WASHINGTON, DC — The U.S. Food and Drug Administration, in collaboration with major implantable pacemaker and ICD manufacturers, demonstrated the effects of emissions from radio frequency identification (RFID) readers on common implantable cardiac devices. According to research published in the January edition of the HeartRhythm Journal, the official journal of the Heart Rhythm Society, the observed effects may cause increasing complications as RFID use expands in the medical device field.

WASHINGTON, DC — March 1, 2010 – Analysis of ICD patients enrolled in four different trials found patients with life-threatening ventricular arrhythmias (VA) treated only with antitachycardia pacing (ATP) have higher survival rates than VA patients who experienced at least one shock-treated episode. According to research published in the March edition of the HeartRhythm Journal, the official journal of the Heart Rhythm Society, 80.2% of VA episodes were successfully treated with ATP-only therapy from an ICD.
DENVER, May 13, 2010 – According to a sub-study of the Multicenter Automatic Defibrillator Implantation Trial-CRT (MADIT-CRT), females receive a clinically significant benefit from cardiac resynchronization therapy devices (CRT-D) compared to men. New research presented today at Heart Rhythm 2010, the Heart Rhythm Society’s 31st Annual Scientific Sessions, indicates that CRT-D therapy reduces all-cause mortality and heart failure (HF) and death end point in females, but not in males.
WASHINGTON, July 1, 2010 — New large meta-analysis from five primary prevention randomized implantable cardioverter-defibrillator (ICD) studies shows a smaller impact of Sudden Cardiac Death (SCD) on overall mortality in women. According to research published in the July edition of the HeartRhythm Journal, the official journal of the Heart Rhythm Society, women in primary prevention ICD trials have the same overall mortality as men, while experiencing significantly less appropriate ICD interventions. With more than 1,600 women, this meta-analysis includes the largest cohort of women to date.
Lack of awareness and treatment of sudden cardiac arrest (SCA) puts African Americans at greater risk of death from the condition, according to a new national survey released today by the Heart Rhythm Society (HRS). The survey findings uncovered significant perception gaps between healthcare providers and consumers when it comes to understanding the condition, its symptoms, risk factors and treatments. Responsible for more than 350,000 U.S. deaths each year, SCA occurs when the heart suddenly and unexpectedly stops beating. Approximately 95 percent of SCA cases result in death; however, it is proven most deadly in African Americans.
WASHINGTON – The Heart Rhythm Society (HRS) and the American College of Cardiology Foundation (ACCF), today released the HRS/ACCF Expert Consensus Statement on Pacemaker Device and Mode Selection.The expert consensus statement was developed in collaboration with the Society of Thoracic Surgeons, endorsed by the American Heart Association, and published online today as part of the August edition of HeartRhythm, the official journal of the Heart Rhythm Society, as well as the Journal of the American College of Cardiology. The statement is the first of its kind to specifically address pacemaker device and mode selection, expanding upon the ACC/AHA/HRS 2008 guidelines for device-based therapy of cardiac rhythm abnormalities.
WASHINGTON, DC — New research reveals that abandoning a nonfunctioning lead in an ICD patient is safe and does not pose a clinically significant risk of complication. The lead is the wire placed in the heart that transmits the heart's electrical signals to the defibrillator for interpretation. The new study published in the January edition of the HeartRhythm Journal, the official journal of the Heart Rhythm Society, suggests that the practice of abandoning nonfunctioning leads does not result in additional risk to the patient and lead extraction should be reserved for cases of system infection or when large numbers of leads have been abandoned.
