AIMS: Several case reports have demonstrated negative interactions between various physiotherapy modalities and cardiac rhythm devices (CRD). Fear of these potential interactions may lead to suboptimal utilization of physiotherapy treatments in CRD patients. No prior review of available guidelines, or management strategies, on the interaction between physiotherapy modalities and CRD patients has been reported. To review existing guidelines regarding the use of physiotherapy modalities in patients with pacemakers and/or implantable cardioverter-defibrillators (ICDs).

Ethics committees are use [sic] to questions concerning the withdrawal of life-support. Such questions become increasingly complex when that life-support is implantable, like a pacemaker. This essay seeks to address the question of under what, if any, circumstances it would be permissible to discontinue the use of such implantable devices.

The implantable cardioverter-defibrillator (ICD) is today widely used for the treatment of sudden cardiac near-death episodes as a result of malignant ventricular dysrhythmia. After examining the literature, only four descriptive studies, all carried out in the USA, with a qualitative analysis based on ICD-patients' own perspectives on their life situation have been found. The aim of this study was to describe how patients living with an ICD-device in south-western Sweden conceive their life situation.

Modern medicine is often accused by diverse critics of being "too materialistic" and therefore insufficiently holistic and effective. Yet, this critique can be misleading, dependent upon the ambiguous meanings of "materialism." The term can refer to the prevalence of financial concerns in driving medical practice. Alternatively, it can refer to "mechanistic materialism," the patient viewed as a body-machine. In each case, this article shows that this represents not authentic "materialism" at play, but a focus upon high-level abstractions.

BACKGROUND: The reduction in adrenergic activity and anxiety associated with meditation may be beneficial for patients with implantable cardioverter defibrillators. PURPOSE: This study aims to determine the feasibility of a phone-delivered mindfulness intervention in patients with defibrillators and to obtain preliminary indications of efficacy on mindfulness and anxiety. METHODS: Clinically stable outpatients were randomized to a mindfulness intervention (eight weekly individual phone sessions) or to a scripted follow-up phone call.

BACKGROUND: Patients with ischemic heart disease may require antianginal and/or antiarrhythmic regimes. These patients may also be candidates for implantable defibrillators. The effects of antiarrhythmics, such as bretylium, or calcium antagonists, such as verapamil, nifedipine, or diltiazem on internal defibrillation efficacy have been inconsistent or are unknown. METHODS AND RESULTS: The effects of bretylium and verapamil on the energy requirements for ventricular defibrillation threshold (DFT) were determined in 92 open-chest anesthetized pigs.

At the end of the 19th century, there was both experimental and clinical evidence that coronary artery obstruction causes ventricular fibrillation and sudden death and that fibrillation could be terminated by electric shocks. The dominant figure at that time was McWilliam, who in 1923 complained that "little attention was given to the new view for many years." This remained so for many decades.

AIMS: The development of implantable cardioverter-defibrillators (ICDs) with QRS morphology discrimination and dual-chamber sensing capabilities has improved the differentiation of supraventricular from ventricular tachycardias (VTs). Inappropriate ICD discharges may result from extracardiac signals caused by electromagnetic interference (EMI), because of electric fields and leakage currents from domestic or medical electrical devices, damaged sensing leads, and various cardiac and extracardiac signals that mimic VT and/or ventricular fibrillation.

Expert Opinion on Emerging Drugs

IMPORTANCE OF THE FIELD: The present review is aimed at going over the pharmacological profile (and the clinical impact) of the emerging drugs involved in the management of patients with ST-elevation myocardial infarction (STEMI) in order to provide the cardiologists who deal with these patients in the early phase with the most recent evidence on this topic. AREAS COVERED IN THIS REVIEW: Anticoagulant and antiplatelet drugs are the main cornerstones of therapy in the treatment of STEMI patients undergoing primary percutaneous coronary intervention (PCI).
