1/62. Inappropriate shocks delivered by implantable cardiac defibrillators during oversensing of activity of diaphagmatic muscle.Two cases are reported (both men, one 72 and one 54 years old) of inappropriate shocks delivered by an implantable cardiac defibrillator (ICD) device, which oversensed the myopotentials induced by deep breathing and Valsalva manoeuvre. No damage to leads was associated with the oversensing of myopotentials. The mechanism of the inappropriate shocks was determined using real time electrograms. Modification of the duration of ventricular detection and decrease in sensitivity made it possible to avoid the oversensing of myopotentials and to deliver ICD treatment.- - - - - - - - - - ranking = 1keywords = shock (Clic here for more details about this article) |
2/62. Alteration in gastrointestinal and neurological function after electrical injury: a review of four cases.OBJECTIVE: Individuals exposed to an electrical injury develop a variety of complications, several of which are recognized years after the initial electrical shock. Alteration in gastrointestinal and nervous system function has been described in these patients, yet the frequency and character of these abnormalities are poorly understood. We reviewed records of 40 individuals with a history of electrical injury to identify evidence of delayed onset of complications. methods: Forty consecutive patients with electrical shock injuries were monitored for up to 5 yr after their traumatic event using a comprehensive systems review. Of the eight patients who described an alteration in their gastrointestinal and neurological functions, four agreed to undergo further testing. Investigations included a flexible sigmoidoscopy, anorectal manometry, stool evaluation, serological and biochemical serum analysis, and a psychological examination. RESULTS: Each of the four patients described an increase in stool frequency and urgency. Anorectal manometry detected a reduction in threshold to rectal balloon distention and an abnormal anal sphincter control. Bowel function improved with meselamine. Psychiatric symptoms involving memory and concentration were observed in varying degrees. CONCLUSIONS: To our knowledge, these induced physiological and psychological changes after exposure to electrical shock injury have not yet previously been described. Our findings should encourage further clinical investigations to better anticipate, diagnose, and manage these and other as yet unrecognized delayed complications of electrical shock injury.- - - - - - - - - - ranking = 0.66666666666667keywords = shock (Clic here for more details about this article) |

4/62. Implantable cardioverter defibrillator-an unusual case of inappropriate discharge during showering.The evolution of diagnostic information provided in implantable cardioverter defibrillators (ICDs) has paralleled the advances in the therapeutic options incorporated in these systems. Contemporary devices are capable of providing recordings of electrical events surrounding all delivered and aborted device therapy. This report presents un unusual case of inappropriate discharge of an ICD, resulting from electromagnetic interference. A transvenous ICD system (Sentry Hot Can 4310 HC, Telectronics Denver, CO), was implanted in a patient with ischemic heart disease due to episodes of ventricular tachycardia refractory to antiarrhythmic treatment. One month post-implant the patient reported two consecutive shocks from the device while showering. The non-physiological cycle length (100 ms) recorded in conjunction to the scenario of the event, raised the suspicion of electromagnetic interference through electrical current leakage in the bathroom, an hypothesis that was subsequently proved. This case report underscores that electromagnetic interference can become hazardous in common daily activities of patients with an ICD.- - - - - - - - - - ranking = 0.16666666666667keywords = shock (Clic here for more details about this article) |
5/62. Experience of the treatment of severe electric burns on special parts of the body.The treatment in these eight cases with severe electric burns on special parts of the body was successful. Our experience can be summarized as follows: (1) The role of the immediate measures including resuscitation at the scene of the accident cannot be understated. If the patient presents with a complex injury such as open pneumothorax, first aid should be provided immediately and then the patient should be transferred to a specialized treatment center. (2) General conditions such as the presence of shock, water-electrolyte balance, renal function, and others should be continuously monitored. (3) Antibiotics should be suitably administered and combined with antianaerobic drugs. (4) For different wound sites, different plans of treatment, including various immediate and delayed procedures, could be appropriate. In life-threatening cases such as exposed carotid artery, perforative injury of the chest wall, spinal cord damage, and others, first-stage repair using skin flap or myocutaneous flap must be performed after early debridement. For other wound sites, such as oral area and tongue, eye socket, and penis, second-stage reconstruction may be more suitable for better cosmetic appearance and function. (5) Adequate nutritional supply and early treatment of anemia may expedite wound healing.- - - - - - - - - - ranking = 0.16666666666667keywords = shock (Clic here for more details about this article) |

7/62. Neuropsychiatric profile of a case of post traumatic stress disorder following an electric shock.Exposure to extraordinary stressors or life-threatening events has been shown to result in negative cognitive, behavioural and emotional outcomes including the cluster of symptoms constituting Post Traumatic Stress Disorder (PTSD). This disorder has most often been studied in military veterans and victims of abuse who also show high rates of comorbid conditions. We report a case of PTSD following an electrical injury in a patient with no past psychiatric history. Implications for a full range of examinations including comprehensive neuropsychiatric testing are discussed. Results suggest that such approach addresses the complexity of a differential diagnosis between organic and psychiatric dysfunctions.- - - - - - - - - - ranking = 0.66666666666667keywords = shock (Clic here for more details about this article) |
8/62. Inappropriate discharges from an intravenous implantable cardioverter defibrillator due to T-wave oversensing.This report describes the clinical management of 2 patients with ventricular fibrillation (VF) who received inappropriate shocks from an implantable cardioverter defibrillator (ICD) due to T-wave oversensing. Cardiac sarcoidosis was confirmed as the underlying heart disease in 1 patient and idiopathic dilated cardiomyopathy in the other. Within 2 months after ICD implantation, both patients received several inappropriate shocks during sinus rhythm. Stored electrograms showed decreased R-wave amplitudes and increased T-wave amplitudes. The ICD sensed both R- and T-waves as ventricular activation, which met the rate criteria for VF treatment. Reprogramming the sensing threshold in association with administration of a drug to slow the heart rate decreased the incidence of the inappropriate shocks in both patients, but these palliative measures did not completely suppress the inappropriate shocks. To avoid T-wave oversensing, the repositioning or adding of a sensing lead is required. The potential risk of T-wave oversensing in ICD patients who have small R-wave amplitudes should be recognized.- - - - - - - - - - ranking = 0.66666666666667keywords = shock (Clic here for more details about this article) |
9/62. motor neuron disease after electric injury.The occurrence of motor neuron disease after electrical injury in six patients is reported and compared with patients from the literature. The patients were five men with spinal onset and one woman with bulbar motor neuron disease after electric shock. Two patients were struck by lightning and four by industrial electric shock. For all six of them, the disease started at the site of the electrical trauma. The mean delay for onset of motor neuron disease was 44 months. In four of the spinal patients the disease progressed slowly with mild handicap after several years. For the fifth patient, improvement was noted progressively. The patient with bulbar disease died 26 months after onset. A link between electric shock and motor neuron disease is likely, given the homogenous profile of the patients both in the five spinal cases presented here and in the literature. Bulbar onset has not been reported to date. However, in this patient the long delay between the electrical injury and motor neuron disease, together with the rapid evolution may suggest a chance association.- - - - - - - - - - ranking = 0.5keywords = shock (Clic here for more details about this article) |
