Summary
Selective site pacing (SSP) using the Select Secure System™ offers a versatile approach for pacing in the right atrium, right ventricle, and His-bundle region, demonstrating successful implantation and good pacing parameters.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Selective site pacing (SSP) in the right ventricle mitigates adverse hemodynamic effects of apical pacing.
- Right atrial SSP can prevent atrial fibrillation and slow disease progression.
Purpose of the Study:
- To describe the clinical use of a transvenous 4-French catheter-delivered lead for SSP.
- To evaluate the feasibility and outcomes of SSP across multiple centers.
Main Methods:
- A multicenter observational study enrolled 574 patients indicated for an implantable device.
- Selective site pacing was achieved using the Select Secure System™.
Main Results:
- Lead implantation was successful in 570 patients.
- SSP was performed in the atrium (interatrial septum, coronary sinus, Bachman bundle), ventricle (RVOT), and His-bundle region (direct or para-Hisian).
- A lead-related complication rate of 2.6% was observed during a mean follow-up of 20 months.
Conclusions:
- The Select Secure System™ enables effective pacing at various sites within the right atrium, right ventricle, and His-bundle region.
- This system facilitates diverse selective site pacing strategies in clinical practice.

01:30Pulse rhythm
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
01:24Modified-Release Drug Delivery Systems: Site-Targeted
Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
