Effects of implantable cardioverter/defibrillator (ICD) shocks and antitachycardia pacing (ATP) on anxiety and quality of life (QoL) in ICD patients are poorly understood. METHODS: We evaluated changes in QoL from baseline to 9-month follow-up using the EQ-5D questionnaire in patients enrolled in the Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate Therapy (MADIT-RIT) (n=1,268). We assessed anxiety levels using the Florida Shock Anxiety Scale (1-10 score) in patients with appropriate or inappropriate shocks or ATP compared to those with no ICD therapy during the first 9 months postimplant...

BACKGROUND: During early experience with subcutaneous implantable cardioverter defibrillator (S-ICD(TM)), several patients had inappropriate shocks from TWOS during exercise. This prompted some operators to perform routine treadmill exercise test after implantation of S-ICD to screen for TWOS. Meanwhile, improvements have been made in the detection algorithms by the manufacturer. OBJECTIVE: To assess whether routine treadmill exercise post S-ICD(TM) implantation is warranted...

OBJECTIVES: To study the clinical profile and predictors of outcome in children with status epilepticus (SE) during resuscitation in pediatric emergency department. MATERIALS AND METHODS: This retrospective study was carried out in a tertiary care teaching hospital. Admission and resuscitation data of children, aged between 1 month and 12 years, treated for SE, between September 2013 and August 2014, were extracted using a standard data collection form. Our SE management protocol had employed a modified pediatric assessment triangle to recognize and treat acute respiratory failure, cardiovascular dysfunction (CD), and subtle SE until all parameters resolved...

BACKGROUND: Wavelet is a morphology-based algorithm for detecting ventricular tachycardia. The electrogram (EGM) source of the Wavelet algorithm is nominally programmed with the Can-RV coil configuration, which records a far-field ventricular potential. Therefore, it may be influenced by myopotential interference. METHODS: We performed a retrospective review of 40 outpatients who had an implantable cardioverter-defibrillator (ICD) with the Wavelet algorithm. The percent-match score of the Wavelet algorithm was measured during the isometric chest press by pressing the palms together...

Implantable cardioverter defibrillator (ICD) programming involves several parameters. In recent years antitachycardia pacing (ATP) has gained an increasing importance in the treatment of ventricular arrhythmias, whether slow or fast. It reduces the number of unnecessary and inappropriate shocks and improves both patient's quality of life and device longevity. There is no clear indication regarding the type of ATP to be used, except for the treatment of fast ventricular tachycardias (188 bpm-250 bpm) where it has been shown a greater efficacy and safety of burst compared to ramp; 8 impulses in each sequence of ATP appears to be the best programming option in this setting...

BACKGROUND: Pacemakers (PM) and implantable cardioverter defibrillators (ICD) may be indicated for sudden death prevention in myotonic dystrophy type 1 (DM1), however the risk of complications after the placement of these devices is unknown. OBJECTIVE: To compare the rate of device-related complications between PM and ICD implantations in patients with DM1. METHODS: Among 914 patients with DM1 included in the DM1 Heart Registry between January 2000 and January 2010, we retrospectively selected 23 patients who were implanted with an ICD and matched them to 46 controls with a PM on age, gender, and year of device placement...

The number of children and adult with congenital heart disease requiring implantation of cardiac pacemaker or cardioverter defibrillator is constantly increasing. The lead between stimulation/defibrillation site and the generator constitutes the main weakpoint of those devices despite the numerous recent technological advances: use of bipolar probes, corticoid elution electrodes, insulation improvement, magnetic resonance imaging (MRI) compatibility. Risk of device failure remains high in this population. Long term adverse events with endovascular devices remain high...

REVIEW
Keun Suk Park, Kyung Yeon Yoo
Arginine vasopressin (AVP), also known as antidiuretic hormone, is a peptide endogenously secreted by the posterior pituitary in response to hyperosmolar plasma or systemic hypoperfusion states. When administered intravenously, it causes an intense peripheral vasoconstriction through stimulation of V1 receptors on the vascular smooth muscle. Patients in refractory shock associated with severe sepsis, cardiogenic or vasodilatory shock, or cardiopulmonary bypass have inappropriately low plasma levels of AVP ('relative vasopressin deficiency') and supersensitivity to exogenously-administered AVP...

PURPOSE: Sepsis accounts for only 2% of the hospitalizations worldwide but more than 17% of total in-hospital mortality. Inappropriate antimicrobial selection and delays in appropriate therapy have been associated with reduced survival in severe sepsis and septic shock. No studies to date have exclusively targeted septic oncologic patients without hypotension. METHODS: This study was a retrospective chart review of 100 adult cancer patients presenting to the emergency department with sepsis without hypotension...

We present a case of a patient with a baroreceptor activation therapy (BAT) receiving a subcutaneous ICD. We anticipated two possible hazardous interactions between the two devices. Stimulation by the BAT could be adjudicated as noise and result in under-detection of ventricular arrhythmias or it might be misinterpreted as ventricular arrhythmias and lead to inappropriate shocks. Postop ensing occurred, the upper limit of pulse width of the BAT was limited because of noise detection by the S-ICD, but the upper limit of amplitude was limited by patient's discomfort...

Screening tests conducted at rest may be inadequate for the prediction of the T-wave oversensing (TWOS) in subcutaneous implantable cardioverter defibrillator (S-ICD) candidates with Brugada syndrome (BrS) because of the dynamic nature of electrocardiogram (ECG) morphology. We evaluated the utility of ECG screening during drug challenge (DC) for prediction of TWOS in BrS patients implanted with an S-ICD. The study enrolled 6 consecutive BrS patients implanted with an S-ICD. In addition to baseline ECG screening, pre-implant screening during DC using a sodium channel blocker was performed in all patients...

BACKGROUND: ICDs efficiently terminate life-threatening arrhythmias, but complications occur during long-term follow-up. Patients' own perspective is largely unknown. The aim of the study was to describe experiences of hypertrophic cardiomyopathy (HCM) patients with implantable defibrillators (ICDs). METHODS: We analyzed 26 Swedish patient interviews using hermeneutics and latent content analysis. RESULTS: Patients (aged 27-76 years) were limited by HCM especially if it deteriorates into heart failure...

Painful trigeminal neuropathy attributed to a space-occupying lesion (code 13.1.2.5 in the International Classification of Headache Disorders, 3rd edition [beta version]) is an orofacial pain condition that has characteristics of classical trigeminal neuralgia but is caused by a space-occupying lesion. We present 4 cases of intracranial lesions mimicking odontogenic pain as follows: case 1, a 61-year-old woman presented with a chief complaint of aching soreness in the right mandibular molar area for 1 year; case 2, a 59-year-old man presented with severe pain in the left maxillary and mandibular molars; case 3, a 72-year-old man presented with a chief complaint of facial shock-like pain on the left side; and case 4, a 75-year-old man presented with a chief complaint of paroxysmal pain and numbness in the buccal gingiva of the right mandibular molar region...

António Heitor Reis
Following a hypothesis developed in an earlier paper, here it is discussed how deviations of blood pH from the normal range (namely states of acidemia) together with high blood levels of free fatty acids (FFA) may offer a rationale for many important risk factors for cardiovascular diseases (CVD) by shaping a context for formation of fatty acid micelles and vesicles with an acidic core, which fuse with the endothelia, disrupt vital cell processes, and thereby may initiate atherosclerotic plaque formation. Acidemia may arise primarily from dysregulation of the systemic buffers that control blood pH, chronic diseases of kidneys and lungs, inappropriate diet, or may be induced by some common drugs...
