Overdrive Pacing - StatPearls - NCBI Bookshelf
2023年4月24日 · Using ATP to override a native dysrhythmia is also called overdrive pacing (ODP). Temporary transcutaneous pacing (TTCP) uses external pads to transmit an electrical impulse through the skin, subcutaneous soft tissue, and chest wall to …

2023年4月24日 · Today, TCP is available in a broad spectrum of critical care settings, from pre-hospital to the intensive care unit, delivered via a variety of modalities, including transcutaneous, transvenous, epicardial, and transesophageal. This activity will focus on temporary cardiac pacing in critical care settings.
Overdrive pacing - UpToDate
During overdrive pacing, the membrane becomes hyperpolarized and maximum diastolic potential increases to -85 mV, resulting in part from the accumulation of sodium ions, activation of the sodium-potassium pump, and an increased influx of potassium as sodium is extruded.
Overdrive Pacing for Persistent Torsades de Pointes and Pulseless ...
Overdrive pacing has been shown to effectively terminate drug-induced prolonged QT intervals and consequent TdP by shortening the QT interval. Therefore, it is important to acknowledge the role that overdrive pacing has to offer.
Torsades de Pointes: Approach to resuscitation - First10EM
2017年1月9日 · There are 2 observational studies demonstrating an association between magnesium use and termination of torsades, causing the AHA to give in a class IIb LOE C rating. 1 The ECC guidelines grade the evidence for overdrive pacing, isoproterenol, beta-blockers, and lidocaine all as “indeterminate”. 2 There are no randomized trials of pacing to ...

2023年3月4日 · Overdrive pacing is an effective management strategy for TdP. Amiodarone and anti-arrhythmic medications remain an important trigger to identify in the management of these patients.
Overdrive pacing: an approach to terminating ventricular
The article provides an introduction to the concept of temporary overdrive (or rapid-burst) ventricular pacing as a viable treatment option for the termination of recurrent monomorphic ventricular tachycardia.
Overdrive pacing for ventricular fibrillation storm after myocardial ...
2024年10月18日 · Overdrive pacing therefore enables physicians to achieve acute control over arrhythmia recurrence and effectively ‘wait out the storm’ until recovery. This strategy limits the need for other invasive therapies, such as circulatory assistance or challenging emergency catheter ablation procedures.
Diagnostic value of tachycardia features and pacing maneuvers …
2000年8月1日 · An atrial-atrial-ventricular response upon cessation of ventricular overdrive pacing was diagnostic of atrial tachycardia, and this maneuver could be applied to 78% of all tachycardias.
