Cardiac arrest, as a result of ventricular fibrillation or pulseless ventricular tachycardia, is a common phenomenon, and the only treatment available is defibrillation. Currently, defibrillators deliver either a monophasic or biphasic shock, depending on the device used. ⋯ These guidelines created a platform to address misconceptions that exist in the practice setting with regard to the use of biphasic defibrillators. The purpose of this literature review was to highlight the issues related to the practical use of biphasic energy, including optimal energy selection and safety.

Promoting adherence to self-care illness management strategies among patients with heart failure (HF) has been associated with a number of positive health outcomes. Yet, little is known about health outcomes related to self-care in the "sickest of the sick"-those patients with advanced HF who are approaching the end of life. ⋯ For example, what is meant by self-care illness management in patients who are symptomatic with exertion may differ from that of patients who are predominantly symptomatic at rest. Our challenge is to develop the simplest, least burdensome self-care illness management interventions that target the most meaningful outcomes for patients, their families, and the healthcare system.

Cardiovascular disease today remains a formidable foe affecting 1 in 3 Americans. The emergence of cardiac biochemical markers has provided clinicians unique insight into the state of the myocardium. In fact, cardiac biomarkers now represent an essential criterion in the definition of acute myocardial infarction. ⋯ The advantages and disadvantages of biomarkers will also be presented in the context of their clinical uses. Present markers are highly sensitive and specific to myocardial injury; however they do not specifically identify the method of injury. An exciting potential exists for future biomarkers to demonstrate enhanced specificity and earlier detection of compromised myocardium.

Heart failure (HF) is a complex and costly disease process associated with high morbidity and mortality. Implanted cardiac rhythm management devices are increasingly used in the HF population to provide therapies such as protection from sudden death and cardiac resynchronization therapy. ⋯ This article will review the evidence for using diagnostic information from cardiac rhythm management devices in the management of HF patients. Future advanced monitoring devices will also be discussed.
