesium level, including serum creatinine, urine output in the operating room and diuretic therapy. The SMG dosage was also recorded in the operating room and ICU. Patients were then evaluated for the rate and type of arrhythmia for the next three days. Results: The mean TMG levels in 174 cases were 2.2 (0.5), 2.6 (0.6) and 2.4 (0.6) mg/dl for the three occasions, respectively. The mean SMG was 2.5 (1.2) grams. Of 164 patients, 51 (31%) developed the following post-operative arrhythmias: AF (7.3%), non-AF SVA (15.2%) and ventricular (16.5%). The mean serum creatinine level and urine output were 1.2 mg/dl and 1800 ml, respectively. Although there was a significant difference between the TMG levels on the three different occasions (P<0.001), all values were within normal range. When we stratified the TMG levels of the patients based on administered SMG, the Mentel-Haenszel test revealed no significant difference between the first and third TMG (P=0.6). Although the TMG levels were higher in arrhythmic patients compared to those without arrhythmia (2.25 vs. 2.14 mg/dl), both values were within the normal range and there was no significant difference between the two groups. Serum creatinine levels and urine volume were not related to TMG levels. Conclusion: This study indicates that routine magnesium administration has no significant effect on SMG levels. Also, serum creatinine and urine output are not determinant factors for SMG administration. There was no correlation between TMG levels and perioperative arrhythmia. We conclude that the routine regimen of magnesium administration has no effect on the incidence of perioperative arrhythmia, though it is necessary for maintaining normal magnesium levels.
Orthodromic Atrioventricular Reciprocating Tachycardia in a Dalmatian  [PDF]
Marlos G. Sousa, Stephany B. Lucina, Roberta Carareto
Open Journal of Veterinary Medicine (OJVM) , 2018, DOI: 10.4236/ojvm.2018.81001
Abstract: Supraventricular tachyarrhythmias may be caused by macroreentry circuits involving the AV node and accessory pathways. This paper reports a case of suspected orthodromic atrioventricular reciprocating tachycardia in an 18-month-old Dalmatian admitted with dyspnea and a lifelong history of fatigue. Cardiac auscultation documented a regular fast pace with no heart murmurs. The electrocardiogram characteristics were consistent with supraventricular tachycardia, with very regular RR interval and narrow QRS complexes. At lead II, we identified negative P waves buried within the ST segment, which resulted in a RP-to-PR ratio of 0.60, but in aVR these P waves were positive, suggesting a retrograde conduction of electrical impulses throughout the atrial myocardium. The echocardiographic study showed volume overload, and a decreased fractional shortening was calculated when SVT was sustained, highlighting its impact on systolic function. This is likely the first description of an orthodromic atrioventricular reciprocating tachycardia in a Dalmatian, and although cardiac mapping was not available to confirm this suspicion, all electrocardiograpic features were supportive of such arrhythmia.
Anaesthesia Management for Ablation Therapy in Post Heart Transplant Arrhythmia  [PDF]
Sunisa Prapaitrakool, Daniel Tom Bainbridge, Ronit Lavi
Open Journal of Anesthesiology (OJAnes) , 2013, DOI: 10.4236/ojanes.2013.38074
Abstract:

In this case series we describe the anaesthetic management of atrial ablation for arrhythmia in three post heart transplant patients. These patients provide a unique challenge to the anaesthesiologist, as heart physiology, end organs effects, procedural related factors should all be part of the specific anaesthetic plan tailored for each patient individually. The different anaesthetic techniques applied, and procedure related complications are evaluated. Anaesthetic management, procedural related difficulties, pharmacologic aspects, and possible associated complications are reviewed.

Open Journal of Anesthesiology (OJAnes) , 2014, DOI: 10.4236/ojanes.2014.48026
Abstract:

The efficacy of landiolol hydrochloride, an ultrashort-acting b-blocker with high b1 selectivity, has been confirmed in patients undergoing cardiac surgery in Japan, but there have been few reports about its use for patients having lung resection. We investigated the safety of continuous infusion of landiolol in patients undergoing lung resection. Between May 2008 and May 2011, 200 patients scheduled for lung resection were enrolled. Patients who underwent surgery before the introduction of landiolol in February 2010 were studied retrospectively (Group C) and were compared with those who received landiolol along with surgery (Group L). During the 48-hour study period, the incidence of arrhythmias, changes in heart rate and blood pressure, and occurrence of adverse reactions were examined. The white blood cell count and C-reactive protein level were measured before and after surgery to assess the anti-inflammatory effect. The heart rate was significantly lower in Group L throughout the study period. No patient in Group L developed hypotension requiring discontinuation of landiolol therapy, and no respiratory symptoms (including asthma or hypoxemia) were observed. White blood cell and C-reactive protein were significantly increased after surgery in both groups, and there were no between-group differences. Arrhythmic events occurred in 1.1% (1/99) and 9.2% (7/76) of Group L and Group C, respectively. One patient in Group C developed ventricular tachycardia. Landiolol can be administered safely during the perioperative period in patients undergoing lung resection.

Resetting of Cardiac Ventricular Tachycardia Storm with Intravenous Potassium Chloride: A Case Report  [PDF]
Gal Sella, Sharon L. Kracoff
Case Reports in Clinical Medicine (CRCM) , 2018, DOI: 10.4236/crcm.2018.72013
Abstract: Ventricular Tachycardia Storm (VTS) with hemodynamic instability is a life-threatening arrhythmia more often presents in patients with structural heart disease. Lack of response to cardioversion and/or antiarrhythmic drugs will have fatal consequences. We report a case of a hemodynamically unstable patient with Ventricular Tachycardia Storm refractory to intravenous antiarrhythmic medications, which finally responded to a slow bolus of IV potassium chloride. This case emphasizes the importance of identifying an electrolyte imbalance as a possible cause of a Ventricular Tachycardia storm and its rapid correction as an addition to the usual pharmacological treatment.

Open Journal of Anesthesiology (OJAnes) , 2015, DOI: 10.4236/ojanes.2015.54013
Abstract: Purpose: To examine the use of intravenous dantrolene in hospitalized patients. Materials and Methods: Medical Records of patients treated with intravenous dantrolene between 2007 and 2012 at 6 teaching hospitals were reviewed. Temperature, muscle rigidity, creatine kinase levels, and mortality were assessed in association with dantrolene use. Results: Twenty-five patients received intravenous dantrolene, 9 patients with neuroleptic malignant syndrome (NMS), 8 with hyperthermia due to sepsis, 4 with NMS and sepsis, 2 for malignant hyperthermia (MH), and 2 with hypermetabolic syndrome associated with juvenile diabetic ketoacidosis. Dantrolene was administered as a bolus of 1 - 3 mg/kg. Core temperature decreased after dantrolene administration in all groups but significant only for MH, NMS cases (Pre 102.3 ± 0.9°F vs. Post 99.5 ± 0.9°F; p < 0.001), in Sepsis cases (Pre 104.3 ± 1.5°F vs. Post 100.6 ± 1.0°F; p < 0.001). Mean rigidity scores decreased in all groups but significant only for NMS cases, and mean CK did not change significantly in any group. Conclusion: Dantrolene was associated with reductions in temperature and rigidity in hyperthermia of diverse origins in patients admitted to Intensive care settings.

Arrhythmia Diagnosis Following An ICD Shock
Roy M. John
Indian Pacing and Electrophysiology Journal , 2004,
Abstract: A 70 year old male underwent placement of a Medtronic Marquis DR ICD following syncope. He has coronary artery disease and severe LV dysfunction and was inducible for rapid hemodynamically unstable ventricular tachycardia at intracardiac electrophysiological study prior to implantation of the ICD. Three weeks later, he presents with an ICD shock. He had been drinking excessive amounts of alcohol and experienced lightheadedness prior to experiencing the ICD shock. A ventricular arrhythmia is appropriately converted by the ICD shock
