Background: There have been limited data examining the temporal relationship between device-derived daily activity and ventricular arrhythmias (VAs).
Objective: We aimed to assess whether activity predicted VAs or VAs predicted changes in activity.
Methods: The CERTITUDE registry includes over 55,000 implanted devices active on Home Monitoring.
Background: Despite clear associations between arrhythmia burden and cardiovascular risk, clinical risk scores that predict cardiovascular events do not incorporate individual-level arrhythmia characteristics from long-term continuous monitoring (LTCM).
Objectives: This study evaluated the performance of risk models that use data from LTCM and patient claims for prediction of heart failure (HF) and ischemic stroke.
Methods: We retrospectively analyzed features extracted from up to 14 days of LTCM electrocardiogram (ECG) data linked to patient-level claims data for 320,974 Medicare beneficiaries who underwent ZioXT ambulatory monitoring.
The rapid growth in consumer-facing mobile and sensor technologies has created tremendous opportunities for patient-driven personalized health management. The diagnosis and management of cardiac arrhythmias are particularly well suited to benefit from these easily accessible consumer health technologies. In particular, smartphone-based and wrist-worn wearable electrocardiogram (ECG) and photoplethysmography (PPG) technology can facilitate relatively inexpensive, long-term rhythm monitoring.

- Catheter ablation for atrial fibrillation (AF) is widely researched, and this expert opinion aims to enhance future studies by applying lessons from past research and promoting consistency in methodologies.
- The effectiveness of these studies can improve with clearly defined endpoints and a thorough understanding of emerging technologies, as well as a need to revisit some current research methods.
- A panel of clinical experts has produced recommendations highlighting essential elements such as documenting clinical details, managing medications during trials, and assessing outcomes to aid in the standardization and quality of AF catheter ablation studies.
Article Synopsis
- Researchers evaluated the frequency of nonsustained ventricular tachycardia (NSVT) in patients with hypertrophic cardiomyopathy (HCM) using 14-day continuous ambulatory monitoring compared to traditional 48-hour monitoring.
- Out of 236 patients, nearly half experienced NSVT over the 14 days, with a significant number only detected during the extended monitoring period, indicating that the extended monitoring greatly increased diagnostic yield by 2.7 times.
- The findings suggest that many NSVT episodes, especially those considered higher risk, were missed in the initial 48 hours, highlighting the importance of longer monitoring periods to assess sudden death risk in HCM patients.
