Sudden Cardiac Death | Study of Paced QRS Duration as a Marker of Sudden Cardiac Death

Sudden Cardiac Death research study

What is the primary objective of this study?

The purpose of the study is to determine whether prolonged paced QRS duration is a marker of sudden cardiac death in subjects with implantable cardioverter-defibrillators (ICD).

Who is eligible to participate?

Inclusion Criteria: - 18 years old or older - Male or female - Subjects followed in the ICD clinic at Pocono Medical Center who have undergone ICD implantation within 3 years prior to the date of enrollment, and those who undergo ICD implantation during the enrollment period, whether for primary prevention or for secondary prevention based on standard indications will be included in the study. - Patients with single chamber, dual chamber and biventricular devices manufactured by all three major vendors (Boston Scientific, St Jude Medical and Medtronic) will be considered. Exclusion Criteria: - Life expectancy of less than one year - Severe reaction to the adhesive material on ECG patches

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Sudden Cardiac Death

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
